Choosing an Electrical Switch
More
Light-Sensing Light Controls
Automatically turn outdoor lights on and off based on lighting conditions to conserve energy. A time delay prevents false switches due to brief exposure to a light source, so a car driving by or a lightning flash at night won’t signal your light to turn off.
Conduit-hub-mount controls are often used with electrical enclosures, junction boxes, and light fixtures. They fit a 1/2 conduit trade size, so you can mount them anywhere a compatible knockout is available. A rubber O-ring seals out moisture. Those with a pivot or swivel head let you adjust the position of the sensor to align the photocell with a light source and sensing area.
On at sunset, off at sunrise controls turn on at sunset and off when the ambient light is above a certain level.

Air-Actuated Relays

Also known as an air-to-electric switch, this relay converts an air signal to an electric signal. Use it to actuate solenoid valves and other electric components from your pneumatic control system.

Wireless Enclosed Relays

Send a signal to turn equipment on and off from up to 150 feet away without having to run electrical wire. These relays have an enclosure to protect the terminals from dust and accidental bumps. They can be set to transmit, receive, or both at once. You’ll need at least two relays to switch a device. They have an alarm that can be set to check for certain conditions before transmitting a signal. For example, you could set these relays to send a signal to turn on an air conditioner if all windows are closed. The repeat function extends the transmitting signal through a maximum of two receiving relays.
Relays that are set to transmit can be linked up to as many receiving relays as you need. Relays set to receive can be linked up to 30 transmitting relays. All relays connect to dry contacts on your switch, sensor, or controller. Use the wire leads to connect them to a power source.
UL and C-UL listed, all meet American and Canadian safety standards. Rated NEMA 1, they should only be used indoors.
