201009873 VI. Description of the Invention: [Technical Field] The present invention relates to a switching device, and more particularly to a switching device for automatically opening a disconnecting mechanism of a switching device. [Prior Art] A switching device having a disconnecting mechanism typically includes the preparation of an electromagnetically operated disconnecting mechanism, starting from a state of being turned on and for breaking the switching device according to the presence of a predetermined breaking or powering down condition Turn on or off. However, in some cases, reliable disconnection (power down) of the switching device cannot be guaranteed. For example, in the case of an electromagnetic disconnecting mechanism, the magnetic force applied by the disconnecting mechanism is insufficient to perform or terminate the power-off process. This results in a reduction in the reliability of the switching device. In this case it is possible to construct the disconnecting device by means of a more efficient coil which is added and which is used to generate an increased magnetic force, wherein this results in a higher cost and a larger and larger component size. the weight of. SUMMARY OF THE INVENTION It is therefore an object of the present invention to design a switching device having a disconnecting mechanism such that a reliable disconnection of the switching device is ensured in the event that the disconnecting mechanism has a reduced structural size and low power. . This object is achieved by a switching device according to the feature 201009873 stated in the first item of the patent application. In particular, the switching device according to the invention comprises: a switching unit having a switching body and a control member, the switching body being movable between the first and second positions and a plurality of contact elements being arranged On the switch body, the contact element is in contact with a fixed contact element located opposite the plurality of contact elements when moving from the first position to the second position in order to switch on the circuit. Moving between the position and the first position to hold the body in its second position when the control member reaches its second position; and a disconnecting unit for opening the switch device when the switch When the body and the control member are in their respective first positions' and when there is a predetermined breaking condition, the control member moves to the first position by means of the operating device of the breaking unit, so that the switch body moves to its first The circuit is opened and disconnected, wherein the control device and the control members located in their own second position are spaced apart from each other by a predetermined distance without a predetermined breaking condition. In this way, it is possible to achieve a reliable disconnection or de-energization of the entire switching device and also ensure a reliable disconnection or de-energization of the entire switching device under adverse conditions, since the actuation of the single & A predetermined distance is provided with respect to the control of the switching unit. By igniting the disconnection unit in the presence of a predetermined disconnection condition (which detects the presence of a predetermined disconnection condition), the disconnection unit, together with its operating means, moves the switching unit to an open or de-energized state . In particular, the disconnecting unit causes the control member to maintain the switching body of the switching unit in its second position and thus remain in the open state (turning on the 201009873 circuit) to move to the control unit of the switching unit In the first position, the switch body is also moved to its first position and the plurality of closed contacts are opened, causing the circuit to be opened.

In order to bring the control element from the second position (the switch body is fixed in its second position and thus fixed in the switched-on position) by a predetermined distance between the actuating device of the disconnecting unit and the control unit of the switching unit Moving to the first position, sufficient energy is provided for this purpose, so that in the case of a disconnecting unit having a small size, the control member can also be reliably moved from its second position to its first position and thus the switching unit and The entire switching device is reliably disconnected or de-energized. According to other configurations, the device has a disconnecting unit in the form of an electromagnetically operated disconnecting unit. The electromagnetically operated breaking unit can comprise at least one magnetic coil and at least one magnetic core. The electromagnetically actuated disconnecting unit can in particular have at least one coil and at least one magnetic & the power supply to the coil in accordance with the presence of a predetermined open signal in order to energize the coil, on which the actuating device is arranged The magnetic core and the actuating device move in the direction of their action when the coil is actuated for moving the control element of the switching unit from its second position to its in particular, when there is a predetermined breaking condition, the magnetic core and the actuating device can be oriented towards the control The direction of movement of the piece is at least predetermined (four) such that a collision occurs on the control element of the switching unit, which collides with the kinetic energy of the pre-registration. Furthermore, the core of the disconnecting unit and the actuating device can be held in the rest position i′ by the spring force without the breaking condition determined in advance 201009873 and can be oriented in the case of a predetermined breaking condition. The