Click here to learn more about our Tinytrol line of miniature air switches.

Presair Tinytrol Miniature Air Switches are single function controls that provide safe on/off actuation of electrical devices from remote locations such as motors, lights, pumps, or other applications. Air switches are designed to use an air bellow actuator joined by tubing to an air switch contained within the equipment. Pushing the actuator creates enough pressure to operate the air switch which safely controls the equipment. There is complete electrical isolation with no voltage to worry about at the point of actuation.

Competitors such as Tecmark, Herga, and Lefoo offer distinct series of miniature air switches, engineered for specific applications. This article focuses on Tecmark’s TBS series, Herga’s 6871 and 6872 series, as well as Lefoo’s LF40-01 series. If you currently utilize one of these series and are exploring alternatives or seeking a precise cross-reference, this guide is tailored to you. Whether you’re an experienced technical professional or navigating the technical details of miniature air switches, our cross-reference guide is designed to streamline your decision-making process, ensuring a precise match for your specific technical requirements.
