Honeywell Technologies Roller Lever Micro Switch, Solder Terminal, 1A, 125 V ac, SPDT

Honeywell Series SM Micro Switch, 125V AC Contact AC Voltage, 1A Switch Contact Current - 311SM68-T

This micro switch is a Compact electromechanical device designed to provide reliable single-pole changeover switching in control and sensing roles. It is intended for use where a low-force, rapid-response actuation is required and is suitable for installation in equipment operating across a broad temperature span.

Features and Benefits:

• Subminiature construction delivers space-saving installation benefits
  Roller lever actuator enables smooth mechanical interfacing with moving parts
  SPDT contact arrangement permits changeover control of a single circuit
  1A switching current supports low-power signal and control circuits
  Solder Terminal offers straightforward PCB or wiring assembly
  Mechanical endurance rated for 10,000,000 cycles minimises replacement frequency

Applications

• Suitable for limit switching on automated conveyors and actuators
  Ideal for position detection in Compact electromechanical assemblies
  Used for control inputs in instrumentation and testing rigs
  Can be used for tactile sensing in consumer appliance mechanisms

What environmental temperatures can it withstand in continuous use?

It operates across a wide thermal range from -54°C up to 121°C, allowing deployment in both cold-storage and elevated-temperature equipment.

How does the actuator type affect interfacing with moving parts?

The roller lever reduces contact friction and permits reliable engagement with sliding or rotating elements while lowering actuation force requirements.

What material contributes to electrical insulation and thermal tolerance?

The housing is MADE from a phenolic compound that provides electrical insulation and maintains structural stability at higher operating temperatures.

Which approvals and regulatory markings are associated with this component?

It carries recognised approvals including CSA, UL, RoHS, ENEC and CE for broader acceptance in industrial and commercial applications.

What operating force is required to actuate the switching mechanism?

The device requires an actuation force of approximately 0.39 N, enabling sensitive and precise triggering in control systems.