direction of the control member is accelerated to overcome a predetermined distance. In this case, the direction of movement of the control member between its first and second positions and the direction of movement of the switch body between its first and second positions can, in particular, form a predetermined degree of curvature with each other. This angle is preferably 90. . The switch body of the switch unit can have a pin, and the control unit of the switch unit can have a predetermined recess, wherein the pin of the switch body engages with the recess of the control member, and the control member reaches its second position The switch body is mechanically fixed in its second position. Specifically, the switch body and the control member of the switch unit can be pressed against their respective first positions by spring force, respectively. Furthermore, the disconnecting unit can have a magnetic core in the form of inertia (in the form of ininea, and in the case of the absence of a predetermined breaking condition φ, the magnetic core can be held in a predetermined rest position by means of the spring force. The switch body of the switching unit can have a pin and can form a chute in the control of the switch unit, wherein when the control moves between its first and second positions and in the first and second positions of the switch body When moving between, the pins of the switch body are guided through the chute of the control member. The chute formed in the control member can determine the first and the _ positions of the control member and the first and second positions of the switch body, wherein the switch unit The control member and the respective first and second positions of the switch body are coupled to each other. 201009873 The chute of the switch body in the control unit of the switch unit can determine two rest positions for the pin, the two Corresponding first and second positions of the control member and the switch body of the rest position equivalents. [Embodiment] The following description is illustrated by means of the figures in FIG. 2 and FIG. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 shows a general view of a switching device according to the invention, wherein the switching device comprises a switching unit SE and a disconnecting unit AE. The switching unit SE comprises a switching body 1 on which the switching body is rigidly The button element 2 and the contact bridge carrier 3 are fixed. The contact bridge carrier 3 supports the contact bridge 4' on which the contact element 5 is arranged. The contact element $ has a large number of contact elements (multiple contact elements), The plurality of contact elements are separated from each other by a suitable insulating distance. The contact bridge is electrically connected (electroplated) to connect a large number of contact elements. If the switching unit SE is switched on and thus the switching device is switched on, in a desired manner When the circuit is switched on, the plurality of contact elements 5 arranged on the contact bridge 4 of the switching unit SE are moved in a corresponding manner (downward in FIGS. 1 and 2) such that they are combined with a further plurality of fixed contact elements 6 In contact, the fixed contact element is arranged on a correspondingly fixed contact element carrier 7. Contact (close or connected) of the plurality of contact elements 5 and the fixed contact element 6 In the state, the respective contact elements 5 and 6 are resiliently abutted. The button element 2, the switch body 1, the contact bridge carrier 3 and the 201009873 have contact bridges 4 with a plurality of contact elements 5 arranged thereon which are substantially rigid to each other. In addition, the switching unit SE comprises a control element 8 which is arranged in the switching body 1 of the switching unit SE such that a mechanically effective connection can be formed. The respective longitudinal axes of the switching body 1 of the switching unit SE and the control unit 8 The lines (substantially the axis of symmetry) can form a predetermined angle with each other, said angle being for example preferably 90. At the respective position of the switching body 1 of the switching unit SE and the control element 8 shown in FIG. The preferred angle of the display is shown in which the configuration of the switching unit SE is not so determined. The switching body 1 of the switching unit SE is in its longitudinal direction by means of the first spring 9 in the illustrations in the circles 1 and 2 Prestressed (compressed) upwards, the longitudinal direction being equivalent to the vertical direction in Figs. Further, the control member 8 is prestressed in the longitudinal direction thereof by the second spring 1 ,, wherein the longitudinal direction is a direction toward the left according to the illustration in the drawing. In this embodiment of the switching device according to the invention the 'breaking unit AE is present, for example as an electromagnetic disconnecting unit and comprises at least one magnetic core U, said magnetic core being movably inserted at least in its longitudinal direction relative to the coil 12 A coil 12 (magnetic coil) is inside and guided by a guide 70, not shown. The coil 12 is supplied with electrical energy and, in particular, a current through a corresponding electrical line 13, which generates a magnetic field in the coil 12. FIGS. 1 and 2 show an embodiment with a coil (magnetic coil) and a magnetic core, but it is likewise possible to provide a plurality of coils of the coil 12 or a coil of several partial groups 9 201009873 and can additionally be provided A plurality of magnetic cores composed of a plurality of parts and connected to each other are used as the magnetic core u. The manipulation device 14 is fixedly coupled to the magnetic core