tINYTROL AIR SWITCHES
The Presair air switch system uses an air bellows actuator connected by tubing to an air switch mounted inside the equipment or appliance. Pressing the actuator generates air pressure that travels through the tubing to actuate the switch. This configuration provides complete electrical isolation at the point of actuation, with no voltage present. No external compressed air source is required.
The Tinytrol® Miniature Air Switch is available in both single-pole and double-pole configurations, with options for momentary or alternate action switching.
