Definitions
- the invention relates to switches for electrical contacts.
- the invention relates to switches for manually switching electrical contacts.
- Controls such as switches or regulators should be easy to switch, but at the same time give the user during the switching process the feeling that the switch and thus an electrical contact has been brought into the desired position, including the one hand, the mechanical feeling in the operation of the switch and the other hand connected noises are of great importance.
- the switches should function safely over long periods of time in a variety of climatic conditions.
- Conventional switches provide locking mechanisms in which a switching element, which is mechanically connected to a control element, can engage in one or more detents. Each of the notches corresponds to a switch position.
- the switching element has contacts which produce the necessary electrical contacts for the switching function in the respective position.
- the switching element is acted upon by spring force, by means of screw or leaf springs, towards the notches, so that the switching element engages in the notch when it is brought into the vicinity.
- the movement of the switching element takes place by means of an operating element which is mechanically connected to the switching element directly or via levers and joints.
- the control is typically mounted on the control panel or dashboard of the device so that it can be easily operated by a user.
- the mechanical connection of the control element with the contact or switching element has the disadvantage that for mechanical movements of the elements openings must be provided in the switch, whereby dirt and moisture can get into the switch.
- penetrating dust, sand and other contaminants can impair the mechanical function, in particular the smooth running of the switch.
- penetrating moisture can lead to corrosion or even short circuits on the contacts.
- the present invention therefore has for its object to provide an improved switch for manually switching electrical connections.
- a switch for manual switching of electrical contacts or electrical connections comprising an operating element which can be displaced manually by means of a movement and at least one contact element which can be displaced along a first contact path by means of the movement of the operating element, wherein the operating element and the contact element are in mutual non-contact immediate interaction, so that the contact element follows the movement of the operating element.
- the non-contact interaction makes it possible to dispense with levers, joints and other mechanical power transmission elements, whereby the mechanical wear and tear is minimized.
- the interaction is immediate, ie a movement of the operating element is transmitted directly into a movement of the contact or switching element, so that the contact element always follows the movement of the operating element. Under immediate movement is to be understood in particular that no intermediaries, such as electrical connections or lines between control and switching element are provided.
- interaction can also be two-sided, i. a movement of the switching or contact element is also transmitted in the opposite direction to the operating element. For example, when the contact element moves into a detent or depression, less force is required to do so than when the contact element is to be moved out of the detent or depression. Due to the interaction, feedback about the required actuating force can be transmitted to the operating element and thus to the user.
- Manual switching means that the operating element is actuated mechanically, for example by the hand of a user.
- the control can be handled directly by the user, with buttons and panels, as they are well known, can be provided.
- the interaction can be magnetic.
- the operating element can be magnetic in at least one section, for which purpose a permanent magnet or an electromagnet can be provided on the operating element.
- the switching or contact element can be magnetizable and have, for example, a ferromagnetic or paramagnetic section and can be made of iron, for example. This offers the advantage that the contact element can be used simultaneously for the production of electrical contact.
- the contact element can also comprise a magnetic section and the operating element can be magnetized.
- both the control element and the contact element can be magnetic.
- the magnetic interaction may be attractive or repulsive, and even switchable when using electromagnets. Due to the different magnetizations different switch functions can be realized.
- a plurality of mutually dependent or independent contact elements may be provided, whereby various switching functions may be provided with the same control element.
- the interaction in particular a magnetic interaction, can act on the contact element with a force against at least the first contact path.
- the contact element is held against the first contact path and no further spring elements, such as screws or leaf springs are required.
- the switch may also have a second or further contact paths, which may for example be arranged in parallel.
- the first contact path and the second contact path can be arranged parallel to one another.
- Further contact paths may also be arranged parallel thereto or in series with the second contact path.
- the contact element can rest on the contact paths and optionally held by magnetic force against the contact paths.
- the contact paths may have contact surfaces with which the contact element comprises an electrically conductive portion which can be brought into electrical contact by means of the first movement.
- the contact surfaces are each connected to electrical contacts, connections or connections.
- the second contact path may have a contact surface over one of its lengths, such that the contact element, when it rests on the second contact path, is in electrical contact with the contact element.
- the first contact path can have one or more contact surfaces, wherein each contact surface corresponds to a switch position and can each have an electrical connection, for example to a consumer.
- the contact surfaces can be arranged consecutively along the first contact path, wherein the person skilled in the art can adapt the arrangement according to the respective requirements.
