Frequently Asked Questions

Q: What does the 1NC configuration mean on this emergency stop button switch?

A: "1NC" stands for 1 Normally Closed contact. In its default (unpressed) state, the circuit is closed and current flows normally. When the mushroom head is pressed, the contact opens and interrupts the circuit, stopping the connected equipment immediately. This is the standard configuration for emergency stop switches used in industrial and CNC control systems.

Q: How do I reset the switch after pressing the emergency stop button?

A: This switch uses a latching (maintained) mechanism, meaning it stays locked in the pressed/off position after activation. To reset, simply press the mushroom head down slightly and rotate it in the direction shown by the arrow indicator on the button head. It will spring back to the released position, restoring circuit continuity.

Q: Is this E-stop button switch compatible with 240V systems?

A: Yes. The switch is rated for 110V to 400V, making it fully compatible with 240V single-phase and many three-phase industrial systems. With a 10A current rating and 1000V dielectric strength, it offers reliable performance across a broad range of electrical control applications.

Q: What panel cutout size is required to install this emergency stop switch?

A: This switch requires a standard 22mm diameter mounting hole — a common size found on most commercial and industrial control panels, enclosures, and CNC machine housings, making installation straightforward without special tooling.