u inserted into the coil 12, and the manipulation device moves together with the magnetic core 11 in the longitudinal direction of the magnetic core 11 and the manipulation device 14 when the current is supplied through the electric wire to the coil 12. In order for the magnetic core U to reach a predetermined rest position and thus the actuating device 14 fixedly connected to the magnetic core 11 also reaches a predetermined rest position, a third spring 15 is provided, which is oriented towards the rest position of the magnetic core. A biasing force is applied to the core. According to the illustration of the circle i _ , the biasing force generated by the third spring 15 is directed to the left in the longitudinal direction of the core 丨丨 and the operating device 14 . According to the illustrations in FIGS. 1 and 2, the switch body 1 together with the button element 2, the contact bridge carrier 3, the contact bridge 4 and the plurality of contact elements 5, and the control unit 8 of the switching unit SE also have a disconnecting unit AE. The magnetic core 11 together with the operating device 14 is movable along its own longitudinal axis, with the springs respectively (the first spring 9 and the second spring 10 of the switching unit SE in Figures 1 and 2, and the first of the disconnecting unit AE) The three springs 15) exert a corresponding biasing force on the respective components in the preferred direction. The function and operation of the switching device having the switching unit SE and the disconnecting unit AE are explained below. In the illustration in Fig. 2, the switching unit SE is shown in a configuration in which a plurality of contact elements 5 are in the configuration Separate from the fixed contact element 6 on the fixed contact element carrier 7, via which the plurality of contact elements 5 are arranged on the contact bridge 4 and the contact bridge carrier 3, the switch body 1 and the press 10 201009873: element 2 Form a movable contact. In this case the circuit is disconnected, and in view of the possible movement along its respective longitudinal direction, the switch (along with the button element 2, the contact bridge 3 and the contact bridge 4) and the control member 8 are located correspondingly First position. The first position of the switch body 1 (along with other components 2, 3, 4 and 5 fixed thereto) is at the upper position 'in the illustration in Fig. 2' and the first position of the control member 8 is according to Fig. 2 The icon in the middle is located on the right. ❹ Now if the user presses the switching device and in particular the switching unit SE to open (turn on) the circuit by means of the user pressing the button element 2 of FIG. 2 downwards against the biasing force of the first elastic spring 9, The configuration of the switching body 1 , the button element 2 , the contact bridge carrier 3 and the contact bridge 4 with the associated contact element 5 is then counteracted by the spring force or the biasing force of the first spring $ in the illustration in FIG. 2 . The lower movement 'so that the contact element 5 (movable) is in contact with the fixed contact element #6 and resiliently abuts" in this way switches the circuit in a desired manner, and the switch body i and the other are disposed thereon The component reaches its second position. If, when moving, the button element 2 is manipulated by the user, according to FIG. 2, the switch body 1 is moved from its first position (on the top) to its second position (below), then the biasing force of the second spring 1〇 is 1 and 2 act on the control member 8 in the leftward direction, and the control member 8 is moved from its first position (on the right side in Figs. 1 and 2) to its left position to its second position, which is disposed in the switch unit SE. The pin 1 上 on the control element 8 and projecting from the control element reaches the recess 17 formed on the side of the switch body 1 facing the pin 16 and thus engages the recessed contact 11 201009873 which can accommodate the pin. If the pin 16 of the control member 8 reaches the recess η of the switch body 1 through the corresponding longitudinal movement of the switch body 1 and the control member 8, the lock pin occupies a stable position in the recess 17 so that the switch body is in the In the possible movement of the vertical direction in Figures 1 and 2, the switch body 1 is fixed and held by the engagement of the pin 16 of the control member and the biasing force acting in the left and right of the second spring ι in the figures 2 and 2. . The switch body 1 and the control member 8 are mechanically clamped to each other at a position corresponding to the second position for both members. The switch body 1 and the control member 8 are thus held in their respective second positions by the mechanical engagement of the pin 16 with the recess 17 and the corresponding biasing forces of the first and second springs 9 and 10. By means of this blocking, the switch body and other components arranged thereon, in particular the contact element 5, maintain the position of the jaw against the biasing force of the first spring 9, so that it passes through a plurality of (movable) in a stable manner The contact element 5 and the fixed plurality of contact elements 6 reliably turn on the circuit. If there is a predetermined disconnection condition (de-energization condition for de-energizing the switching device) in terms of the switching device and in particular in the disconnecting unit AE, this is recognized by the evaluation device and the control device (not shown). The corresponding current of the coil 12 of the disconnecting unit AE is then supplied via the electric line 13 so that the coil 12 can form a corresponding magnetic field which acts directly on the magnetic core 11 and thus also on the actuating