- a movement of the contact element along the first contact path then causes the contact element is offset with respect to the contact surfaces and depending on the position of the contact element with no, one or more contact surfaces comes into electrical contact, whereby the respective contact surface on the electrical potential of the contact element is lifted and an electrical contact, or an electrical connection is made according to the switch position.
- the contact paths may comprise at least one notch, wherein the at least one notch corresponds to a switch position.
- the contact element may be located in the switch position in the at least one notch and produce a corresponding electrical contact depending on the notch. If the contact element is moved along the contact paths, where is a higher force must be applied to move the contact element from the notch, while it moves without external force via the control element in the notch into or will remain in this. As a result, a screening of the switching path can be achieved.
- the indentations can also be provided with contact surfaces, so that a contact is made only when the contact element is in the respective notch.
- the notches correspond to switch positions to which electrical switch states are assigned.
- the notches are arranged in the direction of the magnetic force, so that the contact element is pulled by the magnetic force in the notches when the operating element does not move.
- One or more indentations may be provided on the first and the second, or further, contact paths, or only on one of the contact paths.
- the person skilled in the art will adapt the number and arrangement of the notches to the respective requirements of the switch.
- the contact element and at least the first contact path can be arranged in a closed housing, wherein the operating element is arranged outside of the housing.
- the housing can be completely closed, even air and / or watertight, so that the electrical components are completely encapsulated. Since the contact element is offset by means of the non-contact interaction from outside the housing, no mechanical movements are to be transmitted from the outside into the housing for switching. Therefore, neither openings in the housing, nor movable housing sections have to be provided, which facilitates the sealing of the housing. Only electrical connections such as electrical cables must be passed through the housing wall, for which purpose suitable seals are known in the art.
- the electrical components can be effectively and permanently protected from environmental influences, in particular from dust and moisture. Depending on the housing used, this allows for continuous and safe use in dusty or damp or wet environments.
- the first contact path and / or the second contact path can be arranged on a printed circuit board.
- the contact paths can have the form of sliding contacts over which the contact element is moved.
- the contact paths may be integrated into the printed circuit board (PCB) or attached to it by known techniques.
- the switch according to the invention can also be carried out without a printed circuit board by contacting the contact elements directly by means of electrical lines or cables.
- the operating element is rotatably mounted about an axis of rotation, for example in the form of a rotary switch.
- a magnet can also be arranged on the axis of rotation or radially to the axis of rotation, so that it moves along a circular arc during a rotational movement of the operating element.
- One or more of the contact paths can also be arranged in a circular arc around the axis of rotation.
- the contact element along the circular-arc-shaped contact paths can also essentially move along a circular arc when the operating element is rotated and, if appropriate, the magnet is moved in a circular arc.
- the magnet and the contact element can be aligned along the axis of rotation and move substantially in the same radius about the axis of rotation.
- the contact element is arranged radially with respect to the axis of rotation to the operating element. If the embodiment implements a magnet, the contact element is also arranged radially with respect to the magnet and moves essentially on a circular arc around the magnet.
- the contact element can advantageously be arranged or aligned parallel to the axis of rotation of the rotary motion.
- the operating element and the contact element may be displaceable in a straight line substantially parallel to one another.
- the rectilinear movement of the operating element essentially relates to the magnet or the magnetizable section arranged on the operating element. This can be realized with the invention slider and slide switch.
- Figures 2a to 2e erfindunuxen switch in four different switching positions respectively in a perspective view and in cross section;
- Figure 3a shows an operating element and a contact element with three-sided cross-section and Figure 3b shows an operating element and a contact element with a circular cross section;
- Figure 4 shows the control element and the contact element of Figure 3b with contact paths.
- FIGS. Ia, Ib and Ic show a switch according to the invention from different perspectives.
- the switch comprises a cylindrical outer casing 2 and a cylindrical inner casing 4.
- the inner casing 4 is disposed inside the outer casing 2 on the same cylinder axis.
- the inner housing 4 may also consist only of the lateral surface of the cylinder, wherein the end faces are omitted, as shown in Figure Ic. Both housings may be made of a plastic or another, preferably insulating material.
- the switch further comprises an operating element 10 with a shaft or an axis 12, and a permanent magnet 14 is arranged.
- the first contact path 40 consists of a plurality of contact surfaces 40a, 40b, 40c, 40d, 40e, each contact surface having a notch.
- the second contact path 30 is in one piece, made of electrically conductive material or has an electrically conductive surface and comprises the same number of notches, as the first contact path 40. The notches are aligned so that a contact element 20 each in a notch in the first contact path 40 and can engage in a notch in the second contact path 30.
