Touch once - it�s on, touch again - it�s off, or use the momentary outputs that stay on only as long as touched. Touch contact may be a door knob, small coin, or even a well watered plant! Uses low power CMOS circuitry and functions on the principle of hum and noise pick-up when input is touched. Will drive loads up to 100 mA such as relay, bell, siren, etc, runs on 6 to 12 VDC, kit includes info on using as a key for CW keyers. And, we saved the best for last - there are two completely independent touch switch units on each kit PC board, it�s like getting 2 for 1 (and no, you can�t buy just half of this kit!).
