switch test

[jhnidy]

If I install an x10 wall switch into one wire on an extension cord, can I test the switch?  My latest eBay deal may not be as good as I thought it was.

Thanks

Is it a two wire dimmer type or a relay type with a line load and neutral connection?
You should be able to test the switch with a power cord and a lamp load.
Exactly how you connect it depends on if it is a two wire dimmer type or a three wire relay type.

Piggybacking on Brians response - yes.

But you should use a polarized extension, and cut the "hot" line (the line to the narrow prong on the plug). Connect the switch black wire to the line going to the plug, and connect the blue wire to the line going to the socket.

It is a two wire.  I will wreck a cord rather than pull one of my already installed units out of the wall.


If I hang an ohm meter on the leads, it shows open even if I push the button.  I wish I had a known good one so I could ohm it.

No the two wire wall switches need a 40 or more watt load to work.
They steal their power through the load. An Ohm reading is not a good indicator of a X10 switches condition.

Line ---------- X10 Switch ---------- Load Line connection.
Neutral ------------------------------Load Neutral connection.

I saw one enterprising user. Take an extension cord and cut the line lead in the middle to splice in the switch. Then used a table lamp in the cords outlet side and  plug in the cord to the AC wall to test.

Before you go too far. Double check the small safety disconnect slide switch is not in the off position.
The one used for safely disconnecting the switch when you change the bulb.
You are using the switches with a incandescent type bulb?
