The A3SSCB-6AAB-111 is a 3-position selector switch with spring-return to center, cam-operated, configured with one normally-open and one normally-closed contact (1EA-1NC). This is a panel-mount control device for industrial machinery, used to select modes or initiate sequences where the operator must release back to a neutral position.
For a BOM line that depends on the A3SSCB-6AAB-111, the procurement path is the secondary market. No last-time-buy window remains open.
The description breaks down as: SEL 3POS — a selector switch with three positions; L-SPRINGRTN — spring return to the left (center-off) position; CAM C — cam-operated contact block; 1EA-1NC — one early-make (EA) normally-open and one normally-closed contact. The spring-return action means the operator must hold the switch in the momentary position; releasing it returns to the center off-state.
