The HZ5B-10/D008.2 is a three-position (1-0-2), two-section (two-layer) manual combination switch with a rated current of 10A. It employs a clearly defined mechanical positioning structure, allowing the handle to stably stop at three positions, each corresponding to a different on/off state of the contacts. This switch is suitable for low-voltage electrical circuits requiring clear and stable control logic, enabling the selection and safe isolation of two circuits.
