The 3-position configuration is useful when you need to control two separate circuit paths from a single switch.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What do NO and NC mean on this rotary switch?\u003c\/h4\u003e\n\u003cp\u003eA: \u003cstrong\u003eNO (Normally Open)\u003c\/strong\u003e means the circuit is open (disconnected) in the default position and closes when the switch is activated. \u003cstrong\u003eNC (Normally Closed)\u003c\/strong\u003e means the circuit is closed (connected) by default and opens when switched.

The key can only be inserted or removed when the switch is in the \u003cstrong\u003eOFF position\u003c\/strong\u003e. This prevents unauthorized or accidental operation of the circuit while it is active.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What panel cutout size is required for this rotary key switch?\u003c\/h4\u003e\n\u003cp\u003eA: This switch is designed for a standard \u003cstrong\u003e22mm panel cutout\u003c\/strong\u003e, making it compatible with most industrial and hobbyist control enclosures and panels.
