RS PRO Lever Subminiature Micro Switch, Lever Actuator, Solder Terminal, 4A, 250V AC, 28V DC, SPCO 333-316

The RS PRO 333-316 Lever Subminiature Micro Switch is a high-reliability snap-action device engineered for precise control in compact electronics, industrial, and instrumentation applications. Its lever actuator is designed to provide consistent switching operation, making it ideal for scenarios where space is constrained and precise electrical response is essential.

This switch features a solder terminal for sound, vibration-resistant electrical connections, making it suitable for equipment requiring secure mounting and long lifecycle electrical performance. The contact configuration is SPCO (Single Pole Change Over, also referred to as SPDT), offering flexible integration within control circuits.

One of the key highlights is its ultra-compact form factor, which ensures easy placement in densely packed assemblies. The device's robust design supports intensive mechanical cycles, rated at up to 10,000,000 operations, contributing to exceptional longevity and reduced maintenance in demanding environments.

The RS PRO micro switch accommodates a wide application temperature range, from -54°C up to 121°C, ensuring consistent operation in diverse climates and environments. It delivers high-precision, presence/absence detection, and its silver-plated contacts ensure reliable high-current switching and superior electrical performance.

Applications for the 333-316 model include appliances, computer/business equipment, communication devices, HVAC systems, manual and automated machinery, medical and dental equipment, office automation, test and timing instruments, vending mechanisms, door interlocks, microwave ovens, and elevators.

Users benefit from international certifications, including UL and CSA, emphasizing electrical safety and broad acceptance in regulated systems. The switch’s SPCO contact arrangement expands circuit control options, while the lever actuator supports enhanced actuation sensitivity and repeatability.

Compact design for integration into space-constrained electronic or electrical assemblies. Long mechanical life cycle suitable for continuous and frequent switching operations. Wide temperature range for robust performance in extreme conditions.

Solder termination allows for quick and reliable mounting during assembly. Compliant with international safety approvals for reliability in quality-critical installations. Engineered for both industrial and commercial equipment including HVAC, instrumentation, and security.
