    I have a solar operated pump (~24 volts as fed directly from the solar panels). I use this transmitter, together with the SECO-LARM SK-910RB2Q Two-Channel RF Receiver, to turn the water on/off when I am watering the garden, or when using the water for processing produce at my wood fired stove. I don't get more than about 150 ft from the receiver and this system works great for me. Programming and installing the receiver was very easy. I bought two of these transmitters and could use one to control a different device if needed. I programmed them both to control the same pump though. That way if I forget to bring one transmitter, the second one is kept in the shed where the pump is and I don't have to make a trip back to the house (garden is remote from home and utility power).

    Use these to activate and de-activate home security system. Have been using more than two years, no problems what so ever. Highly recommend.

    Works consistently and has the small size I was looking for. I built it into a doorbell button to control a 1-channel receiver that activates a gong hammer.