device 14. If a magnetic field is formed by the coil 12 together with the power supply, the magnetic core u (the operating device 14 fixed to the magnetic core 11) starts to oppose the biasing force of the third spring 12 201009873 15 in the figure! In the illustrations in and 2, the direction moves to the right in the direction of the control member 8. If at this point the control member 8 and the switch body 1 are in their respective second positions, as shown in Figure 1 and wherein the pins 16 of the control member 8 are correspondingly open (four)! The groove 17 provided therein is in contact, and the material 11 and the operating device 14 mounted on the magnetic core U are in their rest positions due to the biasing force of the third spring 15 (on the leftmost side in the illustration of FIG. i) Then, there is a predetermined distance D between the right end of the operating device 14 and the left end of the control member 8, the operating device 14 and the control member 8 lie on a common straight line in their longitudinal direction and can follow this straight line mobile. °

If, according to the above description, the magnetic core 11 is moved to the right according to the illustration in FIG. 1 by means of the magnetic field generated by the coil 12, and thus the operating device 14 is moved to the right in the same manner, the interconnected components (magnetic core) 11 and the actuating device 14) produce an acceleration along the predetermined distance D in the direction of the control member 8. This means that during the movement of the predetermined distance D, the magnetic core U and the actuating device 14 are accelerated by the force exerted by the magnetic field and thus absorb the kinetic energy, so that the magnetic core 11 of the disconnecting unit ae together with the actuating device 14 overcomes the advance After the determined distance D, it hits the left end of the control member 8 and creates a collision on the control member 8. The substantially elastic collision with the kinetic energy predetermined by the geometry of the 7G piece involved is related to the material used 'so that the kinetic energy stored during the acceleration of the magnetic core 11 together with the actuating device 14 over a predetermined distance D is almost completely It is transmitted to the control member 8, which is now at its second 13 201009873 position (on the left in Figures 1 and 2) and is thus in a locked state with the switch body i by the pin 16 and the recess 17. The switch body i is also in its first position (below in Figures 1 and 2, the circuit is turned on). If the magnetic core 11 together with the actuating device 14 produces a (primarily elastic) collision on the control member 8 by means of a predetermined kinetic energy, then the control member 8 is biased against the second spring 1 ( (in FIGS. 1 and 2). The medium biasing direction is moved to the left or to the right, so that the pin 16 of the kinetic energy control member 8 that is transmitted to the control member 8 through the core u of the breaking unit AE and the operating device 14 can be separated from the control member 8 The position in the recess 17 of the switch body 1 is then fixed, and then the control member 8 is moved to the right in the direction of its first position in accordance with the illustration in the circle. Since the movement of the control member 8 and the switch body is opened by the movement of the control member 8 by the magnetic core u of the disconnecting unit AE and the steering device Μ rightward, the mechanical barrier is passed through the first-elastic yellow 9 The force, the switch body 1 together with the contact bridge 4, the plurality of contact elements 5, the contact bridge carrier 3 and the button element 2 are not moved upwards according to the + + A ^ r in the circles 1 and 2, so that a plurality (movable) The contact element 5 is no longer in contact with the correcting one and touches the plurality of fixed contact elements 6 and thus opens the circuit. Therefore, the switch avoidance switch body 1 reoccupies its first position (the knife switch is simple) on the other components disposed thereon, wherein the control member 8 also reaches its first position (in the force 1 position (in Figure 1 and 2 in the right side) and in this position the pin 16 of the control member 8 is tightly sinned by the biasing force of the second spring 10 on the side of the switch body 1 (Fig. 2). After a collision occurs on the control element 8 of the switch unit 7G SE, the cutting device cuts off the supply of the line 12 of the disconnection unit 2010 201009873 and cuts off the resulting magnetic field of the magnetic core 1 and thus likewise the control device 14 By returning to the rest position (original position) by the biasing force of the = ^ / dyke spring 15, the rest position is located on the left side according to the illustration in Figures 1 and 2. In this way, the lock is stable. State and open state

The closing unit SE is disengaged and thus disconnected. The circuit is disconnected. The control member S and the switch body 1 return to their respective first positions. Specifically, open

