Abstract:
A power tool having a paddle switch is configured to allow easier actuation of a switch mechanism. The power tool comprises a housing, a support surface disposed within the housing, a switch mechanism having a first position and a second position, a paddle member including an input surface and a hinge pin positioned a distance from the support surface, and a multiplier member pivotally connected to the hinge pin and having a first arm and a second arm. The first arm of the multiplier member extends from the hinge pin along a first longitudinal axis, and the second arm of the multiplier member extends from the hinge pin along a second longitudinal axis that is not parallel to the first longitudinal axis. The second arm is disposed to contact the support surface when force is applied to the input surface, causing rotation of the multiplier member about the hinge pin. The rotation of the hinge pin causes the first arm to contact the switch mechanism and move it from the first position to the second position.
