Rotary Switches
 |
For 1/4" Diameter Panel Cutouts |
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.

Surface-Mount Motor Voltage Monitors
 |
Protect electric motors from phase loss, phase reversal, overvoltage, undervoltage, and voltage imbalance. Also known as voltage-monitoring relays, these monitors cut power to a motor when a fault occurs.

Tamper-Resistant Magnetic Contact Alarm Switches
 |  |  |
Flush Mount | Surface Mount | Surface Mount with Conduit Connection |
Prevent unauthorized use of doors or windows with a combination of coded magnets and contacts that wire to an alarm system. The coded magnets mean they can’t be bypassed with regular magnets. These switches actuate when the magnet comes within sensing distance of the switch and reset when the magnet moves away. Mount the magnet to your door or window and the switch to the frame. Connect the switch contacts to an alarm system, which will trigger when the magnet is pulled away as your door or window is opened.
Flush Mount—Flush-mount switches are designed to mount against the door jam. They have a cord grip to reduce strain on your cord.
Surface Mount—Surface-mount switches mount on the surface of your door.
Conduit Trade Size 1/2—Switches with a 1/2 conduit connection are ready to directly attach to your conduit.

Solid State Surface-Mount Timer Relays
 |
Attach these relays to a flat surface using the mounting hole. They have no moving parts, so compared to mechanical switches, they require less maintenance, last longer, and are quieter.
Delayed Switch Off (Delay on Break)—Delayed switch off (delay on break) relays activate with a switch instead of input voltage. When the switch is turned off, the relay remains on for a programmed amount of time before turning off. For example, a projector’s light is turned off with a switch, but its cooling fan continues to run for a set time.
Repeat Cycle—Repeat cycle relays turn on for a duration, then off for the same duration. They alternate between the two cycles until input voltage is removed. A common example would be a flashing light.
Switch on (Single Shot)—Switch on (single shot) relays require a switch to activate the relay. They’ll stay on for a programmed amount of time. For example, lights in a storage room are turned on with a switch and stay on for a set time before turning off.
