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.
