How to Replace the Switch on a DeWALT Circular Saw

The switch kit replaces an older style switch and includes wiring instructions. The switch turns the saw on and off and activates the electric motor brake. After years of use, the switch can fail, either no longer turning the motor on, working intermittently, or not activating the motor brake.

Let's get started.

REMOVING THE SWITCH   1. Remove the top half of the handle.

a. Remove the screws securing the top half of the handle assembly to the lower half.

b. Lift the top half of the handle away from the assembly.

  2. Remove the switch.

a. Remove the screw securing the switch to the lower handle.

b. Lift the switch assembly slightly out of the lower handle.

c. Note the location of the wires (for reassembly).

d. Remove the screws securing the wires to the switch and disconnect the wires from the switch.

INSTALLING THE NEW SWITCH

  3. Install the switch.

a. Connect and secure the wires to the new switch using the four screws. (If the switch in your saw is different from the new switch, follow the wiring instructions provided in the kit. If the switch in your saw is the same as the new switch, connect the wires in the same configuration.)

b. Install the switch assembly into the lower handle.

c. Secure the switch to the lower handle with the screw.

REASSEMBLING THE UNIT

  4. Reinstall the top half of the handle.

a. Tuck all exposed wiring into the lower handle.

b. Install the top half of the handle.

c. Secure the top half of the handle with the screws.
