Does anyone know where I could acquire a remote controled on/off switch the size of a dime that could be used to open and close the circuit between a 3 volt CR2032 battery and an LED bulb? See the photo below for a visual on what I am looking for. The remote control would only need to have two buttons (on and off) and a very short range.
Thanks
Bombledmonk,
Thank you for your reply. The purpose of the device is to enable the user to turn on LED bulbs located inside small paper lanterns. By using a remote switch you can turn on many of the lamps at once.
An alternative solution would be a very small "pinch" on/off switch that could be sandwiched between two sheets of the material used to make the lamps. This would require turning on each of the lamps individualy. Not as elagant a solution, but workable.
The lanters are actually made from 5 mil clear polyester so the electronic components need to be as unobtrusive as possible. See the photo below. The battery and bulb assembly is contained in an envelope slipped in to the center of the lantern. The lantern size is 7" tall by 3" deep by 4" wide.
You might be better off just going with some of those keychain led flashlights with the switch built in. I can see it being a big hassle to make this reliable and run wires down to the edge if you are going to be building these by hand. For what you are asking a reasonably priced wireless solution is probably out of the question, but other ideas may exist.
I'm thinking something like this.
