About Relays

High-Current Toggle Switches

Able to withstand high currents, these switches are often used with motors and pumps.

High-Current Rocker Switches

Able to withstand high currents, these switches are often used with motors and pumps.

High-Starting-Current Rocker Switches

Also known as high-inrush current switches, these switches can handle starting currents up to 10 times greater than their rating, such as when a motor starts.

Submersible High-Starting-Current Rocker Switches

Rated IP67 for protection from dust and temporary submersion.

High-Amp Outlet-Box-Mount Key Switches

Timer Switches

High-Current Time and Day Activated Switches

Control equipment with high currents, such as landscape lighting, pumps, and heaters.

Outdoor High-Current Time and Day Activated Switches

Rated NEMA 3R, these rain-tight switches protect against falling liquids and light splashing.

Outdoor Set-to-the-Minute High-Current
Time and Day Activated Switches

Rated NEMA 3R, these rain-tight switches protect against falling liquids and light splashing.

Set-to-the-Minute High-Current
Time and Day Activated Switches

For precise control of high-current equipment such as landscape lighting, pumps, and heaters, these switches schedule on/off times to the exact minute.

High-Current Wall-Mount Timer Switches

Control equipment with high currents such as air conditioners, heaters, and ventilation fans.

High-Current Relays

DIN-Rail Mount Long-Life High-Current Relays

With no moving parts, these solid state relays have an extended service life. Mount them directly to DIN rail.

High-Current Relays

Use these relays with large motors and lighting systems.

Infrequent-Cycle High-Current Relays

For use with equipment that cycles on and off, these relays meet UL 508 for air conditioning and heating. Also known as definite-purpose contactors.

DIN-Rail Mount Infrequent-Cycle High-Current Relays

Mount these relays directly to DIN rail.

Replacement Contacts for High-Current Relays

Replace worn contacts instead of replacing the entire relay.
