Touch and Contact Switch Kit

Both types of switch are built onto the one PCB so you can see and explore how each type works. A battery can power the touch switch (2 contacts) but a main power supply (like DIY Kit 4) must be used for the touch plate (1 terminal) to work. High quality 12V relay rated at switching 240V/3A supplied. Uses 14011 IC.
