2. Access the Old Switch: Depending on your tool model, you may need to remove casing screws or covers to access the existing trigger switch.
3. Note Wiring Configuration: Before disconnecting any wires, carefully observe and ideally photograph the existing wiring connections to the old switch. Note which wires connect to which terminals. The SW77 switch includes 4 internal terminals.
4. Disconnect Old Switch: Carefully disconnect all wires from the old switch.
5. Install New Switch: Position the new Superior Electric SW77 switch in the tool's housing.
6. Connect Wiring: Connect the wires to the new SW77 switch's terminals according to the configuration noted in step 3. Refer to the wiring diagram below for general guidance. Ensure all connections are secure.

Operation

The Superior Electric SW77 is a trigger-type switch designed for intuitive operation.

• On/Off Functionality: Press the trigger to activate the tool. Release the trigger to turn the tool off.
• Variable Speed (if applicable): If your power tool supports variable speed control through the switch, the SW77 may accommodate this feature. The speed typically increases as the trigger is pressed further.
• Electric Braking (if applicable): For tools equipped with electric braking, the SW77 can support this function, allowing the blade or accessory to stop quickly upon release of the trigger.
