ABSTRACT:
An electrical switch with a magnetic core for driving a first contact for engaging a second spring mounted contact. A plunger can engage the core to move it into a winding moving the first contact so that current is supplied to the winding for holding the core in inner position when the first and second contacts connect. The plunger carries an arm which can engage the spring mount for the second contact and move it away from the first contact, only when the second contact is in its deflected position by virtue of engagement by the first contact. A housing, an indicator light and connecting terminals are also provided.
