Interlock switch baseplate assembly

Abstract From the Canadian patent

An interlock switch assembly is disclosed having a unitary baseplate with relatively few moving parts and making use of conventional low cost miniature switches each, positively located and retained with respect to the baseplate. First and second actuators convert respectively, linear motion of first and second operators into rotary motion to actuate the miniature switches. Switch actuation is prevented unless the properly timed motion of both operators is received by the actuators. A third actuator receives the motion of the first operator and actuates a third switch in response thereto. In one embodiment, the third actuator is prevented from actuating the third switch until after …
