Abstract

997,403. Electromagnetic relays-control members for switches. AMERICAN MACHINE & FOUNDRY CO. Dec. 18, 1961 [Dec. 28, 1960], No. 45354/61. Heading H2B. A flat spring contact member 21 is secured to a terminal pin 24 so that its free end can move normal to the axis of the pin 24 and is provided with a stiffening ridge 30 between the pin 24 and a bend in the spring so that the free end of the spring moves about a centre located substantially at the bend. The spring is the movable contact of a relay as described in Specification 997,404 and co-operates with two fixed contact springs 19, 20. The free ends of the fixed springs 19, 20 are slotted at 31, 34 to provide divided contact fingers 32, 33 and 35, 36 of different widths and natural frequencies. The ends of the contact fingers 32, 33, 35, 36 are bent so as to be parallel with the adjacent faces of the spring 21 and the different effective lengths of the contact springs results in wiping contact after engagement. The springs 19, 20, 21 are secured to pins 22, 23, 24 by soldering and edges 27, 28 trap the solder which prevents longitudinal and rotational movement of the spring on the pin.