The control member 8 and the switch body 1 that are stipulated by the door 70 thus have respective first and second positions. The first and second positions are coupled to each other and can be mutually reached by relative movement. By a predetermined distance D between the actuating device 14 of the disconnecting unit AE and the control unit 8 of the switching unit SE, it is possible to reduce the structural size and the reduced weight even for smaller power and time. In the (determined size) disconnection "E", it is also ensured to be reliably switched on or off, since in the weaker magnetic field of the coil 12, the disconnection of the unit AE in order to open the switching unit SE can also pass a predetermined distance.产生 A sufficiently large collision occurs on the control member 8 of the switching unit SE. When the magnetic core 11 moves through the predetermined distance D during the formation of the magnetic field in the coil 12, it is reached during the period of the predetermined distance D. Acceleration enables the storage of predetermined kinetic energy by the magnetic core U together with the actuating device 14 so as to ensure an effective and reliable disconnection or de-energization. The control of the switching unit SE is carried out by the combination of the magnetic core 11 and the actuating device 14 in motion. Almost all of the 8 is an elastic collision, and all the kinetic energy absorbed from the acceleration of the components 11 and 14 is transmitted to the control member 8, 15, "201009873 makes the biasing force against the second spring ι〇 and Although the pin 16 of the control member 8 has a stable position in the recess 17 of the switch body 1 of the switch unit SE (second position), it can also be disengaged and thus the control member 8 can be moved from its second position to its A position (disconnect circuit, shown in Figure 2). In order to move at least a predetermined distance, the magnetic core 11 is preferably in the form of inertial mass. Since the breaking unit AE with the magnetic core 11 having the function of the lifting magnet is arranged such that there is a predetermined distance D between the operating device 14 and the control member 8, when the magnetic core 11 starts moving, only the magnetic core 丨The inertial mass of i including the manipulating device 14 must be accelerated by the magnetic field formed within the coil 12 such that the total volume (inertial mass) of the core 11 and the handling device 14 is stored over a predetermined distance travel path. The (predetermined) kinetic energy enables the control member 8 to be disengaged from its stable second reference 4, which is equivalent to the rest position, so that the switch body 1 can then also return from its second position to its first position (right figure) 1 and 2 are above), thereby breaking the circuit. The payout arrows in Figures 1 and 2 indicate the movement of the various components (switch body 1, control 8 and core 11 with grip E τ ^., device 14). And 2 and especially the switch unit SE is disconnected, according to the switch off-circuit condition (power-off condition). Therefore, in particular, when the state of the disconnection is determined, it is necessary to determine whether or not there is a pre-determined disconnection condition for the purpose of breaking H°. The coil 12 is powered by the wire 13. 'Can be a predetermined fault condition, overcurrent, 201009873 overvoltage or a condition such as ιΗ_#, where after the defective condition is detected, the coil 12 of the tripping AE is disconnected to provide a corresponding current for disconnection The switch is single-turned so that this corresponding current can have the function of an open signal (AUS, 5), and the switching device is used as a protective switch. In the case of a domestic appliance, the switchgear can also be provided with a switching device SE and a disconnecting unit AE according to the invention, for example a washing machine or a dryer, wherein after being switched on, the user presses a button 70 of the switching device. 2 The circuit can be switched on and thus the device is switched on. If the operation is terminated or the determined measures are terminated in accordance with a predetermined operating sequence of the device, then the switching device with the switching unit SE can be switched off in an automatic manner and thus the supply of power to the device can be cut off. In the construction of the switching device according to the invention in a domestic appliance, for example in a washing machine or a dryer, it is possible to provide a small-sized and thus low-cost break by the configuration with a predetermined distance D specified above. The unit AE is opened, which can also result in an effective disconnection and thus a reliable shutdown of the device. Advantageously, this allows the entire switching device to have a smaller size β. If the device is completely turned off without regard to the presence of a disconnection condition (power-off condition) from the user's side, then other switching mechanisms can be provided as well. By means of the switching mechanism, the coil 12 of the disconnecting unit 供电 is supplied with power in a predetermined manner after manual actuation by the user, so that in the case of switching on the device (switch body 1 and control unit) In their respective second positions, the possibility of automatic power-off in addition to the above can also be carried out by manual manipulation by the user. 17 201009873 Therefore, in principle, in the case of acceleration (power supply by the coil 12), the pulse size is received on the route of the magnetic core 11 and the steering device 14 in the direction of the control member 8 over a predetermined distance D. The pulse size or pulse power is produced by means of a collision on the control element g by the actuating device 14, which is used together to accelerate the magnetic core! And a route of at least a predetermined distance D of the operating device 14, provided with a small amount of electrical energy (current) for disconnecting the coil 12 of the unit AE. The electrical energy or the power supply for disconnecting the coil 12 of the I 兀 AE can, in particular, continue to predetermine the time _ when the magnetic 4 11 and the operating device 14 have stored at least a predetermined distance D during the acceleration of the at least predetermined distance D An effective and reliable disconnection (power down) of the switch unit SE. In the absence