ABSTRACT:
An electrical switch (1) is proposed which consists of a lower housing component (3) and an upper housing component (2). In receptacles (24) of the lower housing component (3) contact lugs (23', 23") with a normally closed contact (29', 29") are arranged. In the upper housing component (2) a contact element with a switching contact (22) is arranged. The contact element is moved, via a pressure spring (17) and a slider rod (9) to which an actuation element (5) is coupled, so as to flip between the off-position and on-position. At the contact lug (23') which is arranged on the side of the lower housing component (3) facing away from the contact element in the off-position, an arc extinction lug (32) which consists of an extension is attached to the normally closed contact (29').
