ABRA Electronics :: Educational Kits :: Alarms/Sirens/Sounds :: CW Touch Paddle/Touch Switch

CW Touch Paddle/Touch Switch

This versatile kit features TWO independent
touch circuits. An economical alternative
to expensive CW paddle devi-
ces. 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 6-12 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.