- the various notches and contact surfaces 40a, 40b, 40c, 40d, 40e in the first contact path 40 each correspond to a switch position.
- Various switch positions are shown in FIGS. 2a to 2e.
- the switch is shown in zero position. It corresponds to the switch position of the figures Ia and Ib.
- the contact element 20 is located in a first notch with a first contact surface 40a of the first contact path 40 and in the corresponding notch of the second contact path 30.
- a connected consumer e.g. a fan be switched off. In this case, it is not necessary to provide an electrical connection to the first contact path 40a.
- the switch is shown in a first switching position.
- the contact element is located in the second notch with contact surface 40b of the first contact path 40 and in the corresponding notch of the second contact path 30.
- This position may, for example, correspond to a first speed of a blower, wherein the contact surface 40b may be connected to the blower via a resistor.
- Other connection possibilities are known to the person skilled in the art
- Figures 2c, 2d and 2e respectively show a second, third and fourth switch position, wherein the contact element 20 in the third, fourth and fifth notch with corresponding contact surface 40c, 4Od or 40 is located. In the case of the blower, these then correspond to additional blower stages and can be connected to the blower with or in the highest level even without resistance.
- FIGS. 2 a to 2 e it can also be seen from FIGS. 2 a to 2 e that when the operating element 10 moves, its shaft 12 and magnet 14 move and the contact element 20 is displaced in accordance with this movement. There is no material connection between the contact element 20 and control element 10. Rather, the control element 10 and contact element 20 are mechanically separated from each other by the inner housing 4.
- the power transmission from the operating element 10 to the contact element 20 and vice versa takes place via magnetic interaction or via magnetic forces, as shown in Figures 3 a and 3b.
- FIGS 3a and 3b show the control element 10, consisting of the shaft 12 and the magnet 14 and the contact element 20 in more detail, with further elements of the switch according to the invention have been omitted for illustrative purposes.
- FIGS. 3a and 3b differ in the embodiment of the contact element 20, FIG. 3a showing a contact element with a three-sided cross section 20a and FIG. 3b a contact element with a circular cross section 20b. Due to the different shape, the engagement of the contact element 20, 20a or 20b in the notches can be changed and adapted to different requirements.
- the three-sided or angular shape of the contact element 20a allows a more accurate engagement in the notches of the contact paths 30, 40 whereby the positioning accuracy and the forces necessary for adjusting be increased.
- the support surface and thus the contact surface of the contact element 20a is improved with the corresponding contact path.
- the round shape of the contact element with a circular cross-section 20b enables lower forces for switching between the switching positions and moreover allows the contact element 20b to roll over the contact paths 30, 40. This is particularly advantageous if no indentations are provided on the contact paths 30, 40.
- a continuous controller such as a potentiometer can be realized.
- the contact elements 20, 20a, 20b are made of a magnetizable material, such as iron or comprise a permanent magnet.
- the contact element 20, 20a, 20b is attracted by the permanent magnet 14 of the operating element 10. As shown in Figure 4, the contact element 20, 20a, 20b thereby applied with a force against the contact paths 30, 40 and optionally pulled in de notches of the contact paths.
- the contact element experiences a force when it is moved into or out of the notches, it can also be felt by the user via the magnetic interaction back on the operating element and thus.
- the contact element 20, 20a, 20b follows the magnet on the predetermined by the contact paths 30, 40 circular arc.
- the contact element 20, 20a, 20b also pulled into the notches and it is a correspondingly higher force of the operator necessary to the Kon- continue to move tact element 20, 20a, 20b, whereby a detent feeling arises in the operator.
- the contact element 20, 20a, 20b is furthermore made of an electrically conductive material or comprises such a section. This established an electrical connection between the second contact path 30 and the respective contact surface 40a, 40b, 40c, 40d, 40e of the first contact path 40.
- the second contact surface 30 may be integrally formed of a conductive material and connected to a power supply. Then the second contact surface 30 and the contact element 20, 20a, 20b resting thereon are at the electrical potential of the voltage source.
- the contact element is located in the notch of the contact surface 40a.
- the contact surface 40a corresponds to a switch position, for example, the zero position as described with reference to Figure 2a, and may be electrically connected to a consumer or other.
- the contact surface 40a is thus turned on in the illustrated switch position, while there is no contact with the other contact surfaces 40b, 40c, 40d, 40e of the first contact path 40. The latter are thus switched off.
