SZW26/LW2620/04.4 20A 660V 4 Poles 16 Terminals 48X48 mm Panel Changeover Rotary Selector Cam Switch Key benefits Reliable manual changeover and circuit selection: the camstyle rotary selector provides clear, positive switching positions for selecting circuits or changing sources by hand. capacity switching in a compact form: rated for 20 A at up to 660 V, this 4pole switch handles multiple circuits simultaneously while fitting a 48 x 48 mm panel cutout. Flexible wiring and installation: 16 terminals support a variety of wiring schemes and make it straightforward to integrate into control panels and distribution setups. What it does and why you need it The SZW26/LW2620/04.4 is a panelmounted changeover rotary selector cam switch designed to switch up to four poles at once, enabling isolation or selection of multiple conductors with a single control action. It is ideal where dependable manual switching and compact panel footprint are required. Key attributes Model: SZW26/LW2620/04.4 Rated current: 20 A Rated voltage: 660 V Poles: 4 poles (simultaneous switching of four circuits) Terminals: 16 terminals for versatile wiring configurations Panel size: designed for a 48 x 48 mm panel cutout Function: panel changeover rotary selector cam switch Performance and compatibility Supports up to 20 A per rating and switching up to 660 V, suitable for many control and distribution applications. Four poles allow coordinated switching of multiple phases or circuits from one selector. Sixteen terminals give installers flexibility when connecting inputs, outputs, and auxiliary circuits. Compatible with standard industrial control panels that accept a 48 x 48 mm cutout. Typical use cases Manual transfer between two power sources or feeders in small distribution and control panels. Use the selector to change supply routing safely and clearly. Selecting motor control modes or isolating motor windings in machinery control cabinets where coordinated multipole switching is needed. Circuit selection and testing in electrical maintenance panels, where rapid, repeatable changeover between circuits is required. Practical notes for installers Ensure panel cutout matches the specified 48 x 48 mm dimension for correct fit and sealing. Plan wiring to make use of the 16 terminals for neat and logical connections, labeling each terminal to match panel schematics. Confirm the 20 A and 660 V ratings meet the requirements of your application before installation. This SZW26/LW2620/04.4 cam switch offers a compact, straightforward solution for manual changeover and multicircuit selection where reliable switching and flexible wiring are required.
