Definitions

  • the invention relates to a button for performing safety-related switching processes with at least two mechanically decoupled switching elements that can be actuated jointly by manual actuation of an actuating member.
  • key or "key switch” is understood here to mean an electrical switching device, the contact position of which, when operated manually, changes from an idle state to an actuated state, the idle state automatically being resumed as soon as the manual actuation ceases.
  • the manual actuation of such a button is usually carried out by exerting a mechanical force, in particular pressure force.
  • Two switching elements are referred to as mechanically decoupled if the function of one switching element is independent of the operating state of the other switching element.
  • Two switching elements are designated as jointly operable if, by means of a single manual actuation process, it is possible to transfer both switching elements into their respective actuated states. The switching of the individual switching elements can take place simultaneously or at different times.
  • the jamming of a mechanical button can be caused by material defects, penetrating dirt particles and corrosion, but also by deliberate manipulation, e.g. to circumvent security measures that are perceived as annoying. The greatest possible manipulation is therefore very important for a button provided for security-relevant applications.
  • redundant signal generation In order to be able to safely process signals generated using mechanical keys, redundant signal generation is often required.
  • a safe, but technically complex, method for redundant data generation consists in providing several separate buttons that are to be operated simultaneously for signal generation.
  • a button with two switching elements assigned to a common actuating element is known, in which the latter problem is avoided by mechanical decoupling of the two switching elements.
  • the Mechanical decoupling is achieved in that only one switching element is designed as a mechanical switch, while the second switching element is an electro-sensory switch.
  • the electro-sensory partial function of the button remains functional even if the switching mechanism is jammed.
  • a button designed to generate safety-related signals should be suitable for performing a so-called jog mode.
  • Jog mode is particularly necessary when adjusting and setting up systems as part of commissioning. In preparation for the actuation, an operator places his finger on the button head and, if necessary, partially presses it through, but only overcomes the actuating force required to trigger the control signal for a short time or at intervals.
  • the invention has for its object to provide a structurally simple key that is suitable for generating safety-related switching processes and allows easy handling.
  • the key comprises two mechanically decoupled switching elements which can be actuated jointly via an actuating member, a first switching element in the actuated state interrupting a signal path which is closed in an idle state and one which is open in the idle state Activated signal path.
  • Another switching element is arranged in the signal path which is open in the idle state and enables it in the actuated state.
  • the signal path closed in the idle state is referred to below as the NC (normally closed) path, a closed signal path being understood to mean an uninterrupted and therefore electrically conductive current path.
  • NO normally open
  • NO is correspondingly open signal path in idle state not conductive in idle state.
  • the interconnection of the two switching elements according to the invention enables the safe generation of signals in a particularly simple manner.
  • the key is protected redundantly in that a correct generation of a control signal is only possible when both switching elements are functioning, and in the course of the actuation process, a signal change takes place both in the NC path and in the NO path.
  • At least a minimum function of the key can also be monitored in the idle state using the NC path that always carries the signal in the idle state. A short circuit or a line interruption in the key or the connected line system is detected, for example, on the basis of an irregular signal loss in the NC path.
  • the first switching element preferably has a snap switching behavior.
  • the switching of the first switching element takes place suddenly and inevitably within a short period of time, regardless of the time course of the actuation pressure.
  • the two switching elements are expediently designed such that the actuating force to be applied to actuate the first switching element significantly exceeds the actuating force to be applied to actuate the second switching element. In particular, this improves the tactile switching behavior of the key by having a user Actuation of the first switching element and thus for the final triggering of the switching process must overcome a clearly noticeable pressure point. This particularly facilitates the handling of the key in jog mode.
  • the second switching element is a long-stroke pushbutton switch, i.e. designed as a push button switch with a comparatively large actuation path on the order of several millimeters.
  • a long-stroke pushbutton switch as it is already used in many cases in control devices of machines as a command device, is characterized by a high level of operating convenience, if only because of its comparatively large dimensions.
  • the first switching element comprises a preferably approximately cylindrical button head as an actuating member, which is guided in a button holder so as to be displaceable against the restoring force of a spring device.
  • the mechanical decoupling of the first from the second switching element can be implemented in a particularly advantageous manner by integrating the first switching element in the key head, so that the first switching element can still be actuated even when the key head is jammed in the key holder.
