Abstract

Eine elektrische Schalteinrichtung hat auf einer Leiterplatte (1) eine elastische Schaltmatte (4) mit einem hutartigen, von der Leiterplatte (1) abgehobenen Schaltbereich (5), der an seiner inneren Stirnfläche (7) eine elektrisch leitende, bei Druck auf den Schaltbereich (5) gegen Leiterbahnen (2, 3) der Leiterplatte (1) bewegliche Schaltbrücke (8) hat. Diese Schaltbrücke (8) ist durch ein von der inneren Stirnfläche (7) gehaltenes Metallplättchen gebildet.

Figure 00000001
An electrical switching device has an elastic switching mat (4) on a printed circuit board (1) with a hat-like switching area (5), which is lifted off the printed circuit board (1) and has an electrically conductive switching surface (7) on its inner end face (7). 5) against switching tracks (2, 3) of the circuit board (1) movable switching bridge (8). This switching bridge (8) is formed by a metal plate held by the inner end face (7).
