ABSTRACT:
A timing mechanism is started by pushing a plunger against a cam assembly to disengage a cam from a switch to allow the switch to close. The cam assembly is axially spring biased against a wall of the timing mechanism to stop its movement after the switch closes. The plunger is axially spring biased against the cam assembly to permit it to proceed and override the cam assembly to prevent jamming of the plunger or other elements of the timing mechanism until a stop prevents continued movement of the plunger.
