Step 6: Mounting the Switch, Finishing Up
Now, push the excess extension cord back through the hole in the junction box, leaving a few inches of play to install the top plate with. Thread the clamp nut on the clamp threads, and tighten by finger and then with a pair of pliers, until the clamp will not rotate against the junction box. Line up the two pieces of extension cord that go through the clamp, and tighten the clamp down just enough to hold the cords where they will not slip.
Slide the top plate onto the screws in the junction box, and snug down the screws. You're done!
Be sure to test the footswitch with a multimeter or by plugging a light into the extension cord's outlet and pushing the switch. The light should turn on and off as you push the switch.
