Honeywell Series SX Micro Switch, 5A Switch Contact Current, 250V Contact AC Voltage - 311SX4-T

This micro switch is a subminiature mechanical switch designed for precise actuation in Compact control systems. Fitted with a roller lever actuator, it detects mechanical movement and delivers a single-pole changeover contact action suited to control, sensing and interlock roles within electrical and automation assemblies.

Features and Benefits:

• Roller lever actuator reduces actuation wear for smoother operation
• SPCO contact arrangement enables simple changeover control
• 5A contact rating supports moderate current switching tasks
• 250V AC rated contacts permit use in common AC circuits
• Solder terminals allow Compact PCB or wiring connections
• 10 million operation mechanical life minimises replacement frequency

Applications

• Suitable for limit detection in industrial automation equipment
• Ideal for end-stop sensing in small electromechanical devices
• Used for position feedback in consumer appliance mechanisms
• Can be used for interlock switching in control panels

What materials are used for the external housing and why?

The housing is MADE from phenolic material, offering good dielectric properties and dimensional stability for Compact switching components.

How does the actuator force affect installation choices?

With an operating force of 0.58 N, the actuator requires low input effort, allowing integration with light mechanical linkages and low-torque cams.

What temperature ranges can the device endure during operation?

The component is specified for operation at temperatures up to 121 °C and down to −121 °C, enabling use in environments with elevated thermal conditions.

Which approvals support safety and regulatory considerations?

It carries multiple standards approvals including RoHS, CSA, UL and CE for broad regulatory acceptance across regions.
