My first post...I'm still a newbie to this stuff, but I just thought I would share a problem I recently resolved.
I have a house built in 1906. It has been upgraded in the back half of the home to 12/2 & 12/3 Romex, but the front half still has cloth insulated single wire runs with no ground wires. All of the switches in the front of the house use traveler wires with no neutral in the box. I was able to run neutral home runs (PITA) to all but one switch located in my office. The wires are just not accessible. After searching the forum, I found a resolution, installing the XPS3 in the light box and using an XPSS slave switch for local control. One problem...I didn't have/order any XPSS slave switches and I didn't want to wait for one to arrive just to finish my project. The slave switch is essentially just a momentary contact switch with an LED status indicator...
So here is my solution...
I took a standard Decora switch apart, removed the rubber bump stop from the top or "On" position and used a spring from an ordinary ball point pin, cut to length, to return the switch to the down or "Off" position, converting it to a momentary contact switch. A dab of hot glue was used to secure the spring to the rocker plate, preventing it from popping out of the bump stop recess. I wired it up as line to line and load to control on the XPS3 and presto...a poor man's slave switch!!! I may take it a step further and try to add the status LED later, but at least it works for now. I can modify another switch and post pics if anyone is interested.
