Abstract
620.452. Tumbler switches. CRABTREE & CO., Ltd., J. A., and MORGAN, R. W. Jan. 17, 1947, Nos. 1671 and 9270. [Class 38(v)] In a snap-action tumbler switch, wherein a relatively small separating gap between the contacts is maintained during the major portion of the movement and is then followed by an enlargement thereof, the U-shaped contact t is tiltable about a projection p on the base, and is connected, by means of a spring n and a pin m, with the dolly g. Initial movement of the dolly causes the flat bottom of the contact t to seat on the platform r', in which position it remains until the dolly moves overcentre, whereupon the contact t tilts into engagement with the other fixed contact d. The contact t is preferably bent from a flat strip, and the pin m may engage an inverted cup o surrounding the spring or a plunger inside the spring, Fig. 4, (not shown). In a modification, Figs. 5, 6, (not shown), the contact t contains an insulating liner. Specification 565,960 is referred to.
