Abstract
848,089. Retractive switches. ROBERTSHAW-FULTON CONTROLS CO. April 23, 1957 [April 23, 1956], No. 12950/57. Class 38 (5). A snap-action switch operable as a limit switch, has bowed springs 34 between a contact carrier 26 and an actuating blade 30 fixed on a plunger 32 slidable in an aperture 40 in the housing and on a pin 54 having its head 56 in a further aperture 58. A spring 60 compressed between the head 56 and the blade 30 urges the plunger upwards. Projections 52, 66 on the blade 30 and carrier 26 engage in holes 70, 72 in the springs 34 so that the springs roll on the edges 80, 82 of the blade and carrier. Silver contacts 28 on the carrier 26 can bridge fixed pairs of contacts 36 or 38 which are retained in slots 74, 76 in the housing with their ends projecting to form terminals. When the plunger 32 is pressed the contacts 28 continue to bridge the contacts 38 until the blade 30 is in the same plane as the carrier 26 when the carrier is snapped over so that the contacts 36 are bridged. When the plunger is released it is returned by the spring 60 so as to snap back to the original position.
