  • 20 Amp rating supports demanding power-tool motors
  • Trigger on-off action gives instant motor control

Switch Overview

The Superior Electric SW77-20 is a 20 Amp trigger on-off switch designed for pneumatic and hydraulic power tools. It functions as a direct replacement component for specific Skil worm drive saws and Ryobi or Ridgid models. The switch manages on/off operation, variable speed control, and electric braking by momentarily reversing electrical polarity. Mechanical wear eventually requires replacement to restore tool function.

Who It Suits

This switch suits owners of compatible Skil worm drive saws using part number 2610321608 or Ryobi and Ridgid tools using part number 760245002. It is intended for users comfortable disassembling power tools to replace internal electrical components. Buyers needing a switch for other tool brands, higher amperage ratings, or different mounting configurations should look at alternative parts. Those unwilling to perform internal repairs should seek professional service.

Installation Notes

Installation involves opening the tool housing, disconnecting the worn switch, and wiring the new unit to the existing leads. Basic soldering or crimping tools and a multimeter for verification are typically required. Common issues include misidentifying the correct part number, damaging wire insulation during removal, or incorrect wiring causing loss of variable speed or braking function. Always verify the tool is unplugged before starting work.
