Abstract
A push button switch assembly comprising a plurality of push button switch actuators includes a flexible, unstretchable electrically non-conductive belt for permitting only one of the push button switch actuators at a time to be in its activated position while the remaining switch actuators are all in their deactivated position. The switch assembly cover includes a molded detent spring for maintaining a switch actuator with a shaft having suitably axially spaced detents in its activated position when one of the detents engages the spring. The switch actuator comprises movable contacts aligned to engage respective stationary contacts disposed in the base of the switch assembly when the switch actuator is in its activated position. The belt is strung over tensioning risers disposed in a predetermined path on the base of the switch assembly at each side of a switch actuator. The switch actuator shaft further includes a groove for confining the belt therein.
