TW200700198A - Trigger switch for power tool - Google Patents

Abstract

The invention is a trigger switch for power tool comprising a trigger, an electric conduction slice which is fixed in the trigger. Bended on the electric conduction slice, a first electric slice, a second electric slice, and a third electric slice are extended toward the moving direction of the trigger. The electric conduction slice is electrically connected to the first electric slice, the second electric slice, and the third electric slice in one piece. A control circuit contains a first electrical circuit and a second electrical circuit which are connected in parallel connection. The first electrical circuit is used for controlling the first electrical load of the power tool. The second electrical circuit is used for controlling the operation of the motor of the power tool. A first connecting slice, a second connecting slice, and a third connecting slice are set corresponding to the first electric slice, the second electric slice, and the third electric slice in the control circuit. The first electric slice, the second electric slice and corresponding first connecting slice, and the second connecting slice are formed into a first switch which controls the first electric circuit. The first electric slice, the second electric slice and the third electric slice and corresponding first connecting slice, and the second connecting and third connecting slice are formed into a second switch which controls the second electric circuit.
