How It Works
1
Press to stop
Pressing the mushroom head activates the switch — NC opens, NO closes. The button locks in the depressed position.
2
Machine stops
If wired via the NC contact (recommended), pressing the button cuts the signal or power to your machine immediately.
3
Twist to release
Rotate the mushroom head clockwise until it clicks and pops back up to its normal position.
4
Reset and resume
Reset or restart your machine's controller after releasing the button before resuming operation.
Please note: Wire in accordance with local electrical safety standards. Verify contact ratings match your application before installation. 16mm panel cutout required.

Wiring — 1NO + 1NC Contacts
COM terminalCommon — connect your supply or signal here
NO terminalNormally Open — open at rest, closes when button is pressed & latched
NC terminalNormally Closed — closed at rest, opens when button is pressed & latched
Most e-stop safety circuits use the NC contact. Wire NC in series with your machine's power or enable signal. When the button is pressed, NC opens and cuts power or signal to the machine. This is the fail-safe configuration — a broken wire or loose connection will also trigger a stop.
To release: Twist the mushroom head clockwise until it clicks and pops back up. Then reset your machine's controller before resuming operation. Do not bypass or defeat the e-stop mechanism.
Please note: For mains AC applications, installation must be carried out by a licensed electrician. Wire in accordance with local electrical safety standards.

Common Questions
How do I reset the button after pressing it?
Twist the mushroom head clockwise — it will click and pop back up to its normal position. You'll also need to reset or restart your machine's control system before it will resume operation.
Should I wire the NO or NC contact for my e-stop circuit?
Use the NC contact for safety-critical applications — it's the fail-safe choice. If a wire breaks or comes loose, the NC contact opens and the machine stops. Only use NO if you specifically need the circuit to activate (rather than cut) when the button is pressed.
What size hole do I need to drill?
16mm diameter. The switch mounts through the panel and secures with the included hardware. Panel thickness up to approximately 5mm works well.
Is this suitable for outdoor or wet environments?
The IP65 oil-tight rating makes it suitable for environments with coolant spray, oil mist, or light moisture exposure. It is not rated for full submersion or prolonged direct water exposure.
Please note: Wire in accordance with local electrical safety standards. Verify contact ratings match your application before installation.
