ABB SK 616 001-A Selector Switch With Contact Block

ABB SK 616 001-A is a compact 22 mm diameter selector switch with a built-in contact block, finished in a black operator for front-mount control panels. This non-illuminated device is designed for signaling and mode selection in industrial controls and is rated for up to 10 A at 600 VAC, aligning with NEMA A600 circuits. The SK 616 family is modular, and SK 616 001-A can be paired with front-mount contact blocks such as KCB-10 (1 NO) to tailor the switching function without replacing the entire unit. ABB’s accessory catalog describes compatible front-mount options for SK 616 contact blocks, supporting flexible panel layouts and straightforward customization. Typical applications include stop/start and mode-selection tasks in machines, conveyors, and process automation where a robust, hand-operated selector switch is required in a compact footprint. With the appropriate contact block, this selector switch can adapt to evolving control needs while preserving ABB’s reliability and mechanical durability in industrial environments.
