This kit comprises two boards. One has both a Touch Plate (with a single contact plate) and a Contact Switch (that uses two contact plates). The second board carries the switching circuitry and a latching relay output (Relay Datasheet).
Simply touch the appropriate pad to turn lights and other mains appliances ON/OFF. Useful for disabled people. The switching PCB can be positioned away from the contact plate PCB for remote control applications.
Simply touch the appropriate pad to turn lights and other devices ON/OFF. Ideal for disabled people. The switching PCB can be positioned away from the contact plate PCB for remote control applications.
The Contact Switch only needs a battery to power it but the Touch Plate requires a power supply like kit 3004 or 660.446UK. Ideal for education (demonstrates IC's in flip/flop switching applications).
For a momentary delay action touch activated switch please see our 3137 board.Specifications
