Abstract
An electronic switch and control module for a power tool having an electric motor is provided. The module includes a module housing including a bottom surface, side walls, and an open face, a printed circuit board (PCB) received from the open face of the module housing and securely disposed within the module housing at a distance from the bottom surface of the module housing; power switches mounted on a top surface of the PCB, and heat sinks discretely arranged and each mounted over a respective one of the plurality of power switches and secured to the top surface of the PCB to transfer heat away from the power switch through the open face of the module housing. The module further includes an input unit having conductive tracks disposed on the PCB and an electro-mechanical element engaging the plurality of conductive tracks, the input unit generating a signal for controlling a switching operation of the plurality of power switches, and a controller mounted on the PCB configured to control the switching operation of the power switches based on the signal from the input unit.
