PNEUMATIC SWITCH FOR PATIENT CALL SYSTEM HAVING MULTIPLE-POSITION HOUSING ASSEMBLY

摘要

A pneumatically actuated switching device (10) is disclosed for forming a momentary electrical signal circuit with a receptacle of a patient call system utilizing a conductive plunger (38) which slides in response to a pulse of pressurized air delivered to an internal chamber (31) through a housing connection (16, 24) which provides for optional assembly orientations. A spring (40) is used to maintain separation between a conductive plunger and the electrical components when the pneumatic switching device is not achieved by a patient.
