Description

Presair TRM117A Tinytrol Air Switch activates electrical contact when pressure is sensed from an air actuator or other device. These compact switches support straightforward on/off control based the press and release of the air actuator. Tinytrol air switches deliver complete electrical isolation with zero voltage at the point of actuation making them a reliable control solution in hazardous environments.

Presair’s TR TinyTrol Air Switch uses a system where the air bellows actuator are joined by tubing to an air switch contained within the equipment or appliance to be switched. Pushing the actuator creates enough pressure to operate the air switch which safely controls the equipment. Typical distance between Presair actuators and Tinytrol air switch for alternate action is 20 feet, for momentary action distances of tubing up to 35 feet.  Distances of 100 feet are available, please consult factory for more information. No external compressed air is required.

Their small size and variety of connection styles allow for easy integration into a wide range of systems.

TRM117A Tinytrol Air Switch is designed and manufactured to exacting standards to meet the needs of original equipment manufacturers and instrument makers for a low cost, stable switch, and good repeat accuracy.

Presair switches deliver complete electrical isolation with zero voltage at the actuator to shock the user or spark an explosion. Presair is a leading manufacturer of pneumatic controls. The switching system costs are comparable or lower than digital controls meeting the needs of original equipment manufacturers.  We offer a wide variety of options to meet original equipment manufacturers product requirements.
