Default Turning a hose faucet into electrical on/off?

How would you guys go about turning this faucet into an electrical on/off? I've got some ideas, but it never hurts to ask.

Wouldn't that make water shoot out your outlets?

A Rotary On/off switch comes immediately to mind - something along the lines of this:

But.... Why????

Are you doing like a "secret switch" sort of thing? Does this need to have water flowing through it or just look like a faucet?

I have a coupl ideas if you're going for a "secret switch".

A momentary on switch that would be pushed down and held on by the gate inside the valve. That would fire a relay for whatever you are running.

Drill a hole in the gate and mount a long, skinny pin to it that could flick a toggle on and off.

The rotary switch is probably the easiest.

If you want it it to still flow water, I have no idea.

Quick warning in case you didn't know.

A normal switch usually incorporates some sort of spring that makes or breaks the circuit in a very quick action. This is to minimize arcing as the conductors are traveling through the area where the gap is small enough for the electricity to jump.

When I picture a gate valve, I think of the plunger moving really slow as the handle is turned. If that were relied on to close the circuit, it would allow the electricity to arc for quite awhile as the contacts were slowly brought together. It would also allow the user to stop the plunger just short of making a solid connection, letting heat build as the electricity tries to move accross.

I would try to find a commercially made switch that could be activated by the valve somehow. A momentary switch (button type) wired directly would not be a good idea for the reasons listed above.

Depending on the load, I would try and find a really small toggle switch that could be worked by a push/pull rod rigged to the turning of the valve.

Do you have any lathe experience? If not, you could find someone to make it, but if you do you can make it yourself. Use a push on / push off button type of switch. You can get "micro-switches. I'll snap a pic of one type in a second. You would need to take the packing out of the valve, and make a new piece that foes in that the handle would screw to, but underneath the packing nut, you'd have to have a small spring and a micro switch. Push down on the handle to turn it on and push down again to turn it off. If you can't find a switch small enough, you could make another housing that looks like the valve only a little larger. The bad part, you need to isolate the wires and connections from ever touching the copper and brass.

Another thing you could look at doing is go to Big Lots, Odd Lots or whatever it's called and pick up a cheap touch lamp, rip the guts out of it and use it in your setup. That way, all you would have to do is touch the lamp anywhere to turn it on or off.

Well....I can't find mine. I think the wife scarfed on that stuff. Anyways, here is a pic of a couple different types. The small round one could possibly work.

Ok, it has nothing to do with water. . .that's cool. I like the lamp idea.

I would just get a rotary switch, gut the valve and get creative with some JB weld. Just so you can turn the knob on and off.

Seems to be the easiest approach.

I think that would be sweet as well.

Check this out:

Or just pick up some old touch lamps from the thrift store and gut the wiring.

How about mounting a micro reed switch inside under the plunger inside the faucet? This may not meet your needs, but there are many sizes and specs to chose from. http://www.pic-gmbh.com/files/pmc0701_ds_e_3.3.pdf

Agree with whomever said the rotary / clicker switch like you see on a common lamp. I think using a push button switch could be dangerous as you may over crank the valve and crush the switch. Flip side, you may not seat the switch button fully and cause the contacts to arc. Either could lead to a short and thus fire or shock.

Using a rotary switch would also be super simple to integrate into the valve body.

Just get a 1/2 '' or 3/4'' normally closed electric solenoid valve for the water line. Pipe it in water line, add power and a switch.