of current, that is to say in the case of a power-off of the coil 12 of the disconnecting unit AE, due to the biasing force of the spring 15, the magnetic core u is returned to it together with the operating device 14 (set on the left in Fig. 1) Position). In the illustrations in Figures 1 and 2, a single 7° SE monopole is constructed in order to create a connection or a split _ ’ switch in the circuit. However, the switching device with the switching unit SE according to the invention can also be embodied in multiple poles and is therefore used for a large number of circuits, such as the control unit 8, the switching body 1 and the magnetic core 11 (along with corresponding other components arranged thereon). The course of movement of the respective movable part is guided linearly and by a corresponding stop limit, however, the stop is not shown for the sake of simplicity in the figures in FIGS. 1 and 2 . Compared to the solutions known from the prior art, it is not necessary within the scope of the invention to apply a large force when the magnetic core u starts to move (along with the operating device Μ) 18 201009873, which force is required in the following cases When the predetermined distance is not provided between the control unit 8 of the switching unit SE and the operating device 14 of the disconnecting unit AE, the operating device 14 is also in close contact with the control unit 8 in the stationary state and The control member 8 must also be immediately accelerated when the movement of the disconnection process begins. Thus, according to the invention, only a small force is applied by means of the disconnection unit AE together with the coil 12 and the current supplied to this coil 12, said force being able to cause the magnetic core 11 of the disconnecting unit AE and during the acceleration over a predetermined distance D The manipulating device 14 obtains sufficient kinetic energy for performing the disconnection process. Therefore, direct acceleration is applied only to the core Π and the operating device 14 of the disconnecting unit AE. The above-described switching device having the switching unit SE and the disconnecting unit AE can also be used together with the standby state control device (standby control device). In this case, the disconnection criterion can be defined by the standby state control means, and then the switching means is opened in the above manner based on the disconnection criterion. In particular, it is possible to automatically transition from a standby state with low power consumption to a state of no current, for example according to a waiting time in which a disconnection condition (power failure criterion) is present or satisfied after a waiting time elapses, so that The switching device is automatically disconnected and the device then switches to a currentless state. In addition, when the program is terminated or when it is required to automatically disconnect (power off) in the case of detecting the determined operating state of the computer or the device to be monitored or to be controlled, 'can also be combined with computer equipment (computer data processing, personal computer) , host computer, server, and the like, to generate a disconnect condition. It is possible to reliably disconnect by means of the above-described switching device with a disconnected power supply having a lower power. 201009873 A second embodiment of the present invention will now be described with reference to Figs. * If the corresponding material basic fields are the same (4), then the components of the switching device having the switching unit and the disconnecting unit are shown in Figures 3 and 4 by the same reference numerals as in Figures 1 and 2t. Fig. 3 is a schematic view showing the apparatus of the second embodiment having the switching unit squeezing and disconnecting unit AE (four) closing means. In the same manner as in the first embodiment, the switch single it SE includes the switch body! The button member 2, which can be manipulated by the user (operated by the lower (four) lower operating member 2), is disposed in the area of the top of the open body. The contact bridge 4 is directly connected to the switch body i (different from the structure in Figs. 1 and 2) which supports the plurality of contact elements 5 in the same manner as in the first embodiment. The plurality of contact elements 5 which are regarded as movable contact elements are brought into contact with the fixed contact element 6 when the switching device is switched on and in particular when the switching unit SE is switched on, the fixed contact element being fastened to the contact element carrier. 7 on. Figure 3 shows the state of the switching unit when the circuit is switched on and thus the plurality of contact elements $ and ❹ 6 are switched on. In the switch body 1 in a similar manner to the first embodiment, a control member 8 is provided in the second embodiment, and the control member is in effective contact with the switch body 1 in the following configuration. As in the first embodiment, the switch body 1 and the control member 8 can be moved relative to each other. Specifically, the switch 鳢! The movement can be extended in its longitudinal direction, wherein the switch body is extended in the vertical direction according to Figs. For this purpose, the control member 8 can be moved relative to one another in a predetermined manner, wherein the switch body 1 and the control member 8 are preferably moved relative to each other substantially perpendicularly to 20 201009873. The control element 8 and the switching body 1 are guided in a corresponding manner by mechanical elements, not shown, so that the two parts can be moved back and forth (sliding). A biasing force in the upward direction (in Fig. 3) is applied to the switch body 1 by the first spring 9.

