Abstract
A push button actuated excess current protection switch, particularly an on-board electrical system protection switch with manual actuation and bimetal controlled automatic tripping includes a switch latch (7) actuated by the push button (41) and a bimetal tripping device for releasing the switch latch (7) with the bimetal tripping device including a self-heated approximately U-shaped punched bimetal (101) which is connected electrically in series in the current path through the switch. The one free arm end (102) of the bimetal is fastened to the end of a connecting lug (5) fixed in the interior of the switch housing. Its second free arm end (104) is fastened to a connecting piece (106, 106') leading to a mating contact (9') that is fixed to the housing. The base (114) is formed by the deflectable end of the bimetal which is kinematically connected with the switch latch. Between the connecting flap (105) of the connecting piece (106, 106') for the second arm end (104) of the bimetal (101) and the region of the connecting piece (106, 106') adjacent the mating contact that is fixed to the housing, the connecting piece is provided with a constriction (111) formed by a slit passing through the plate-shaped central section of the connecting piece (106, 106') transversely to the plane of the plate. The connecting flap (105) is rotatable, in order to adjust the response value of the bimetal (101), around the constriction in that an adjusting screw (110) charges the central section from the bottom face of the switch housing.
