Honeywell Technologies Roller Lever Micro Switch, Solder Terminal, 5A, 250 V ac, SPDT

Honeywell Series SM Micro Switch, 250V AC Contact AC Voltage, 5A Switch Contact Current - 111SM2-T

This micro switch is a Compact electromechanical switch designed for precise actuation in control and sensing systems. It operates as a single-pole double-throw device with a roller lever actuator, providing deterministic changeover behaviour for on/off or signalling tasks in industrial and electronic environments. The unit is built for a wide thermal range and routine switching in demanding cycles.

Features and Benefits:

• 5A contact current supports moderate load switching applications
  250V AC rating suits common mains-related control circuits
  SPDT contact layout enables changeover logic without relays
  1.95N operating force provides consistent, repeatable actuation
  10,000,000 mechanical operations permits long service intervals
  Phenolic housing resists electrical tracking and offers insulating integrity

Applications

• Suitable for limit sensing in automation machinery with lever actuation
  Ideal for control panels requiring Compact changeover switching
  Used for position detection in electromechanical assemblies
  Can be used for safety interlocks in auxiliary circuits
  Used with custom brackets where a solder-terminal connection is preferred

What terminals are provided for electrical connection?

The switch uses solder-type terminals that allow direct wire or lug soldering for Compact assemblies.

How does the actuator form affect installation options?

The roller lever actuator converts linear contact into rotational motion, enabling actuation by cams, sliding parts or contacting edges with reduced wear.

What environmental temperatures can it withstand during storage and operation?

It is rated to function down to −54°C and up to 121°C, covering low-temperature and elevated-temperature operating conditions.

What approvals ensure suitability for regulated applications?

It carries approvals from recognised standards bodies including UL, CSA and CE for use in compliant equipment.
