Abstract
463,906. Snap-action switches. BOLLINGHAUS, W. April 30, 1936, No. 12347. [Class 38 (v)] The switch mechanism of a snap-action switch including an actuating member 3, which may be actuated directly or by two push-buttons and a contact arm 1 is mounted on the bridge 7. The member 3 has fixed to it an intermediate member 4 which engages a pin 12 pressed upwards by a spring 11 in a recess of the arm 1, moving the spring over dead centres and causing the arm 1 to be moved into its other position. Positive actuation is effected by teeth 19 on the dolly engaging the sides of a V-shaped groove in the top of the contact arm 1, and layers of rubber 8 on the bridge damp the impact of the contact arm. In a two-pole switch, Figs. 4 and 5 (not shown), contact strips are arranged on both sides of the contact arm and are connected at the top to studs which act as pivots, and in a three-pole switch, Figs. 8 and 9 (not shown), a contact strip is fixed on each of three sides of a long block forming the movable contact member. In another modification, Figs. 6 and 7 (not shown), rubber shock-absorbing pads are arranged on the insulating members that support the bridge.
