Is there a difference between an AC or DC switch ?

Yes, Max current allowed is typically much lower for dc compared to ac for a given switch.

I only used the pressure switch with CA to control water pumps. I don't know if it could be used with DC.

I suspect you can use either AC or DC. However if DC is being used then it's polar sensitive. Perhaps it's on the idea of a universal motor which will run on both AC and DC but if DC is connected backwards the motor will run backwards.

Our circuits are 120 volts or there about; sorry, don't know if it has a switch for anything else. Contact Sangean directly for a definitive answer.

No it is not. It replaces a regular toggle switch for lights or fan, A GFCI is usually only for outlets.

AC. If the light is powered by a switch using house power it should always be AC unless you've installed DC converters throughout your house.

I did not see such a switch, although I was not looking for one either. There is a switch that controls fan operation. Do you mean for 60hz or 50hz? In either case, the power cord is configured for 110v.

It can work with AC or DC - 12 volts. I'm using it to switch 12V DC lights.

I bough for use on automotive service only which use DC ...so ..on AC I have no tried

Just wanted you to know that the wiring on this thing is backward, at least as far as the DC part is concerned. I don't use the AC part. In other words, it only works when you hook your DC input (battery) to the output side, and your output to the side marked "battery." The printed instructions that came with this item is wrong. If you hook it up according to the manual, it will not work.

What difference does it make, as long as you can adjust the two screws to produce the correct DC current up to 12 volts. This item was not designed to produce a light show in blue.

Our unit puts out 120 Volt and 240 volt AC current. It does not put out DC at all!

Both are ac/dc, but mine are always plugged in , less static interferance. I used the batteries before and didn't like it because it was too static. The batteries wore out in a few days.

Correct. The relay is actually turned OFF ONLY at the zero cross point of the AC wave. It can be turned ON at any point in the wave depending on your needs, load, EMI requirements etc. So with DC it would turn on but not off (no matter what your control input) unless the DC voltage dropped to zero for whatever reason. Also It would likely NOT handle anything like the rated voltages(give as RMS) with DC load.

AC or DC makes no difference as long as the amp rating and voltage rating are not exceeded. Ohm's Law doesn't care which it is in this application.

"DC" current (direct current) is the type of current that comes from a car battery. "AC" (alternating current) is the type of current that is supplied to your home, and that is needed to power larger electronics. That's why you need a Power inverter that allows you to convert DC current to AC current, if want to use larger electronic devices in your car. Since the manufacturer states that the tool, "Automatically detects and indicates low voltage (12-48V AC) and standard voltage (48-1000V AC)", it apparently will not detect "DC" current.

As I understand it the controlling coil is rated for 12vdc. The switch itself is rated for up to 250vac 10a. So while it will control a ac/dc light the relay coil can only take 12vdc. 12vac will probably not be able to pick up the relay.
