DZ-10GW2 Double Circuit Micro Switch 10A 220VAC 2NO 2NC
DZ-10GW2 Double Circuit Micro Switch 10A 220VAC 2NO 2NC
DZ-10GW2 Double Circuit Micro Switch – 10A 220VAC, Two Open / Two Close
The DZ-10GW2 double circuit micro switch is a precision-built limit switch designed for industrial automation, machinery control, and electrical engineering applications. With a robust 10A / 220VAC rating and a dual-circuit (two normally open / two normally close) configuration, it delivers reliable position detection and actuation in demanding environments. Compatible with models DZ-10GW, DZ-10GW2-1B, GW21, GW22, and GW-1B, this switch features two sets of travel contacts for versatile installation.
Made in Mainland China.

Frequently Asked Questions
Q: What does "two open and two close" mean on the DZ-10GW2 micro switch?
A: "Two open and two close" refers to the switch's double-circuit contact configuration — it has two normally open (NO) contacts and two normally close (NC) contacts. This allows simultaneous control of two independent circuits, making it ideal for complex automation and limit-switching applications where multiple signals are needed at the same trigger point.
Q: Is the DZ-10GW2 compatible with DZ-10GW, GW21, GW22, and GW-1B models?
A: Yes. The DZ-10GW2 series is designed for cross-compatibility with several related model numbers including DZ-10GW, DZ-10GW2-1B, GW21, GW22, and GW-1B. Always verify the contact configuration, travel actuation type, and mounting dimensions against your existing installation before replacing a switch.
Q: What types of equipment commonly use a double circuit micro switch like the DZ-10GW2?
A: Double circuit micro switches are widely used in industrial machinery, CNC equipment, elevator systems, conveyor belts, gate and garage door automation, and robotic actuators. The dual-circuit design allows engineers to trigger two separate electrical signals simultaneously — for example, stopping a motor while also signaling a control panel.
Q: What is the maximum load this micro switch can handle?
A: The DZ-10GW2 is rated for 10A at 220VAC, which covers a broad range of industrial control applications. Always ensure your application does not exceed these ratings to maintain safe and reliable operation.
