Sequenced Latching Relays

These relays switch through a series of different circuit configurations every time they receive an input voltage. The input voltage latches them in position, so they don’t require a constant voltage to stay switched. Use them to control motors, pumps, and lighting. The covered terminals prevent contact with live connections. Mount to 35 mm DIN rail. Also known as step relays.

Latching Relays


A single, momentary input voltage switches these relays and latches them in position, so they don't require a constant input voltage to stay switched. A second momentary voltage will release the latch.
Relay sockets (sold separately) mount to 35 mm DIN rail.
