The 134 Pressure Electric Switches are used wherever it is necessary to close (or open) an electrical circuit on the basis of a predetermined air pressure signal. This switches to be used in areas protected from the weather. Typical applications include the control of air compressors, fans,pilot lights, resistance heating elements, control of electric heating loads or motors on fans, pumps or small air compressors.