  • the first switching element is expediently designed as a short-stroke key switch.
  • a short-stroke switch that is, a key switch which is characterized by a comparatively small actuation path of preferably less than 1 mm, is available in multiple embodiments and is often used in a high-quality key panel, for example in an automated teller machine.
  • a conventional short-stroke key switch is extremely compact and is therefore particularly suitable for installation in the key head of a long-stroke key switch.
  • a high-quality short-stroke key switch is characterized by extremely high operational reliability, ie extremely low susceptibility to errors.
  • the first switching element is designed as a membrane key switch.
  • a membrane key switch which is also often used in machine controls as part of a membrane keyboard
  • the tactile area adjacent to an operator interface is covered by a flexible front foil.
  • Such a push button switch is operated by manually exerting pressure on the front film.
  • the first switching element is held in its idle state under the action of a magnetic force.
  • the switch contact is torn off from the holding magnet, whereby the restoring magnetic force is suddenly reduced, and the switch contact jumps into its actuation position.
  • the first switching element contains a snap element for generating a snap switching behavior.
  • Such a snap element is designed, for example, as a metallic snap disk, as is known in principle from a so-called "snap frog".
  • the first switching element can also be implemented in what is known as "switching bubble” technology.
  • the switching element contains a front film provided with a bubble-like embossing in the tactile area. This "switching bubble” is used to operate the Switching element pressed in and jumps back into the pre-shaped shape when the actuation pressure decreases.
  • the resetting of the second switching element designed as a long-stroke pushbutton spring device comprises at least two spring elements of different lengths, which are clamped between the moving button head and a stationary stop when the button head is displaced along its actuation path.
  • a spring device is also referred to as a progressive spring system, especially since only the comparatively long spring elements counteract the movement of the key head at the start of the actuation process, and the restoring force is therefore comparatively low. Only when the so-called working point or contact point of the second switching element is reached does at least one further, short spring element come under pretension, as a result of which the counterforce exerted by the button head increases suddenly and indicates to the user that the working point has been reached.
  • at least one spring element is simultaneously provided as an electrical contactor and provides electrical contact between the key holder and the key head.
  • the progressive spring system described here is particularly advantageous to use as a switch contact.
  • Accidental triggering of the key is effectively excluded by a rigid front ring which surrounds the key head and which extends preferably beyond the user interface surrounding the key and in which the key head is completely immersed in the idle state.
  • An embodiment of the invention serves the same purpose, according to which the actuation path of the key head is several millimeters, preferably 3-6 mm.
  • the advantages achieved with the invention are, in particular, that the ease of use and the handling safety a long-stroke key switch on the one hand and the low susceptibility to errors and the manipulation security of a short-stroke key switch on the other hand are combined.
  • the key according to the invention enables, in a structurally particularly simple manner, the redundant signal generation required for safety reasons and reliable error detection, which in particular can also be carried out in a slightly automated manner. Incorrect switching due to jamming, getting stuck, stiffness of the button head or improper operation or even deliberate manipulation are largely excluded due to the design.
  • the key 1 shown in its idle state in FIG. 1 comprises two interconnected switching elements 2 and 3.
  • the first switching element 2 is implemented in a commercially available short-stroke technology and, in the manner of a two-way switch, exhibits a discrete, in particular erratic switching behavior between two switching states.
  • a suitable short-stroke key switch is known, for example, under the brand name "PushGate" (from Duraswitch Industries Inc.).
  • PushGate from Duraswitch Industries Inc.
  • the signal input 4 is with the NO output 6 conductively connected, while the connection between the signal input 4 and the NC output 5 is interrupted.
  • the change of state from the idle state to the actuated state is triggered in a manner not shown by exerting pressure on an actuation button 7 of the switching element 2, which is only indicated.
  • the second switching element 3 is designed as a long-stroke key switch, as it is already widely used for example for control functions of industrial machine tools.
  • the second switching element 3 comprises a key head 10, which is displaceable against the restoring force of a spring device 8 in an approximately hollow cylindrical key holder 9 have a greater length than the central spring element 12.
  • Each spring element 11, 12, 13 is fixed at the end to the key head 10 and guided in a spring guide 14 flanking the spring element 11, 12, 13.
