Abstract

917,466. Retractive switches. BAUMER, H. Nov. 28, 1960 [Dec. 11, 1959; Oct. 13, 1960], No. 40792/60. Class 38 (5). In a snap-action retractive switch comprising a push-button 13 acting on a lever 8 pivoted at 10 to one of three contact connectors 3, and a U-shaped contact arm 6 pivoted in notches 11 formed in the depending ears 9 of lever 8, a wiping action between the contacts occurs even when the pivoted end of contact arm 6 is in line with the axis of a dead-centre tensionspring 7 which is connected to the arm 6 and the connector 3. The wiping action occurs because the force exerted by the ears 9 on the contact arm 6 makes an acute angle with the axis of the spring in the dead-centre position (Fig. 4, not shown). The lever 8 may be replaced by a member which moves rectilinearly at an acute angle to the spring axis. The dimensions of lugs 6a of arm 6, the provision of ears 3a, and the distance s, Fig. 2, are such that the arm and lever cannot be displaced by impact.
