DC 220V Latching Solenoid with Auxiliary Micro Switch

Dongfa Intelligent, a DC 220V Latching Solenoid with Auxiliary Micro Switch manufacturer in China, develops this solenoid for high voltage switchgear interlocking and circuit breaker cabinet applications. The product combines interlocking actuation with auxiliary position feedback in one assembly. When the push rod moves to the required position, the auxiliary micro switch changes contact state and sends the corresponding status signal to the control or monitoring system, while the spring self-reset structure returns the push rod to its initial position after the coil is de-energized. It is designed for fixed installation inside switchgear and related electrical cabinets.

Core Advantages

1. Auxiliary Micro Switch for Position Feedback

The integrated micro switch changes contact state when the push rod is actuated. The signal can be connected to a control, monitoring, or five-prevention interlocking system for position status confirmation.

2. DC220V Control Voltage

The solenoid is designed for DC220V control power systems commonly used in power plants, substations, and switchgear control circuits. Confirm the control voltage before selection. This DC220V version is not a direct replacement for an AC220V coil.

3. Spring Self-Reset Structure

The built-in spring returns the push rod after the coil is de-energized, supporting automatic reset within the interlocking mechanism.

4. Metal Housing and Chrome-Plated Push Rod

The galvanized metal housing provides enclosure protection for the internal components, while the chrome-plated carbon steel push rod is designed for repeated mechanical movement.

5. Integrated Plug-In Micro Switch Terminals

The auxiliary micro switch uses plug-in terminals for signal connection. Contact configuration should be confirmed according to the control circuit requirements.

Application Scenarios

The DC 220V Latching Solenoid with Auxiliary Micro Switch can be used in electrical equipment requiring mechanical interlocking with position status feedback, including:

• High voltage switchgear interlocking systems
• Circuit breaker cabinet anti-misoperation interlocking
• Five-prevention interlocking systems
• Power plant switchgear control cabinets
• Substation switchgear and control equipment
• Power distribution equipment requiring auxiliary position feedback

Manufacturing & Quality Support

Dongfa Intelligent, founded in 2012 in Yueqing Economic Development Zone, Wenzhou, Zhejiang, manufactures high-voltage electrical equipment and related switchgear components. The company operates dedicated production lines for electrical components and supports OEM/ODM requirements.

For this DC 220V Latching Solenoid with Auxiliary Micro Switch, production inspection includes action characteristic testing and dielectric withstand testing. The linkage between the push rod and auxiliary micro switch is also checked to ensure the feedback contact operates at the required mechanical position.

Supply & Customization

FAQ

What auxiliary micro switch contact types are available?

Common configurations include NO, NC, and NO+NC. The required contact type depends on the control system signal logic and should be confirmed before ordering.

Can a DC220V latching solenoid be used on AC220V power?

No. The DC220V version is designed for DC control power. AC220V and DC220V coils should not be interchanged without confirming the coil design and electrical requirements.

How does the auxiliary micro switch connect to the control system?

The micro switch uses plug-in terminals for signal connection. The contact output can be connected to the applicable control or monitoring circuit after confirming the required contact configuration and electrical rating.

Will the solenoid still operate if the auxiliary micro switch fails?

The DC 220V Latching Solenoid with Auxiliary Micro Switch is used for position signal feedback and is separate from the main solenoid actuation function. However, a failed micro switch will prevent the control system from receiving the corresponding position feedback signal.

What information is required for quotation?

Please provide the operating voltage, auxiliary micro switch contact type, application, mounting dimensions, and quantity. For replacement projects, the original model and push rod dimensions are recommended.
