Abstract
An improved pneumatic actuator for an electrical switch having a flexible diaphragm operating through a rigid disk member actuates an electrical contact when air pressure is applied to the diaphragm. A cylindrical ring acts as a guide for the rigid disk member. The rigid disk member serves to flatten the membrane and resist permanent deformation when air pressure is released from the membrane.
