Hand-operated double-acting trigger switch

摘要

A hand-operated, double-action trigger switch is mounted in the handle area of a portable electric tool and comprises a thumb-actuated safety button protruding from the upper portion of the handle and a finger depressable trigger on the lower portion of the handle. The safety button must be pushed by the operator's thumb before the trigger can be depressed. Upon release of the pressure on the trigger, the safety button returns to its original position and effectively places the device in an inoperable or locked position.
