Abstract

1335590 Retractive switches MOLEX Inc 31 Dec 1971 [7 Jan 1971] 60953/71 Heading H1N In a door-operated switch 32, Figs. 4, 5 mounted in a recess 16 of a door frame 4, the door 8 engages a rockable actuator 62 having a first cam portion or nose 82 which operates the movable contact 38 on initial movement of the actuator, and a second cam portion 84 substantially concentric with the pivot 69 of the actuator whereby with continued movement of the door the contact 38 is retained in its operated position. In the example shown the switch operates to close the contacts 38, 52 on closure of the door for operating a refrigerator fan, but in an alternative example, Fig. 7 (not shown), the movable contact (38a) is arranged on the opposite side of the contact (52a) whereby it is normally closed for operating a light when the door is opened and is moved to the open circuit position when the door is closed. A torsion spring 74 with a pair of radial arms 76, 78 operates to return the actuator ot its outwardly projecting position. Holes 58, 59 in the switch casing provide for the escape of water which may enter the casing in the region of the actuator 62. Resilient arms 20 integral with the casing operate to retain the switch in the aperture 16.
