RS PRO Panel Mounted Latching Air Switch 687 Series 1 NO/1 NC 319-758

RS PRO 319-758 Panel Mounted Latching Air Switch from the 687 Series provides a secure and reliable solution for remote air-operated switching in hazardous areas. This switch is specially designed for environments such as battery charging rooms, laboratories, garages, and locations where explosive gases, vapours, or powders may exist, ensuring total electrical isolation for enhanced safety.

Featuring a double-pole, momentary or latching mechanism, the switch utilizes two SPDT microswitches that act simultaneously to deliver robust switching performance. The contacts support 1 NO/1 NC configuration and are rated for up to 15A at 250 Vac or 30Vdc, offering versatility for varied industrial applications. Connection is facilitated via standard 250 terminals (1/4 inch), enabling straightforward integration into electrical systems.

Installation is flexible, with the option to mount through panels using the supplied 9/16 UNF nut or surface mount via additional 3.2 mm fixing holes compatible with M3 screws or No. 6 self-tapping screws. The system is actuated by a bellows that compresses air via tubing to the switch element, providing total electrical isolation and minimizing arcing risks. This makes it an ideal solution for wet or hazardous settings where safety is paramount.

The switch operates efficiently in temperature extremes ranging from -10°C to +60°C, subject to air tube length limitations. Its sealed system prevents external environmental impact, supporting reliability even in challenging industrial conditions.

Certified to both UL and CSA standards, the RS PRO 319-758 switch meets international safety requirements. Its compatibility with 3 mm I/D air tubing further broadens application possibilities across laboratory, manufacturing, and commercial facilities.

This product finds significant utility in industrial and laboratory scenarios, including battery charging stations, hazardous material storage, and any setting requiring safe, remote switching. Explore more RS PRO safety and actuator solutions in the EnvMart Switches & Sockets category.
