The 20/40/60 (SD16008) and the Auxiliary Control Switch (SD16009) were designed to be installed as dry contact switches and this article provides the instructions for installing these two switches in this manner. To install these switches in a 120 VAC configuration, please see 20/40/60 Timer and Auxiliary Control Switch 120 VAC Wiring Options. If you are not sure about any part of these instructions, consult an electrician.

Note: All Swidget Devices require a neutral wire. If you don't have a neutral wire, please see the I don't have a neutral wire article.

DRY CONTACT INSTALLATION:

1. Turn OFF power at circuit breaker or fuse.
2. Note: Before installation, determine which wires are the load and line. To do so, cap each of the wires, turn the power back ON at the breaker, and check which of the wires is energized using a voltage detector. Turn the power OFF at the circuit breaker before moving on.
3. Install the Swidget 20/40/60 or Auxiliary Control Switch according to the diagram below. Use the wire nuts provided. The wire nuts can accept three 14 AWG wires.
4. Insert the new switch into the wall box and install your faceplate (sold separately).
