ABSTRACT:
An interlock assembly is for locking the operating assembly of a safety switch when the cover thereof is open or removed. The safety switch includes an enclosure with the cover and side walls. The operating assembly includes a bracket and a spring-toggle mechanism with a spring-biased drive link having an arm. An operating handle, which is coupled to the spring-biased drive link, operates the operating assembly. The interlock assembly includes a pivotal lever having a catch and a sensing portion. A pivot receives a blind rivet and pivotally couples the pivotal lever to the side wall. A torsion spring biases the pivotal lever toward engaging the arm of the spring-biased drive link in order that the catch engages and locks the arm when the cover of the enclosure is open. The sensing portion is engaged and pivoted by the cover when it is closed.