The breaking unit AE according to the second embodiment also includes a magnetic core 设置 disposed in the coil 12 and in the form of inertial mass, and an operating device fixedly disposed thereon or integrally formed with the magnetic core u . The coil 12 can be powered or powered by wires such that the coil 12 can generate a corresponding magnetic field for manipulating the core u.

On the side of the magnetic core 11 with respect to the side of the operating device 14, the magnetic core U tapers transversely to its direction of movement (acting direction) and supports the third spring 15' by means of said third spring magnetic The core U occupies the coil 12 without current (no magnetic field) occupies a predetermined rest position (the position 'as the other disconnecting unit AE of the function of the unit AE of the disconnecting unit of the embodiment shown in Fig. 3 The mode of operation is the same as that of the first mode of operation'. It is possible to omit the description of the disconnection. The role of the SE is explained below with respect to the switching unit mode according to the second embodiment. Each of the τ parent parts can occupy the second position. The starting unit SE is in the following description. The starting point is that the first state of 21 201009873 is opened, where the switch body 1 and the control member 8 are located in their respective The movable plurality of contact elements 5 which are positioned and arranged on the electrically conductive contact bridge 4 are not in contact with the fixed plurality of contact elements 6 and thus open the circuit. Unlike the first embodiment, The workpiece 8 has a chute arranged in a predetermined manner in the region near the switch body i, which can influence the position and movement of the switch body 1 (vertical movement in Figures 3 and 4). In the region of the configuration of the chute K, the switch body 1 has a pin S' in which the pin s moves within a predetermined chute κ when the control member 8 and the switch body 1 are relatively moved back and forth relative to one another. Is the chute K defined at the end of the relative movement between the control member 8 and the switch body 1 and further defines two stable rest points, wherein the first point P1 is disposed at the upper end of the chute K. If the switch body 1 and The control members 8 are in such a position relative to each other relative to each other such that the pin S of the switch body 1 occupies the point P1, then the switch body i and the control member 8 are in their respective first positions. The chute κ ^ in 8 is also referred to as a heart-shaped curve. The electrical contact points or the moving and fixed contact elements 5 and 6 are disconnected at this position and thus the circuit is broken. If the user now intends to operate the switching device and In particular, the switch unit SE' is actuated, whereby the user applies pressure on the button element 2 and presses the button element 2 and the (fixedly connected) switch body arranged thereon (down according to FIGS. 3 and 4' In this case, the switch body 1 mounted by the support not shown and guided in its movement moves downwards 22 201009873, so that the switch body 1 is too point P2 of the pin face in the chute κ, wherein Corresponding to this downward movement to the next, absolutely moving, through the guidance of the station chute K, the control 4 of the nail S is moved back and forth transversely to the switch by means of the flashing brush 8. The movement of the body 1 is light if When the pin S of the switch body arrives, the point P2 of the lunar channel K is used. ^ The pin s of the switch body 1 is slipped to reach the point P4 by the biasing force of the first bullet 9, wherein the point p4 倌円

A stable static point in the distribution of the lunar channel K. By the pin s, a reverse glue is applied to the switch body 1 and the control member 8 to reach the corresponding second position. If the user intends to open the circuit again ' then this requires re-manipulating or re-pressing the button element 2 and thus pressing the switch body down, so that the pin S of the switch body 1 moves down within the chute κ of the control member 8 to Point 3' and then after the release of the button element 2 by the user, the pin s moves up in the chute κ up to the point '5' and the point at the beginning of the motion cycle due to the biasing force by the first spring 9. Ρι is the same. When the pin S of the switch invitation 1 moves in the chute κ provided in the control member 8, the switch body 1 moves in synchronization with the pin S in its longitudinal direction (in the vertical direction in the circles 3 and 4). The control member 8 is limited by the extent of the back and forth movement determined by the chute κ. This is indicated in Figures 3 and 4 by arrows for respective relative movements. The point P4 in the path defined by the chute K is a stable position which indicates a corresponding second position 'for the switch body 1 and the control member 8 and the same point P1 as the point P5 for the switch body 1 and The control member 23 201009873 8 indicates the corresponding first position. In the respective first position, the contact is broken and thus the circuit is switched off. However, in the respective second position, the plurality of contact elements 5 and 6 are switched on and thus the circuit is switched on. Therefore, according to the configurations of FIGS. 3 and 4 of the switching device of the second embodiment, it is possible that the user can manually adjust the respective switching devices by re-manipulating (pressing down) the button member 2 after opening or closing the switching device. The opposite operating state.

