RS PRO Surface Mounted Momentary Air Switch 1 NO/1 NC Contacts, 15 A 250 V AC, Model 316-951

RS PRO 316-951 Surface Mounted Momentary Air Switch is a highly reliable Electrical Switch designed for remote operation using compressed air, providing enhanced safety in hazardous environments such as battery charging rooms, garages, laboratories, and locations with explosive gases, vapours, or powders. This surface-mounted switch features two single-pole double-throw (SPDT) microswitch contacts, one operating before the other to allow staged switching operations with precise control.

The actuator of this air switch system consists of a bellows mechanism. When compressed, it transmits air through tubing to the switch element that expands the bellows to actuate the electric contacts, enabling total electrical isolation beneficial in wet or hazardous conditions.

Each switch contact is rated for 15 A at 250 V AC, compatible with standard industrial electrical loads. The switch is mounted securely with four No. 4 self-tapping screws, and the mounting screws must not exceed 6 mm in length to avoid damage to the bellows.

The operating pressure range is 1.2 psi with a maximum pressure capacity of 15 psi, suitable for ensuring reliable switch performance across typical pneumatic control systems. This model is compatible with 3 mm internal diameter air tubing and is UL approved, meeting recognized safety standards for electrical equipment.

The switch’s sealed system construction means temperature variations can affect pressure, so the total volume of air tubing should be kept within recommended values to maintain consistent operation. This air switch is a vital component for safe industrial, mechanical power transmission, laboratory, and fluid power applications.

Two SPDT microswitch contacts provide reliable staged switching capability. Surface mounting design for easy installation and maintenance. Bellows actuator ensures electrical isolation in hazardous environments. UL approved for safety and compliance assurance.

Designed for use with 3 mm I/D tubing in explosive atmospheres. Rated at 15 A, 250 V AC for industrial electrical applications. Operates between 1.2 psi and 15 psi air pressure. Ideal for battery charging rooms, garages, and laboratories.
