The PresAir Trol TinyTrol SPDT latching air switch is built for compatible systems that depend on a single-pole latching response from a pneumatic input. A correctly matched switch is important because the entire control pattern can change if the wrong switching action is installed.This replacement is especially helpful when the original air switch no longer changes and holds state the way the control system expects. Installing the proper TinyTrol latching model can help restore cleaner, more predictable operation.It is a useful part when the service objective is to maintain original system logic and restore reliable pneumatic actuation.
