Default Remote electrical control

Surely there has to be a simple product out there somewhere that I can't find that one of you has seen.

I have a customer with a boat lift installed in his dock. It uses a 1hp motor attached to a pipe to winch the boat out of the water. The electrical is simple enough with a toggle switch UP-OFF-DOWN . He wants to be able to lift the bunks back out of the water once he is in his boat and away from the dock, and lower them back down when he returns. He will not be in the boat as it's actually lifting/lowering. He's not that brave and smart enough to know better.

What I'd like to do is just replace his wall mounted switch with a remote control that can be carried in the boat or on a keychain, and I don't want to hack apart the electrical on a garage door opener. Anybody know of something simple?

option, I have a couple of the 2 circuit and they work well. If you need to make the range longer just add a longer piece of wire to the antenna.

They make similar for turning on and off a mojo decoy. You can find them at bass pro. You would have to use a relay to handle the current.

I guess I shoulda mentioned, it's not a 12v system. He's got full household current all through his little dock.

Originally I thought one of the ceiling fan controllers could be rigged to work, but there's no way to reverse the polarity. They work by setting the fan to full speed at the unit itself, then the electronics just select the amount of voltage to send the motor.

The range shouldn't be too big of a deal, no worse than pulling up in a driveway. Maybe I should look at a couple of my parts garage door openers and see how they work, might be simpler to just hack one

All you need for 12 volts is one of the wall wart power supplies to run the board and use the 110 through the relay if you get to that point.

Radio Shack used to have something like that, was for remote switching.

I see what you're saying now Scotts... shouldn't be too hard.

How would you wire that up using one of their boards? I havn't seen the motor yet, so all I can assume is it's a 3 wire setup and the switch controls the polarity.

The board in the link has 4 relays, you would use 2 of them, 1 up and 1 down.

Click on the links in the instructions and it shows how it works. They actually are using it to turn off and on a 110 volt light. The instructions explain it somewhat. There is a picture of the board and fob on the instruction sheet.

The thing I like most about this one is the remotes are $10 The garage door ones are 2 to 3 times that much. If you go this route go ahead and get spare remotes. They may not have them when you need them next time.

The boards I linked to have 4 relays, they are currently showing out on the 2 relay boards. 2 would do what you want to do.
