The SZW2620/D303.3 is a 1 piece rotate to select CAM transfer switch with 3 positions (102) and 12 terminals, designed for use in electrical control and power routing applications. It comes with a box for convenient mounting and protection. The rotary CAM mechanism provides positive and repeatable changeover between circuits, with an off position in the middle for safe maintenance. Key features and benefits Three position selector: 102 arrangement with an off position (0) for safe disconnection during servicing or when switching is not required. CAM transfer action: rotary mechanism delivers reliable, positive circuit changeover suitable for control and power routing tasks. 12 terminals: ample wiring terminals to support flexible wiring configurations and multiple connections. Voltage and current rating: rated for AC up to 660 V and 20 A, enabling use in standard industrial and control panel environments. Box included: delivered with a box for convenient installation, protection, and mounting in equipment or control panels. Compact, simple design: straightforward mechanical operation and compact footprint suitable for panel mounting and integration. Technical attributes Model: SZW2620/D303.3 Type: rotate select CAM transfer switch Positions: 3 (102) Terminals: 12 Rated voltage: AC 660 V (maximum) Rated current: 20 A Enclosure: with box Use cases and applications Power source selection in a control panel: quickly switch between two power sources (positions 1 and 2) while using the center off position to safely isolate circuits for maintenance. Test bench routing: route a load to different test circuits or measurement devices by rotating the switch to the desired position, with an off option to stop all connections during setup. Industrial equipment servicing: isolate one circuit while working on another, reducing the risk of accidental energization during repairs or routine service. What you get 1 x SZW2620/D303.3 rotate select CAM transfer switch with 12 terminals 1 x box for installation and protection This switch provides a reliable, straightforward solution for selecting between two circuits with a safe off position, suitable for control panels, testing setups, and industrial equipment where a compact rotary transfer switch is needed.
