Problems solved by technology

[0007] A disadvantage of the known key switch caps is that in order to avoid wear in the event of repeated actuation of the pressing area of ​​the switch cap, a correspondingly resistant material should be selected
However, this has the result that the region of the switch cap in which the snap-in or latching process takes place during the switching process has to be designed cost-intensively.

Embodiment Construction

[0022] figure 1 The key switch cap according to the invention is shown in a sectional view. The key switch cap 1 is composed of a central pressing area 2 , a deformation area 3 and a sealing area 4 . The sealing area 4 can also be referred to as the edge area of ​​the key switch cap 1 . The central pressing area 2 and the edge area 4 are here made of a harder material than the deformation area 3 . In this case, the central pressing area 2 and the edge area 4 can be made either of the same material, for example plastic, or of different materials, as long as the two materials are each harder than the material from which the deformation area 3 is made.

[0023] exist figure 1 Among them, the key switch cap 1 according to the present invention is rotationally symmetrical. Of course, the key switch cap 1 according to the invention can have any desired shape, as long as the deformation region 3 surrounds the central pressing region 2 and the deformation region 3 is surrounded by...

Abstract

The invention relates to a key switch cap (1) made of flexible material for a key switch (5), wherein the key switch cap (1) comprises a central pressing area (2), surrounds the central pressing area (2) and A deformation area (3) connected thereto and a sealing area (4) connected to the deformation area (3), wherein the central pressing area (2) and the sealing area (4) are made of a first plastic material, and the deformation area is made of a second Made of two plastic materials, wherein the first plastic material is harder than the second plastic material.

Description

technical field [0001] The invention relates to a pushbutton cap for an electromechanical component, which can be used, for example, in a locking system of a vehicle. Background technique [0002] If a switching function is required in the electromechanical component, then the switch is selected and integrated into the electromechanical component as a separate component. Usually these switches have a key switch cap for operating the switch. In this case, the key switch cap serves in particular to transmit force to the switch contacts. [0003] Electrical contact switches of this type are used as miniature switches, microswitches or subminiature switches in many fields of application (eg automotive technology and domestic appliance technology). In such a switch, the sliding contact is introduced from one contact position to the other with a sliding movement. In this case, an electrically conductive connection should only take place at the corresponding contact points. [...
