Moujen specializes in electromechanical control switches for industrial automation, with product families covering heavy-duty, compact, miniature, enclosed and positive-opening limit switches as well as micro switches and panel control devices.
Important Moujen families include M4 compact sealed limit switches, ME and MEA enclosed limit switches, MJ and MJ1 heavy-duty aluminum limit switches, and micro/miniature switch families for smaller mechanisms. Actuator choices across the line include plungers, roller plungers, side-rotary levers, adjustable rods and spring-style actuators.
Moujen switches are used for machine position and end-of-travel detection, conveyor and packaging control, guarding/interlock functions, OEM equipment and other applications where a mechanical movement must produce a dependable electrical contact change.
Select a Moujen switch by matching the mechanical interface first: determine the target motion, actuator style, operating direction, available overtravel and mounting envelope. A switch can have the correct electrical rating and still be wrong if the actuator cannot be driven reliably by the machine.
Next verify the electrical and environmental requirements. Depending on family, Moujen publishes contact forms and current/voltage ratings, IP sealing, positive-opening features, conduit or cable-entry options and approvals such as UL, CSA and CE.
For replacement work, use the full Moujen model number whenever possible. Similar actuator heads can appear across different housings and contact configurations, so series, actuator code and electrical/contact details all matter.
Moujen manufactures electromechanical control products with a strong focus on industrial limit switches, micro switches, pushbuttons and emergency-stop/control devices.
Match the actuator and mechanical travel to the machine, then verify contact form, electrical rating, environmental sealing, cable/conduit entry, mounting dimensions and any positive-opening or safety requirement.
A positive-opening design uses direct mechanical action to force a normally closed contact open. It is used where the application requires that specific safety-contact behavior and should be applied as part of the machine safety design.
