Explore Moujen industrial switches at Wallco Inc., including heavy-duty and compact limit switches, enclosed limit switches, micro switches, miniature switches and industrial control devices. Moujen switches are designed for machine position detection, end-of-travel sensing, industrial automation and OEM equipment.

Available product families include M4 compact limit switches, ME and MEA enclosed limit switches, and MJ and MJ1 heavy-duty limit switches. Choose from plunger, roller lever, side-rotary and other actuator configurations to match your application's mechanical and electrical requirements.

Selecting Moujen Industrial Switches

Select a Moujen switch by matching the mechanical interface first. Determine the target motion, actuator style, operating direction, available overtravel and mounting requirements. A switch can have the correct electrical rating and still be unsuitable if the actuator cannot be operated reliably by the machine.

Next, verify the electrical and environmental requirements. Depending on the product family, Moujen provides different contact configurations, current and voltage ratings, environmental protection ratings, positive-opening mechanisms, cable or conduit entry options, and product approvals.

For replacement applications, use the complete Moujen part number whenever possible. Similar actuator styles may be available with different housings, mounting dimensions and contact configurations. Confirm the complete specifications before selecting a replacement.

Frequently Asked Questions

What is Moujen known for?

Moujen manufactures electromechanical control products, including industrial limit switches, micro switches, pushbuttons and industrial control devices used in automation and machinery applications.

How do I choose a Moujen limit switch?

Start by matching the actuator style and mechanical travel requirements to your application. Then verify the contact configuration, electrical ratings, environmental protection, mounting dimensions, cable or conduit entry, and any applicable safety requirements.

What does positive opening mean on a Moujen switch?

Positive opening refers to a switch mechanism designed to mechanically force a normally closed contact open through direct actuator movement. This feature is important in certain machine safety applications. Always verify that the selected switch meets the applicable safety requirements.
