Abstract

520,459. Retractive switches. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 31, 1938, No. 31453. Convention date, Oct. 30, 1937. [Class 38 (v)] A switch suitable for operation by the door of a refrigerator comprises an insulating operating member 20 having trunnions 21 engaged in recesses in an insulating housing 11 provided with a central slot in which the member 20 can move. Normally a door holds member 20 in the position shown. Oh opening the door, a spring 14 moves member 20 to cause a cross pin contact 23 to bridge a pair of contacts 27 mounted in grooves in the housing to light a lamp. The switch parts are held in position by a cover 39 having an insulated lining 42, the cover having lugs 40 which are sprung into recesses in the casing. Attachment of leads to the contacts 27 is effected by passing the bared end of the conductor through a hole in the upper end of the contact and then punching the side of the contact to crush the conductor in the hole. This forms a recess into which the lead is bent before inserting in the switch housing.
