Abstract
1,094,586. Snap-action switches. PENN CONTROLS Inc. Nov. 16, 1965, No. 48592/65. Heading H2B. A switch has a spring contact arm 10 with a slot 16, the arm being transversely-bowed by a resilient U-clamp 19 having arms 17 (and 18) so as to assume a position above or below the normal plane of the arm. Upon the occurrence of a malfunction, a plunger 35 snaps the arm from the position shown in Fig. 2, to the opposite position in which contacts 24, 26 are closed (Fig. 3, not shown). The switch is reset by a button 40 which causes the part of the arm between clamp 19 and the contacts to move upwards. If the malfunction has been removed, the remainder of the arm is free to move upwards when button 40 is released, and the contacts 23, 25 reclose. If not, the contacts 23, 25 cannot be reclosed (Fig. 4, not shown).
