ABSTRACT:
Switch arrangement with switches completely equipped both for normally closed and for normally open operation, in which, by means of an insulating part which can be selectively placed operatively with respect to the contact pieces which cooperate as breaker or the contact pieces which cooperate as maker, one type of operation in each case is blocked. For this the insulating part has abutment stops, which in both inserted positions in each case lie outside the contact places and which assure an air spacing between the contact pieces which thereby are blocked from making contact.
