16mm UL Certified Anti-Vibration Resistant Switch Lock

The S3012 series is Jin Tay's 16mm anti-vibration key switch lock family (S3012, S3013, S3014, S3212, S3213, S3214), rated IP65 per IEC/EN 60529 and verified by SGS third-party testing. The key provides physical authentication, ensuring that only authorized personnel can operate equipment or electrical circuits. Manufactured in Taiwan by Jin Tay since 1980.

Why Specify the S3012 Series?

• IP65 Ingress Protection: Rated per IEC/EN 60529 and SGS tested—dust-tight and protected against water jets, for washdown areas, outdoor mounting, and dusty industrial environments.

• Anti-Vibration Design: Engineered for equipment that moves or vibrates in operation.

• Durable Construction: Zinc alloy die-cast housing and cylinder with bright chrome plating; plated contacts and terminals on a fire-resistant terminal base (per product page).

• Flexible Switching: 2-position, 3-position, momentary, and multi-position configurations up to 8 positions; up to 8 terminal pins with single- or dual-circuit switching.

• OEM-Ready: Multiple switching configurations, key entry orientations, and key profile options available; wire-soldering processing on request.

Where Does the S3012 Series Fit?

Mobility scooters, golf carts, and forklifts; industrial control boxes and servers; vending machines, lawn mowers, and alarm systems—applications where power should switch only under an authorized key, and where vibration and ingress would defeat a lesser switch.
