A pneumatically actuated switching device includes an electrical connection with a conductive element and an interchangeable air connector assembly having an air conduit for receiving pressurized air from a pneumatic actuator. The pressurized air is directed into the housing of the switching device and forces a conductive plunger against the electrical connection for completing a circuit to produce a signal in a patient call system. The connector assembly has a snap fit connection constructed to selectively position the air conduit at a predetermined angle relative to the electrical connection, i.e. a first snap fit connector position the air conduit at a right angle with the electrical connection, and a second snap fit connector position the air conduit in alignment with the electrical connection. A method includes selectively inserting the first snap fit connector and the second snap fit connector into the housing depending on a desired system configuration.
