Abstract

The switch has a switch pin (16,180) which locks into the depressed position. The pin acts upon the contact surface (32) of a switching foil (24) and holds it firmly against contact surfaces (28) of a circuit board (26) when in the depressed position. The circuit board and switching foil are sealed air tight with the contact surfaces between them. A distance foil (34) inserted between the circuit board and switching foil has holes (36) punched in the region of the contact surface.
