Reed Relay Demonstration Board

This Simple Circuit Reed Relay module features 4mm plug connections and is mounted on a base. A current through the coil activates the relay, demonstrating electromagnetic switching principles. The module is designed for constructing simple circuits of the type normally used on circuit boards. Particularly useful for younger students learning about electromagnetism and relay operation, this module illustrates how a small current can control a larger circuit. Compatible with other Simple Circuit series modules for building a variety of circuit configurations.
