End stop for the switching shaft of a low voltage circuit breaker

摘要

The end stop system (10) for the switch shaft (12) has a bracket, typically with two bearings (14) to hold the shaft. Lugs (16) on the shaft engage with stops (18) on the bracket. Screws (20) fasten the bracket to the wall of the switch housing (22). The stops limit the rotation of the shaft without causing excessive mechanical loading.
