Spring return to center means the switch stays in the left or right position only while held — release returns it to the center-off state. That suits momentary control actions like jog, inch, or manual override on a conveyor or machine axis. ## What the 1NO+1NC contact arrangement means for fit The 1NO+1NC contact block gives one set of normally-open and one normally-closed contacts, switched simultaneously by the cam. In a safety or control circuit, the NC pair can be wired as a feedback signal (switch actuated = contact opens) while the NO pair drives the action. That is a common pattern for two-hand control or mode-select interlock schemes. As a panel-mount selector switch, the A3SSCD-6AAB-91 fits a standard 22.5 mm or 30 mm cutout (A3 series footprint). The cam operator and spring-return mechanism are enclosed in the switch body; the 1NO+1NC contact block clips onto the back. Verify the panel thickness and mounting nut clearance before committing the cutout — the A3 series typically accommodates 1–6 mm panels.","metaTitle":"A3SSCD-6AAB-91 A3 Selector Switch, 3-Pos Spring Return, 1NO+","metaDescription":"A3SSCD-6AAB-91 A3 selector switch, 3-position left/right spring return, cam-operated 1NO+1NC contacts.
