The parts that make it work.

The GRI CB-20HD is an open loop, momentary call button from George Risk Industries, built as a durable panic switch for 12V DC systems. It does one simple job: close an SPST contact when pressed so a connected alarm or call circuit can respond. Its compact 1.14″ x 2.25″ size suits installers and businesses who need a small, low-resistance call point.
