Claims

[Claims for Utility Model Registration] (1) In a circuit or disconnector that includes a microswitch as an accessory device and an operating pin that engages with the actuator of the microswitch, the operating pin is biased in the trip direction. A circuit or disconnector comprising a biasing member, the biasing member increasing the stroke of the operating pin during tripping. (2) A microswitch is attached to the mechanism frame via an insulating plate, and an arm that engages with the operating pin is provided on this insulating plate, and the elastic force of this arm is used to bias the operating pin in the trip direction. 1. A circuit breaker or breaker according to claim 1 of the utility model registration claim, characterized in that: (3) Utility model registration claim 1, characterized in that the lever on which the operating pin is provided is provided with a tension spring, and the operating pin is biased in the trip direction using the pulling force of the tension spring. Circuit breakers and breakers as described in section.
