About the 24Vdc Latching Relay

 Latching relays (sometimes called the Keep, Stay, Fail-safe or Impulse relays) are often used to 'make' a circuit without the need to keep the coil energised. This has the ability to switch a circuit on and off or, most commonly, to switch power from one circuit to another.

 Switching is achieved by using a single electrical pulse across the coil terminals 30 (24V +) and S (to switch or ground -) to energise the internal coil, and is triggered by the use of a momentary On-Off switch, which reduces the time duration the switch is kept closed. The pulse pulls the coil in to switch the circuit from 56 (+feed) and 56b (+feed), to 56 (+feed) and 56a (+feed or not connected for off). Once the momentary on switch is pressed again, the coil is energised again, and the circuit switches back to 56 and 56b.

 The latch relay is often used in energy-saving applications because of its minimal power drain on the batteries.
