Saia-Burgess Short Lever Subminiature Micro Switch, SPDT, Solder Terminal, 5A, 250V AC, IP67, Model V4NST7Y1UL

The Saia-Burgess V4NST7Y1UL is a short lever, subminiature micro switch designed for high reliability with a 5A, 250V AC rated SPDT (Single Pole Double Throw) contact configuration. Its solder terminal design simplifies PCB mounting and connections. The robust housing is constructed from fibreglass reinforced nylon, providing UL94-V0 flame retardance and durability in demanding industrial and electrical environments.

With an IP67 ingress protection rating, this micro switch is sealed against dust and water, making it suitable for usage in harsh or outdoor industrial settings. The operating temperature range spans from -40°C to +85°C, allowing the switch to function reliably across extreme conditions.

The microswitch requires an operating force of only 0.9N, delivering sensitive mechanical response with a long mechanical life rated at 5 million operations, ensuring a durable service life. Dimensions are compact, with the solder version measuring 10mm in height, 6.5mm in width, and 20mm in depth, supporting integration into tight spaces.

This switch is compliant with industry safety and performance standards UL, ENEC, and CSA, suitable for automation systems, control panels, and electrical safety applications. The V4NS series is well-known for its reliability and established usage in manufacturing and industrial automation sectors.

The design and specifications make it appropriate for both commercial and industrial electrical switching, limit switching, and detection control roles. Its combination of IP67 sealing and compact form factor supports use in machinery, HVAC systems, and process control environments where environmental protection and robust switch performance are critical.

The housing material is fibreglass reinforced nylon for flame retardance and durability. The IP67 rating ensures protection against dust ingress and water immersion. SPDT contact configuration provides versatile switching capabilities.

Operating force is low at 0.9N allowing easy actuation. The switch endures up to 5 million mechanical operations for longevity. Operating temperature range covers -40°C to 85°C for extreme conditions. Solder terminals enable secure and easy PCB connections.

Compact dimensions facilitate installations in space-constrained areas. Certified under UL, CSA, and ENEC standards for assured quality.
