The SZW26/LW2620 is a 2pole, 3position panel mounted cam switch designed for reliable manual control and transfer between two circuits in electrical panels. It features an ON OFF ON changeover action, a Ui rating of 660 V, and Ith of 20 A, making it suitable for control and power routing within compact panel spaces. With eight screw terminals for wiring and a 48 x 48 mm panel cutout, this switch provides a solid, easytoinstall solution for panel applications that require simple twocircuit selection and safe isolation. Key benefits Enables twocircuit transfer with a single control: ON positions connect the common to one circuit, the other ON position connects to the alternate circuit, with OFF providing isolation. Safe, compact panel mounting: designed for a 48 x 48 mm panel cutout, ideal for tight control panels. Robust electrical ratings for control circuits: Ith 20 A and Ui 660 V support common industrial control needs. Secure wiring: eight screws provide reliable terminal connections for multiple wiring configurations. Simple manual operation: straightforward ON OFF ON action for quick, recognisable control. Key attributes Model: SZW26/LW2620 Poles: 2 Positions: 3 (ONOFFON) Type: Panel transfer (changeover) cam switch Ui: 660 V Ith: 20 A Terminals: 8 screws Panel cutout: 48 x 48 mm Mounting: Panel mounted Applications / use cases Control panels in industrial machinery: use to isolate and switch between two power rails or control circuits from a single actuator, enabling maintenance with the circuit safely isolated. Source selection in equipment: switch between primary and secondary power sources or between two different control circuits in a machine, using the same control handle. Testing and development benches: route power or signals to different devices easily by selecting the desired path with the ONOFFON positions.
