Abstract
An electrical switch with connector interlock apparatus having a reusable clip-on anti-vibration retaining clip assembly used to retain the spring biased operating member in the 'on' position for high vibration application. In heavy high vibration environments, the clip assembly prevents the pushrod/operating member from vibrating out and tripping the circuit breaker. The clip assembly includes a clip preferably formed from 16 gauge pre-galvanized steel. One end of the clip is generally U-shaped to Fit into a groove formed in a bushing mounted in the wall. The opposite end of the clip extends over and engages the knob of the operating member thereby acting as the stop for the pushrod knob. With a plug inserted into the module, the pushrod must be pushed in to a second position in order to actuate the circuit breaker thereby compressing a pushrod spring. This results in stored energy in the spring. When vibration is introduced with an amplitude in the axial direction of the pushrod, the pushrod may work it way out with assistance from the compressed spring. The clip assembly prevents the pushrod from vibrating out under these conditions.
