Abstract
529,097. Retractive switches; retarding action of switches. C.A.V., Ltd., (formerly C.A.V.- BOSCH, Ltd.), and BEDGGOOD, V. May 12, 1939, No. 14194. [Class 38 (v) ] . A short-time switch, suitable for motorvehicle direction indicators, comprises a cam g rotatable by a handle-actuated spindle e to bring either of a pair of spring arms h carrying contacts i away from a stop o and into engagement with a fixed contact c, in which position the arm h is latched behind the shoulder m of one of a pair of pivoted catches k loaded by a common spring r which normally holds both catches against a stop p. A spring mechanism (not shown); wound by the handle-movement, returns the cam g and handle to the initial position at a pre-determined rate, the cam engaging a projection n and freeing the arm h near the end of its stroke. A friction clutch may be associated with the spring mechanism to allow a slight overrun of the handle. Spring- loaded, pivoted arms may replace the spring arms. The Provisional Specification refers also to a single movable and fixed contact.
