The SZW2564D/3GS is a threepole cam switch rated at 25A with an ONOFFON configuration, designed for power cutoff and control in electrical panels and machinery. It features a rotary knob with changeover capability and 12 terminal screws for wiring. This switch is intended to provide reliable circuit isolation and safe operation in multicircuit control applications, and it supports padlockable operation for lockout/tagout procedures. Key benefits Safe power isolation: ONOFFON switching allows complete disconnect of circuits, enabling maintenance and setup without energizing equipment. Padlockable for safety: Rotary knob is compatible with padlocks to prevent accidental reenergizing during service or maintenance. Multicircuit control: Three poles enable simultaneous control of multiple circuits, suitable for threephase or multicircuit setups. Clear changeover capability: Changeover cam switch design supports switching between two positions/circuits with a single control. Straightforward wiring: 12 terminal screws provide multiple wiring options and clear terminal access for panel installation. Robust control component: Built to handle standard control panel applications with a reliable threepole configuration. Key attributes Model: SZW2564D/3GS Poles: 3 Positions: ONOFFON Current rating: 25A Terminals: 12 screws Actuation: Rotary knob Function: Power cutoff and changeover cam switch Safety feature: Padlock capability for lockout/tagout Applications and use cases Electrical control panels: Isolate and switch three circuits in a control cabinet for testing, maintenance, or routine operation. Machinery and conveyors: Use in motor control circuits to safely disconnect power during service while allowing lockout to prevent accidental startup. Power source changeover: Implement changeover switching in systems that require switching between power sources or rails, ensuring a safe, controlled transition. Notes Padlock inclusion is not specified; the rotary knob is designed to accommodate padlocks for enhanced safety during lockout/tagout procedures.
