Switch module for a power tool

A power tool comprising:

• a housing;
• a motor disposed in the housing;
• and
• an electronic module disposed partially within the housing, the electronic module configured to provide a signal indicative of a target speed of the motor, the electronic module comprising:
• a circuit board comprising a plurality of conductive pads coupled to a power source and a sense pad coupled to an output signal;
• and
• a variable-speed actuator assembly including an actuator positioned adjacent a side edge of the circuit board and moveable along a movement axis perpendicular to the side edge, a link member coupled to the actuator and moveable with the actuator along the movement axis, and a wiper made of conductive material secured to the link member in contact with the circuit board, the wiper having a first leg arranged to slidably engage the sense pad and a second leg arranged to slidably engage at least one of the plurality of conductive pads when the actuator is pressed;
• wherein the sense pad is longitudinally aligned with the plurality of conductive pads along an axis that is parallel to the movement axis of the actuator, and wherein the first leg of the wiper is located between the actuator and the second leg, and the sense pad is located between the side edge of the circuit board and the plurality of conductive pads.
