Abstract

Improvements in or relating to electromagnetic switches adapted for overload tripping according to which a circuit breaker arrangement comprises two contacts, one of which we will call the second contact is normally latched in contact with the other which we will call the first contact, making means to unlatch said second contact when fault conditions or current defects occur and which allow the said first contact to be disconnected as well as means to voluntarily press the repeated first contact out of engagement with said second contact while this second contact is latched.
