ABSTRACT:
The invention relates to a quick make and break switch, particularly to measures which permit the positive opening of the normally closed contacts if the contacts in question are welded, and then to utilize the measures taken to make possible the opening of contacts even in the case where the elastic element necessary for rapid opening is fractured.
According to the invention, this is achieved in that the rocking lever has a second arm whose second end arranged opposite the first end is located in the vicinity of the movable contact and is supported beneath the inverter member in the form of a rigid bracket if the latter has not switched under the action of the elastic blade at the time when alignment is performed and in that the lever pivot is located substantially equidistantly from the push-button of the second end.
