<<<<<< MORE kits .....  view other available kits >>>>>>

This kit toggles a miniature relay when you touch the sensor plate with your finger.

The circuit works in the touch ON / touch OFF  (or bi-stable) mode. 

The transistors Q3 & Q4 form a transistor-transistor T-flip-flop which toggles its state when the plate is touched
The kit is ideal for use a teaching aid to explain how transistor-transistor T-flip-flop works.
