Saia-Burgess Door Micro Switch SPST Plunger 16A 250VAC IP40 -20°C to 140°C 74106

Saia-Burgess 74106 Door Micro Switch is an industrial-grade SPST (Single Pole Single Throw) plunger type momentary switch designed to perform reliable door interlock and detection functions. Rated at 16 amps and 250 volts AC, the switch operates safely within a temperature range of -20 degrees Celsius up to 140 degrees Celsius. The device features an IP40 protection rating, safeguarding it against solid objects greater than 1mm but not against water intrusion, making it suitable for controlled indoor environments.

The switch body and plunger are made from durable glass fibre reinforced nylon and glass fibre polyamide (UL 94 V-0), ensuring mechanical robustness and flame resistance. Contact points utilize silver alloy, providing excellent conductivity and resistance to welding under harsh electrical conditions. The switching mechanism is of the slow action type with positive opening contacts that guarantee forced contact separation even in case of welding, enhancing operational safety.

This model supports easy installation with screw mounting and quick connectivity via 6.3mm Faston terminals. Its compact dimensions (height 32mm, length 30mm, width 13mm) make it versatile for integration in industrial control panels, HVAC systems, manufacturing machinery, and laboratory instrumentation requiring reliable door status detection or interlock functions.

The switch is certified to meet UL, ENEC, cUL, and CSA quality and safety standards, assuring compliance and reliability in demanding industrial and commercial applications.

Designed for industrial and electrical automation environments, the Saia-Burgess 74106 provides a robust switching solution for door interlock safety and control systems, ensuring operator and equipment protection with high contact ratings and mechanical endurance.
