The SS3-3G60 is a pneumatic timer push button manufactured by Safety Technology International (STI), designed for access control, safety signaling, and industrial interface applications. It features a dual-mount design that allows installation either flush or surface-mounted using the included 35 mm back box and flush plate. The button’s pneumatic timer mechanism provides a timed delay for a momentary push or release function without requiring electrical power to operate, making it suitable for systems where a brief timed signal is needed. The inset button design helps reduce accidental activation, and the switch supports a wide range of operating voltages and environments.
