Built-in mechanical relays DC solid state relay GZQ-06


  • Optoelectronic and transformer isolation between control signals and output circuits.
  • Control signal interface with PLC and TTL logic.
  • Light Emitting Diode (LED) indicates working status.
  • Composite switches have arc extinguishing capabilities, extending the lifespan of the switch.
  • Built-in over-voltage absorption protection to prevent transient high voltage from breaking down the solid-state switch.
  • Epoxy resin encapsulation, anti-corrosion, fire-resistant, and shockproof, ensuring stable and reliable operation.


The product is mainly used in medium and small power DC appliances in new energy vehicles, such as PTC heaters, battery charging and discharging systems, solenoid valves, motors, and other switching applications.

Q:What is a composite switch?
A:Combination of Contactless and Contact-Based Technologies: By integrating contactless and contact-based technologies, composite switches can offer rapid switching and long-term reliability. The contactless part allows for quick response, while the contact-based part provides a physical connection when necessary.
