Abstract
A trigger-lock control for a motor switch of a power tool is presented including a trigger attached to a rigidly connected elongated slide portion which reciprocates in a housing containing switch components arranged longitudinally in a 'power-on' and 'power-off' arrangement so that the slide portion can selectively operate these contacts when it is reciprocated by motion of the trigger. A spring urges the trigger and slide portion normally to a power-off position and locking means is provided to lock the elongated slide portion in the power-off position by providing an oscillating lever having a downwardly extending point at its free end which enters into an upwardly opening recess in the upper wall of the slide portion when the parts are in the power-off position. The lever is pivoted on a horizontal pivot on the top of the housing and joined to the lever is either a thumb piece or a lever adapted to be easily operated by a hand of the operator holding the tool.
