Contact element

摘要

A contact element which, on account of its low installation depth, is suitable for use in switch panels of low overall height and can be combined with various keys. The contact element has a main body, two connection terminals, which are obliquely mounted in the main body, for electrical conductors, two busbars which are in each case electrically connected to one of the connection terminals and run from the respective connection terminal to a bearing arranged centrally in the main body. A tappet which is spring-mounted in the central bearing can be moved between a first and a second position and is fitted with a contact bridge which electrically short-circuits the two busbars in one of the two positions, wherein a portion of the tappet, which portion projects out of the main body, is designed to be coupled to a key.

主权项

1. A contact element, comprising:
a main body; a first terminal and a second terminal, suitable for electrical conductors, which terminals are obliquely mounted in the main body; a first busbar and a second busbar, each electrically connected to one of the terminals and extending from the respective terminal to a central bearing arranged centrally in the main body; and a plunger, which is spring-mounted in the central bearing, the plunger being moveable between a first and a second position and the plunger supporting a contact bridge, which electrically short-circuits the first and second busbars in one of the two positions, wherein a part of the plunger protruding from the main body is configured to couple to a button, wherein the plunger includes a central hole and a side hole, provided beside the central hole, wherein the central hole is configured to receive and mount a contact spring, which contact spring exerts a spring pressure on the contact bridge, wherein the side hole is configured to receive and mount a return spring, which return spring presses the plunger into the first or second contact position, wherein the contact bridge is mounted in the central hole, wherein the plunger includes an elongate opening in each of two opposite sides, through each of which contact ends of the contact bridge protrude, and wherein the plunger includes on an underside thereof, on each of the two opposite sides, an assembly opening for installing the contact bridge.
