High-Current Time and Day Activated Switches

Control equipment with high currents such as landscape lighting, pumps, and heaters. Program these switches to turn a device on and off at a set time and day. Position trippers around the clock dial to set on and off times.
24-hour switches repeat the same program daily.
Seven-day switches can perform a different program each day of the week.
Switches with a day skipper can be programmed to skip operation for one to six days.
Additional trippers (sold separately) are sold in pairs that include one “on” tripper and one “off” tripper.

Outdoor High-Current Time and Day Activated Switches

Rated NEMA 3R, these rain-tight switches protect against falling liquids and light splashing. They control equipment with high currents, such as landscape lighting, pumps, and heaters. Program them to turn a device on and off at a set time and day. Position trippers around the clock dial to set on and off times.
24-hour switches repeat the same program daily.
Seven-day switches can perform a different program each day of the week.

Washdown Enclosed Disconnect Switches
Rated IP66, these switches are protected from washdowns. They cut power and keep it isolated to prevent equipment from starting up during inspection and maintenance.
Switches with lockout secure in the off position with a padlock with a maximum shackle diameter of 5/16” (not included).
Use additional power poles to control more than three circuits. Add neutral poles to open and close the neutral leg of a three phase system.

Infrequent-Cycle High-Current Relays




For use with equipment that cycles on and off, these relays meet UL 508 for air conditioning and heating. Connections are accessible from the front, so you can mount relays side-by-side. Also known as definite-purpose contactors.
Enclosures (sold separately) are NEMA 1 rated to protect contacts from corrosion.
Also Available: Auxiliary contacts for 3.8"-7.2" Ht. relays. They allow you to add a signaling device or control another relay. Please select 6564K99, then select the McMaster-Carr part number of your relay and whether you want to switch one circuit on (1 Normally Open) or off (1 Normally Closed).

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 35 mm DIN rail. They have an integrated heat sink that disperses heat to provide optimal convection cooling. An LED indicator tells you if they are open or closed. Relays are rated for continuous operating duty. They do not switch DC loads.
