Wireless Pendant Switches
Operate equipment from up to 330 feet away—these switches include a transmitter and a receiver that connects to equipment. Use up to 45 wireless switches in the same area. They're rated IP65 for protection from washdowns.
Two-speed switches have staged contacts. For slow speed, press the button halfway down to close the first contact. For high speed, push it all the way to close the second contact.
Switches and replacement transmitters that cannot be sold to Canada are restricted by product labeling requirements.
Replace worn stickers or change the function of a button with labels. Packs include commonly used functions such as up, down, start, and stop.
To Order: For existing systems, please advise which channels are currently in use so that a different channel can be provided. For the replacement transmitter, please specify the serial number.

Magnetically Actuated Switches
These switches actuate when a magnet comes within sensing distance, and reset when the magnet moves away. They’re often used to detect when a door or window opens. Mount the switch in a stationary position, such as a door frame, and mount the magnet to a movable object, such as the door. They do not include a safety relay and cannot be used with safety-guard doors found on machinery.
NEMA 4X rated switches are protected from corrosion and washdowns. These switches are also rated IP67 for protection from temporary submersion.

Magnetic Contact Alarm Switches
Wire contacts to an alarm system to alert when doors or windows are opened. Mount the magnet to the door or window and mount the switch to the frame. The alarm will activate when the magnet is pulled away by the opening door or window.
SPDT switches connect to an alarm system and to another device, such as a motion detector.
