Rotary Switches

For 1/4" Panel Cutout Dia.

Control multiple devices with one switch. Turn the shaft to change switch positions. Each position closes a set of contacts per circuit, so you can select between multiple devices on one or more circuits.

DIN-Rail Mount Motor Voltage Monitors

Mount these monitors to 35 mm DIN rail. They protect electric motors from phase loss, phase reversal, overvoltage, undervoltage, and voltage imbalance. Also known as voltage-monitoring relays, they cut power to a motor when a fault occurs.

Latching Relays

9-Terminal Relay

9-Terminal Relay Socket

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.