  • the spring guide 14 is designed, for example, in the form of tubes which are molded on the inside of the key head 10 and in which the spring elements 11, 12, 13 lie.
  • a contact foot 15, which closes the key holder 9 to an installation side 16, serves as an abutment for the spring elements 11, 12, 13.
  • the contact foot 15 comprises a contact carrier 17, which is inserted in the manner of a cover into the end face 18 of the key holder 9 facing the installation side 16.
  • the contact carrier 17 is locked on the key holder 9 with latching elements 19 engaging in the key holder 9.
  • An O-ring 21 or the like inserted between the contact carrier 17 and the inner wall 20 of the key holder 9 seals the interior 22 of the key 1 from the installation side 16.
  • each contact pin 23, 24, 25 is fixed, which protrude into the interior 22 of the key 1 and each serve as an abutment for one of the spring elements 11, 12, 13.
  • Each contact pin 23, 24, 25 is connected through the contact carrier 17 to a screw terminal 26, 27 or 28 accessible from the installation side 16.
  • Each contact pin 23, 24, 25 is further provided with a tapered head 29 which cooperates with a locking projection 30 of the spring guide 14 to form a locking of the key head 10 which can be overcome by exerting pressure in its idle state.
  • Each contact pin 23, 24, 25 dips into the spring guide 14 and serves as an abutment for the corresponding spring element 11, 12, 13 lying therein.
  • the long spring elements 11 and 13 are pretensioned between the respective contact pin 23, 24, 25 and the key top 10, so that the key top 10 is biased in the direction of the operating side 31 opposite the installation side 16.
  • the key head 10 is in this case held in its idle state by locking hooks 32 cooperating with the key holder 9 against the bias of the spring elements 11 and 13.
  • the spring element 12 lies relaxed in the spring guide 14, a distance being formed between the spring element 12 and the corresponding contact pin 24.
  • a front ring 34 connected to the key holder 9 on a shaft area 33 from the operating side 31 serves to fasten the key 1 to the front plate 35 of an operating element or control panel (not shown in more detail).
  • the front plate 35 thus separates the operating side 31 from the installation side 16 which is not accessible to the operator.
  • the button 1 only projects beyond the front plate 35 with a head region 36 of the front ring 34 widened relative to the shaft region 33 to the operating side 31.
  • the key holder 9, on the other hand, is located on the inaccessible installation side 16.
  • the head region 36 of the front ring 34 is designed such that it completely takes in the key head 10 in the idle state. In other words, the key top 10 does not protrude beyond the head region 36, so that the risk of inadvertent actuation of the key top 10 is reduced.
  • a sealing ring 37 is inserted, which has a V-shaped profile that is open toward the operating side 31.
  • the sealing ring 37 thus acts in the manner of a moisture wiper and prevents the penetration of both vaporous and condensed moisture from the operating side 31 into the interior 22.
  • An additional sealing ring 38 arranged between the front ring 34 and the front plate 35 prevents moisture from penetrating the latter Connection point additionally prevented.
  • the first switching element 2 which is extremely compact due to its short-stroke design in comparison to the switching element 3, is now arranged within the key top 10 in such a way that its actuating button 7 rests directly on the pressure surface 39 of the key top 10 adjacent to the operating side 31.
  • the first switching element 2 also borders directly on the spring device 8, so that the spring element 11 is electrically conductively contacted with the signal input 4, while the NO output 6 is contacted with the spring element 12 and the NC output 5 is connected to the spring element 13 is.
  • NC signal path 40 which, starting from the screw terminal 26 via the contact pin 23, the spring element 11, the signal input 4, the NC output 5, the spring element 13 and the contact pin 25 to the screw terminal 28 leads.
  • NO signal path 41 Another line connection, hereinafter referred to as NO signal path 41, which leads from the screw terminal 26 via the contact pin 23, the spring element 11, the signal input 4, the NO output 6, the spring element 12 and the contact pin 24 to the screw terminal 27, is in the idle state both within the switching element 2 and within the switching element 3, more precisely between the spring element 12 and the contact pin 24, interrupted.
  • the actuation state of the button 1 can thus be determined at any time.
