1. A pressure operated electrical switching device, comprising:
- a housing having two sharp edges formed on a top portion thereof on opposite sides of a longitudinal axis of the housing;
an axially movable switch plunger disposed in said housing along the longitudinal axis;

Abstract
An electrical switching device includes a switch plunger which is axially displaceable within a housing and two opposing radially directed rocking levers each disposed on a sharp edge formed on the housing. When pressure is applied to the switch plunger, the rocking levers are caused to rotate about the sharp edges and thus each actuate an associated microswitch. The transformation ratio between the stroke of the switch plunger and the stroke of the switch pen of each microswitch can be adjusted by movement of the microswitch with respect to the associated rocking lever.
