Abstract

503,504. Snap - action switches. POOLEY, C. A. Oct. 6, 1937, No. 27120. [Class 38 (v)] A snap-action switch has a switch blade member 6 carrying a contact 7 supported in cantilever fashion, and a separate and detachable blade spring 14 held in compression between a groove 15 in a support 12 and a lip 13 at one end of the member 6. The member 6, the support 12 and an operating lever 9 are mounted by means of a screw 10 on a base 8 which also carries two fixed contacts ! 16 and 17, and contact members 11, 18 and 19, which are held in a main base 1 by screws 20 and 21. A casing 2 and cover 3 enclose the switch, which is actuated by a knob 23 pressing on the lever 9 through a rubber sealing diaphragm 26. Pressure is transmitted through a pin 22 to the spring blade member 6 which moves with a snap action in the manner described in Specification 419,917, [Group XXXVII]. A screw adjustment of the support 12 and a stop screw 25 to limit the movement of the blade 6 may be provided. Modifications are described of the U-shaped support 12 and of the substantially triangular or rectangular compression blade 14 with suitable co-operating members 6.
