  • Trigger switch and electric tool provided therewith
    Patent number: 8550181
    Abstract: An electric tool has a rib projecting from an inner peripheral surface of the electric tool, and a trigger switch. The trigger switch has a housing having a housing venthole, a contact mechanism disposed in the housing, and a trigger that, when depressed into the housing, drives the contact mechanism. The housing of the trigger switch is bonded to the rib. The rib has a rib venthole. The housing venthole is communicated with the rib venthole. The rib venthole is covered with a filter.
    Type: Grant

  • Trigger switch
    Patent number: 7557321
    Abstract: A trigger switch has a chassis, a slide member slidably retained in the chassis, a trigger connected to the slide member and projected from the chassis, the trigger configured to slide the slide member when the trigger is drawn towards the chassis, a pair of power-supply connecting terminals connected to a power supply, a pair of motor output terminals connected to a motor, a speed control circuit configured to output a current to the motor output terminal while controlling the current when the speed control circuit is connected to the power supply, a first contact mechanism configured to connect the power-supply connecting terminal to the speed control circuit when the trigger is drawn by a first amount; and a second contact mechanism configured to connect the power-supply connecting terminal to the motor output terminal when the trigger is drawn by a second amount.
