Outdoor Rocker Light Switches

Switch lights on and off no matter the forecast. NEMA 3R rated, these switches have a gasket that blocks out weather. They are rocker switches, so they protrude less off your wall than other switches.

Flat and completely smooth, these switches are easy to wipe down. They’re rated NEMA 3R, so they seal out water that could damage the circuitry. They also won’t corrode from mild cleaning solutions. With just a light tap, you can switch lights on and off, even if you’re wearing gloves.

302-304 Stainless Steel—Switches with a stainless steel wall plate resist wear and tear better than switches with a plastic wall plate.

Enamel-Coated Steel Housing and Powder-Coated Steel Housing—The enclosure is steel, so it withstands tougher conditions than plastic enclosures.

Fuse Holder—Use switches with a fuse holder where overload protection is needed. When the current exceeds the rating of the fuse, it blows. This interrupts the circuit and prevents overheating, damage, and fire. When used with UL Class RK1, RK5, or T fuses, they require rejection-style fuse clips. Note: Horsepower ratings are based on time-delay fuses installed.

Lockout—They have a lockout to secure in the off position using a padlock (not included).

Safety Interlock—Switches with safety interlock keep the door closed when the switch is on and prevent the switch from turning on when the door is open.

Viewing Window—Switches with a viewing window let you see the switch position without opening the enclosure.

NEMA 3R Enclosure Rating—A raintight NEMA 3R rated enclosure protects these switches from falling liquids and light splashing.

Enclosed Disconnect Switches


Power Pole	Neutral Pole

Cut power and keep it isolated to prevent equipment from starting up during inspection and maintenance. These switches are housed in a protective enclosure that resists denting, chipping, and cracking. Mount them to the wall when you run out of space in an electrical panel.

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.

Outdoor Time and Day Activated Switches

24-Hr. Timing Cycle

Designed to work with landscape lighting and filter pumps, these switches turn equipment on and off at a set time and day. They control two devices at once, and have three-prong outlets to plug devices directly into the switch. All have an override to bypass the programmed on/off settings.

24-Hr. Timing Cycle—24-hr. switches repeat the same program daily. Position trippers around the clock dial to set on and off times.

NEMA 3R Enclosure Rating—NEMA 3R rated switches are protected against falling liquids and light splashing.

Light Sensor Control—Switches with light sensor control allow one device to be controlled by the presence or absence of light.

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. More precise than other time and day switches, they program on/off times for equipment down to the exact minute. They control equipment with high currents, such as landscape lighting, pumps, and heaters. A backup battery maintains the program during a power outage.

24-Hr. Timing Cycle—24-hr. switches repeat the same program daily.

7-Day Timing Cycle—Seven-day switches can perform a different program each day of the week.

365-Day Timing Cycle—Seven-day/365-day switches can perform a different program each day of the week or year, and compensate for leap year and daylight savings time. Override regular programming for up to 99 holidays for any length of time. They can also be used to activate equipment such as bells and signals for just a few seconds.

Astronomical Timing—Switches with astronomical timing can be set to turn lights on and off based on sunrise and sunset.

Day Skipper—Switches with a day skipper can be programmed to skip operation for one to six days.
