- FIG. 13 comprises - as can be seen from FIG. 14 - two superimposed housing parts, namely a first housing half 83a. in which the two electrical conductors designed as contact wires 85, 86 are held in corresponding recesses, and a second housing half 83b, which rests flatly on the first housing half 83a.
- an inner labyrinth seal 90 consisting of web and groove is arranged centrally between the two contact wires 85, 86, which forms a chip protection, ie which forms a contact bridge between the two contact wires 85, 86 prevented by metal chips.
- outer labyrinth seal 91 between the outside of the first housing half 83a and an inner wall of the contact housing 84, an outer labyrinth seal 91 and between the outside of the second housing half 83b and an inner side of the contact housing 84, a further outer labyrinth seal 92 is arranged.
- Both outer labyrinth seals 91, 92 also consist of a groove and a web engaging in the groove and form a chip protection on the outside of the bridge member 83.
- the same chip guard may optionally be provided in the other embodiments shown. Otherwise, the previous statements also apply to this embodiment.
- FIGS. 15 and 16 show a further exemplary embodiment of a bridge element 103 which is arranged between the actuator 101 and the electronic circuit arrangement 102 (for example a printed circuit board).
- FIG. 16 shows a section in the plane XVI-XVI in FIG. 15. Unlike the previous exemplary embodiments, here the combination of the contact pairings between actuator 101 and bridge element 103 is on the one hand and between the printed circuit board 102 and the bridge element 103 on the other hand.
- the contact pairing with the actuator 101 according to FIG. 16 is designed as a so-called knife-and-fork contact (see also FIGS. 10 and 11).
- the terminal contact 107 is arranged, which is U-shaped as a so-called fork and a contact slot, in which a designated as "knife" contact tongue 105a, also called first electrical contact 105a, is introduced.
- the contact pressure is generated by the resilient legs of the fork 107.
- the first electrical contact 105a is electrically conductively connected by an electrical conductor embodied as a sheet metal strip 105 - through the bridge element 103 - to the second electrical contact 105b, which is designed as a spring pressure contact 105b and to one contact area (here without reference numbers) of the printed circuit board 102 is pressed. Otherwise, the previous statements also apply to this embodiment.
- Fig. 17 shows the bridge element 103 in isometric view as a single part, wherein the two first electrical contacts 105a, 106a, formed as contact tongues, and the two second electrical contacts 105b, 106b, designed as spring-pressure contacts, are clearly visible.
