A really easy to build and use kit.
N.B. The actual relay supplied may vary slightly from the image above due to voltage and manufacturer, the actual relay specification is detailed fully below..
Requires 3v to power the relay coil (between 2.8v to 4v will do).
The control input (IN) requires just a few milliamps at anywhere between 2.5v and 12v, this can be supplied by a simple switch, a TTL level signal, a microcontroller or even perhaps a computer (you need a suitable output).
- Low cost way to control larger voltages and currents
- Supplied as a kit
- Easy to build
- On-board switching transistor.
- On-board back EMF protection.

Dimensions: 50mm x 26mm x 19mm
Pinouts (from the left)
GND (often termed minus on a battery)
IN control line (your control signal)
PWR power supply (coil requires ~400mw)
A1 - contact 1 (normally open switched contact)
