Abstract
A mechanical switch-door interlock assembly includes a mounting assembly and an actuator assembly. The actuator assembly includes a body, a door sensor, an operating mechanism handle actuator, and a number of sliding coupling components. The actuator assembly body is slidably coupled to the mounting assembly. The actuator assembly body moves between a first position, wherein the operating mechanism handle actuator does not operatively engage the operating mechanism handle, and a second position, wherein the operating mechanism handle actuator operatively engages the operating mechanism handle and moves the operating mechanism handle to the second position. When a door is in a first position, the door operatively engages the door sensor and moves the actuator assembly body to the first position. When the door is in the second position, the door does not operatively engage the door sensor allowing the actuator assembly body to move into the second position.
