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.
