Abstract
An electrical switch having conductive contact elements each pivoted about a stationary middle contact block is disclosed. The contact elements are each formed as a triangular spring open at one apex and having a bearing the side thereof opposite the open apex for engaging its respective middle contact block. The other two sides of each spring, depending on the switch position, rest under spring tension against one or the other of stationary contact blocks arranged on either side of its respective middle contact block. The ends of these two sides adjacent the open apex are formed with hooks which are positioned with a minimum of friction in recesses and oblong openings in a rotatable actuating element, under spring tension, in such a way that the contact element serves to produce a snap action as the actuating element is rotated.
