Abstract

1356961 Variable resistors; switches CTS CORP 7 May 1971 [8 May 1970] 13813/71 Heading H1S In a variable resistor for a hearing aid an actuating member 18 rotates in a housing member 11 and on it are fitted a collector 26, a spring washer 28, a stop member 29 and a wiper 30, all made of conducting material. The shoulder 22 is splayed out at 22a to hold them on the spindle and consequently to hold the spindle in the housing, flange 19 bearing on the end wall 15. The housing member sits on and is sealed by a skirt 34 round the base on which a resistance track 38 is deposited. Terminals 40 are moulded in the base member and conductive end pads 39 are bonded to the terminals. A switch may be housed in a cavity 41 in the base member. Two contacts 42, 46 are force fitted into the cavity with an insulating washer between them. When the washer is rotated by the actuating member 18 the insulating tongue 45 is forced between the contact point 42d and the lower contact 46. An insulating disc 49 seals the cavity. The housing may be of a phenolic material.
