Abstract
483,840. Tumbler switches. TUCKER, J. B. Nov. 6, 1936, No. 30225. [Class 38 (v)] A tumbler switch of the kind described in Specification 455,800, comprises a dolly b which operates a contact arm c through a link a and against the action of a mouse-trap spring biassing the contact arm towards the closed position. In the open position, the toggle a, b is slightly overset. This construction. provides a quick make and a slow break suitable for use with alternating current. To render the action silent, the movement in either direction is terminated by the engagement of the link a or a tail piece a<1> with the underside of the domed part of the dolly, and not by a moving part engaging one of the fixed parts of the switch. This effect is augmented by the provision of a rubber buffer d on the link a and a rubber washer e on the dolly.
