Abstract
An insulating casing is formed with one open end and a longitudinal slot through one wall. A plug member is detachably fixed to the casing by means of interlocking projections and arms to close the open end of the casing. The plug member is formed with a shield plate which coextensively extends through the interior of the casing. A slider member is formed with a slot through which the shield plate slidably extends and an actuating handle extending through the longitudinal slot in the casing. A resistance plate is disposed between the slider and a wall of the casing opposite to the wall through which the longitudinal slot is formed. The resistance plate is formed with a resistance element with which a slider contact fixed to the slider member slidingly engages.
Claims8
A variable resistor assembly comprising:
- an elongated casing having one open end and a longitudinal slot formed through one wall thereof;
- a plug member detachably fixed to the casing to close the open end thereof, the plug member having a shield plate extending therefrom coextensive with the interior of the casing;
- a slider member formed with a slot through which the shield plate of the plug member slidingly extends, a handle extending from a first side of the slider member through the longitudinal slot of the casing and a slider contact extending from a second side of the slider member which is opposite to the first side thereof;
- and
- a resistance member disposed between the second side of the slider member and the casing and being formed with a resistance element with which the slider contact slidingly engages.
