The A3SSCC-6AAB-111 is a 3-position selector switch with spring-return to center, using a cam mechanism to actuate one normally-open and one normally-closed contact pair. This is a panel-mount control device for machine operation, mode selection, or two-hand run circuits where the switch must return to a neutral position when released.
The description breaks down as a 3-position selector (SEL 3POS) with right-spring-return to center (R-SPRINGRTN), cam-operated contacts (CAM C), and a 1NO+1NC contact configuration. The spring-return means the operator must hold the switch in the right position; releasing it returns the knob to center. This suits momentary-action control schemes like jog, inch, or test modes where the circuit must de-energize when the operator lets go. The cam contact block provides positive opening operation — the contacts are mechanically forced apart, which is a safety consideration for circuits that must reliably break under fault conditions.
Integration Note
Panel-mount selector switch with a standard 22 mm or 30 mm cutout (verify the specific bezel diameter from the nameplate). The cam block mounts behind the panel; wiring is to the screw or cage-clamp terminals on the contact block. Spring-return torque is set at the factory — no field adjustment. For a replacement in an existing panel, match the operator color and legend plate to maintain consistent HMI labeling across the line.
