HZ5B10/D101.1 10A ON OFF ON 4 Screw Rotary Knob Three Position One Pole Combination Changeover Switch Overview The HZ5B10/D101.1 is a threeposition, singlepole changeover switch with a rotary knob and fourscrew terminals. It is rated for 10A and provides ONOFFON operation. This is a compact, combination changeover switch designed for panel mounting and general control circuits that require simple selection between two circuits or sources with a centered OFF position. Key benefits Simple twoway selection with center OFF: enables quick switching between two circuits or power sources while safely isolating the circuit in the OFF position. Easy manual operation: rotary knob offers intuitive control and tactile feedback for reliable use in control panels. Secure wiring: fourscrew terminal configuration supports stable, robust connections and straightforward installation. Spaceefficient design: singlepole, threeposition switch reduces panel footprint while delivering clear, unambiguous states. Key attributes Model: HZ5B10/D101.1 Type: Rotary knob, threeposition, onepole combination changeover switch Positions: ON OFF ON Current rating: 10A Terminals: four screws Operation: manual rotary knob Configuration: threeposition, onepole changeover (SPDT) Applications: suitable for panel control and generalpurpose switching where two outputs are alternately connected to a common input Compatibility: designed for standard wiring in control panels and equipment that require a twooutput selection with an OFF state Construction: designed for reliable electrical switching in a compact form factor in line with the product's brand and specification set Use cases and applications Control cabinet power routing: select between two loads (LOAD A or LOAD B) from a single power source, with OFF when maintenance or testing is required. Bench test and development setups: route signals or power to alternate circuits in a test bench, enabling quick reconfiguration without rewiring. Small equipment backup switchover: manually switch between primary and secondary circuits in compact machinery, providing a simple changeover with an OFF state for safety during service. Notes Ensure wiring adheres to the current rating of 10A and the voltage limits specified for the installation environment. Use appropriate enclosure and mounting practices to protect the switch and wiring. Torque terminal screws to the recommended specifications to maintain secure connections.
