Honeywell Series SM Micro Switch, 250V AC Contact AC Voltage, 5A Switch Contact Current - 11SM1-T


This micro switch is a Compact electromechanical snap-action device designed for precise switching in control and sensing systems. It provides a reliable changeover contact arrangement and is suitable for integration where a small form factor and consistent actuation are required. Manufactured with a rigid thermoset housing, it operates across a wide temperature range and connects via solder terminals for PCB mounting.

Features and Benefits:


• SPDT contact arrangement supports both make and break circuits
• Rated for 250V AC allowing use on mains-voltage control lines
• 5A contact current capacity suits medium-power switching tasks
• Operating force of 1.39N ensures predictable actuation sensitivity
• Mechanical endurance of 10000000 operations reduces maintenance frequency
• Temperature tolerance from -54°C to 121°C permits deployment in extreme environments

Applications


• Suitable for limit switching in industrial automation equipment
• Ideal for user-interface switches on electrical control panels
• Used with sensor arrays for position detection in machinery
• Can be used for PCB-mounted safety interlocks and feedback circuits
• Suitable for retrofitting into electromechanical assemblies requiring Compact switching

What material is used for the enclosure and why is it suitable?


The housing is MADE from phenolic, a heat-resistant thermoset that maintains structural integrity at elevated temperatures and provides electrical insulation for dense assemblies.

How is the switch terminated for circuit connection?


Connections are provided via solder-type terminals designed for through-hole PCB soldering and reliable electrical contact in assembly processes.

What operating environments can it withstand in terms of temperature extremes?


The device functions across a broad range from -54°C up to 121°C, enabling use in both sub-zero and high-temperature industrial locations.

How long can it be expected to function under repeated actuation?


The switching mechanism is rated to complete 10000000 mechanical operations, indicating suitability for high-cycle applications.

What approvals cover its use in regulated installations?


It carries recognised conformity marks including CE, ENEC, UL, RoHS, and CSA, supporting acceptance in multiple regulatory contexts.
