RS PRO Air Switch Actuator This actuator from RS PRO converts air pressure into a mechanical force. It controls the movement of an air switch, which in turn opens and closes contacts on an electrical circuit. This device is particularly useful in hazardous or wet environments as it allows for the remote operation of an electrical circuit. The unit's large volume bellows makes it compatible with a wide range of air pressure systems and increases its versatility. A durable thermoplastic body withstands even the harshest of conditions without any negative effects. This material also makes the switch completely resistant to rust. Use this air switch in laboratories, garages, or wherever explosive gases, vapours or powders may be present. Its remote operation increases workplace safety by isolating personnel from electrical equipment that operates in volatile environments. Engineers have tested this part for quality, safety and reliability. It also meets Restriction of Hazardous Substances (RoHS) standards, which means it contains only minimal amounts of any harmful materials. Features and Benefits - Suitable for tubing with internal diameter of 3 mm - White button and escutcheon - Operating temperature range of +10°C to +40°C
