HZ5B10/D101.1 10A ON OFF ON 4 Screw Rotary Knob ThreePosition OnePole Combination Changeover Switch Key benefits Simple, reliable control: Threeposition ON–OFF–ON layout lets you select between two active circuits or a neutral/off position with a single rotary action. Secure electrical connections: Four screw terminals provide firm wiring and stable contact for repeated use. Ready for practical applications: Rated for 10A, this switch is suitable for a wide range of control and selection tasks within the device's current limit. Clear, userfriendly operation: Rotary knob and distinct positions reduce operator error and make function selection quick and intuitive. What it is and why you need it The HZ5B10/D101.1 is a onepole, threeposition changeover switch with an ON–OFF–ON configuration and a rotary knob actuator. It is designed to give straightforward selection between two live outputs with a center off position. Use this switch when you need a compact, easytooperate selector for power routing, mode selection, or circuit testing where a 10A current capacity is sufficient. Key attributes Model: HZ5B10/D101.1 Functionality: Threeposition rotary — ON, OFF, ON (combination changeover) Pole/Throw: One pole (single common contact switching between two throws) Termination: Four screw terminals for secure wiring Current rating: 10A Actuation: Rotary knob for positive, repeatable switching Use cases Equipment mode selector: Choose between two operating modes or sources (for example, two signal paths or two power feeds) with a center off for safe transition and testing. Test benches and prototyping: Quickly switch a single signal or power line between two different circuits or measurement instruments without rewiring. Small appliance or accessory switching: Suitable for routing power or control signals in hobbyist projects, control panels, or accessory circuits that stay within the 10A rating. Installation and safety notes Observe the 10A rating; do not exceed the current to avoid overheating or damage. Ensure power is disconnected before wiring. Tighten screw terminals firmly to secure conductors and prevent intermittent contact. Verify wiring matches the intended ON–OFF–ON function before applying power. Why choose this switch The HZ5B10/D101.1 combines a clear threeposition ON–OFF–ON layout with a robust screwterminal connection and a conventional rotary knob. Its straightforward operation and singlepole changeover design make it a practical choice for applications that require reliable selection between two circuits with a center off position, all within a 10A current capacity.