  • the actuation of the key 1 takes place with respect to both switching elements 2 and 3 by manually pressurizing the key head 10 in the area of its pressure surface 39.
  • the key head 10 thus serves as a common actuating element for both switching elements 2 and 3, with which the switching elements 2 and 3 together, i.e. can be operated in a single operation.
  • the switching element 3 is actuated, as shown in FIG. 2, by shifting the key head 10 from the idle state in the direction of the installation side 16, the switching process being brought about by the spring element 12 coming into contact with the contact pin 24 and thus a conductive connection between the NO output 6 and the screw terminal 27.
  • the switching element 2 is actuated, as shown in FIG. 3, in that the actuating button 7 is pressurized through the pressure surface 39.
  • the pressure surface 39 is formed as a flexible front film consisting of a plastic or elastomer material, which is elastically deformable when pressurized.
  • the bendability of the pressure surface 39 is additionally increased by an annular groove 42 provided on the inside in the pressure surface 39 as a predetermined bending point.
  • the switching elements 2 and 3 are designed in such a way that a lower force is required to actuate the switching element 3 than to actuate the switching element 2.
  • the button 1 When the button 1 is actuated, the one which is due to the latching must first the locking projections 30 on the respective head 29 of the contact pins 23, 24, 25 caused pressure point are overcome.
  • This pressure point which is provided to improve the tactile switching feeling of an operator, is chosen so low that the force required to overcome it is not sufficient to actuate the switching element 2.
  • pressure is further applied to the button head 10 with a comparatively low actuating force F1
  • the button head 10 is moved in the direction of the installation side 16 until the actuation path s1 of the switching element 3 has been covered and the spring element 12 contacts the contact pin 24.
  • the actuation path s1 is preferably 3-6 mm.
  • the position of the key 1 shown in FIG. 2, in which the switching element 2 is still in its idle state, but the switching element 3 is already actuated, is referred to as the partially actuated state or operating point of the key 1.
  • the NO signal path 41 is enabled by the switching element 3, but the signal state which can be tapped at the screw terminals 27, 28 is unchanged from the idle state due to the unchanged position of the switching element 2.
  • the key top 10 can be moved beyond the operating point.
  • an actuating force F2 which is higher than the actuating force F1 is required for this.
  • This actuation force F2 shown in FIG. 3 is so great that the switching element 2 is now also actuated and also releases the NO signal path 41.
  • there is a sudden change in the signal of the two signal paths 40 and 41 as a result of which the input signal applied to the screw terminal can now be tapped at the screw terminal 27, while a zero signal is present at the screw terminal 28.
  • the actuating element 2 When the pressurization decreases under the actuating force F2, the actuating element 2 first jumps to the idle state back, whereby again an approximately simultaneous and inverse signal jump occurs in both signal paths 40 and 41. If the pressurization is further reduced, the switching element 3 also opens, the key 1 again going into the idle state shown in FIG.
  • buttons 1 can e.g. can be recognized by a control and monitoring unit by the fact that, in stationary operating states, a signal which is inverse in the binary sense is always present in the NC signal path 40 and in the NO signal path 41. With a proper switching process, the signal in both signal paths 40 and 41 changes suddenly and approximately simultaneously within a switching time that is on the order of a few milliseconds.
  • the jamming of the button head 10 when the button 1 is released is a source of danger which is difficult to control, especially since the button is the operating request corresponding control signal continues to be generated undiminished.
  • this source of danger is eliminated, especially since the switching element 2 springs back into the idle state even when the button head 10 is jammed, thus signaling a proper end of the operating request.
  • This counteracts in particular the possibility of deliberate manipulation of the key 1, for example by deliberately jamming the key top 10. Because of the smooth surface of the pressure surface 39 and the comparatively high actuating force F2 required to actuate the switching element 2, the key 1 is extremely difficult to manipulate.
  • the key 1 also enables a simple tap operation. Jog mode is particularly necessary when adjusting and setting up systems as part of commissioning. Here, an operator can put his finger on the button head 10 and push it through to the working point, but only apply the actuating force F2 required for actuating the switching element 2 for a short time and at intervals. Especially since the button 1 the switching time is determined exclusively by the actuation time of the switching element 2, but not after how long the switching element 3 has been actuated at this time, such a jog mode does not lead to an irregular operating state.