The disconnection of the switching device and in particular the opening of the switching unit SE by the disconnecting unit AE will be explained below. When the control member 8 is in the second position in the same manner as in the first embodiment, and in the disconnecting unit AE #still state, the operating device 14 disposed on or integrally with the magnetic core 11 is The outer end of the actuating device 14 has a predetermined distance d from the control material 8. a state in which the opening 1 and the control member 8 are located at their respective second positions, in which the pin S of the switch body 1 is at the point Ρ 4 of the stencil, and If according to the disconnection bar, the presence of this ηβ, (breaking or power-off criterion) is supplied to the coil 12 by the electric wire 13 or the current is then '', according to the figures in Figs. 3 and 4, the biasing force of the core U is connected The rightward shifting device 14 is started against the control member 8 which passes through the third spring 15D and touches # (the main IB, U at least overcomes a predetermined distance 胥疋 elasticity). Therefore, the magnetic core 11 together with the operating device 24 during the movement of the magnetic core 11 toward the control member 8 in a direction along a predetermined distance D in the same manner as in the first and the operating device 14 201009873 14 absorbs kinetic energy by a magnetic field formed in the coil 12 such that when moving in the direction of the control member 8 after overcoming the predetermined distance D, the manipulation device U absorbs such (pre-cut) kinetic energy so that it is sufficient A collision occurs on the control member 8 so that the control member 8 is slightly moved to the right according to the illustrations in FIGS. 3 and 4, so that the pin s of the switch body t no longer abuts stably against the point P4 of the chute K, but In the chute κ, it moves or slides to the left from the point Ρ 4. Therefore, the switch body! is no longer held in its second position by the control member 8 together with the pin S and the chute 。.

The switch body 1 is moved upward by the biasing force of the first spring 9, so that the pin S of the switch body 1 is moved upward in the chute κ of the control member 8 to the point Ρ5 or Ρ1. In this movement of the collision (mainly elastic) on the control member 8 by the breaking unit αε, the plurality of contact elements 5 and 6 previously in contact are separated from each other and thus the circuit is broken. With the configuration shown in FIGS. 3 and 4 of the switching device according to the second embodiment and described above, in the same way as in the first embodiment, a reliable disconnection of the switching device is ensured (power-off) In the case of a disconnected unit having a small size, sufficient kinetic energy can be obtained by the configuration of the magnetic core 11 in the form of inertial mass and a predetermined distance D between the operating device 14 and the control member 8 in order to ensure Reliable disconnection. As described above, in addition to the possibility of switching on the switching device and opening the switching device by means of the disconnecting unit, the user can also directly perform the closing manually by means of the configuration according to the second embodiment. The predetermined breaking condition is the same as the breaking condition as in the first embodiment, wherein in this case it is also possible to use it in industrial fields or household appliances 25 201009873, for example in a washing machine or dryer. By means of the disconnection of the disconnecting unit AE, it is likewise possible to transition from a standby state of the device with very little power consumption in some cases to a completely currentless state of the device (complete power down). By detecting the presence of the disconnection condition and supplying the corresponding current to the coil 12 of the disconnecting unit AE, the disconnecting unit AE of the switching device according to the invention can also be actuated by means of a control device or a controller of the personal computer. Advantages achieved by the configuration of the switching device according to the second embodiment ® are the same as those of the first embodiment.
