Abstract
A circuit breaker position switch unit is mounted to the sidewall of an industrial type draw-out circuit breaker enclosure to indicate whether or not the circuit breaker is electrically-connected within the enclosure. A time dwell is provided by the structural arrangement of the switch actuator plate with respect to the position indicator bracket. The position switch finds application where a number of circuit breakers communicate with a central processor control unit.
Claims22
A circuit breaker position indicator comprising:
- a base plate supporting a switch actuator plate;
- a microswitch intermediate said base plate and said actuator plate;
- an actuator button on said microswitch, said button positioned relative to said switch actuator plate for on-off actuation of said microswitch in response to movement of said switch actuator plate;
- a bushing arranged in abutment with a bottom of said switch actuator plate;
- and
- bias means connecting with said switch actuator plate biasing said switch actuator plate against said bushing.
