This is a VSR (Variable Speed Reverse) switch used in various power tool models, including hammer drills and power screwdrivers. The VSR switch serves to power the tool on and off, as well as control the motor speed and direction. Over time, the VSR switch may malfunction, resulting in your tool not turning on or changing speeds as intended. If you observe difficulties with your power tool, it is likely that the switch needs replacement. Please note that this switch is sold individually and does not include any additional hardware, such as screws or wires. Replacing the switch is a straightforward process that only requires a screwdriver or drill. Start by disconnecting your tool from its power source, whether it is a power cord or battery, and then remove the screws on the side of your tool to access the inner housing. Disconnect the wires attached to the old switch, followed by removing the switch itself. Install the new switch and connect its motor wires first, and then the power supply wires. Once all the wires are securely attached, reassemble the housing and fasten it with the necessary hardware.
