30 mm Emergency Stop Panel-Mount Push-Button Switches
Immediately cut power with a single push. These switches are rated for protection from low-pressure streams of water and oil/coolant spraying. They have positive force contacts that will open a circuit when actuated even if a spring fails or the contacts stick. Switches include enough contact blocks to control the number of circuits listed.
Turn twist switches back on by twisting the button and pull switches by pulling it. Add an optional lockout on either kind to cover the button and prevent changes its position.
Note: Illuminated switches include a bulb. If wiring the switch and the bulb to the same circuit, the circuit voltage must not exceed bulb voltage.
Additional contact blocks (sold separately) can be added to control more circuits, or to replace the included contact block.

Easy-Clean Touch Light 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.
Switches with a stainless steel wall plate resist wear and tear better than switches with a plastic wall plate.

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-hour switches repeat the same program daily.
Seven-day switches can perform a different program each day of the week.
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.
Switches with astronomical timing can be set to turn lights on and off based on sunrise and sunset.
Switches with a day skipper can be programmed to skip operation for one to six days.

Raintight Enclosed Motor Switches

Start and stop motors outdoors and in other wet environments. Rated NEMA 3R, these switches seal out rain and light splashes. They’re housed in a protective aluminum enclosure, so you don’t need to mount them inside an electrical panel. The enclosure is lighter in weight than stainless steel enclosures yet still stands up to water and oil.
In addition to turning motors on and off, these switches work with other circuits, such as lighting and electric heat circuits. They do not provide overload protection.

Outdoor Durable Disconnect Switches

A raintight NEMA 3R rated enclosure protects these switches from falling liquids and light splashing. The enclosure is steel, so it withstands tougher conditions than plastic enclosures. All have quick-make/quick-break action to eliminate arcing and prolong switch life. They have a lockout to secure in the off position using a padlock (not included).
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.
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.
Switches with a viewing window let you see the switch position without opening the enclosure.

Enclosed Disconnect Switches
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.
Switches with lockout secure in the off position with a padlock with a maximum shackle diameter of 5/16” (not included).
Photovoltaic switches can be used with photovoltaic cells which convert sunlight into electricity.

Manual Transfer Switches

If there’s a power outage, flip the toggle for each circuit on these switches to backup power. Each circuit can also be turned off completely. To prevent injury and damage to your generators, they are open transition, meaning the contacts disconnect from one power source before connecting to another. This is also known as break-before-make switching.
Use them with a portable generator.
NEMA 3R switches can be used outdoors since they seal out rain, snow, and sleet.
Switches with a key lock prevent unauthorized changes to the switch.

Airflow-Actuated HVAC Switches

Use this switch to sense changes in airflow velocity in duct. The paddle extends into the duct and actuates the switch when airflow reaches the setpoint. Switch is rated NEMA 3R for protection from dirt, falling liquids, and light splashing.
