How do I reset the emergency stop button after pressing it?

To reset the emergency stop button, you must firmly grasp the red mushroom head and twist it clockwise following the engraved arrows. The self-locking mechanism will release, allowing the button to pop back up and close the 1NC electrical circuit again.

Can I use this E-stop switch to directly cut power to a heavy 220V motor?

No, you should not use this E-stop to directly cut power to a heavy motor if its startup or stall current exceeds the 10A rating. For heavy machinery, you must wire this 1NC switch to the control coil of an AC contactor, which will then safely handle the heavy motor load.

Why does this emergency stop button have a clear plastic cover?

The clear plastic cover is designed to prevent accidental triggers in busy work environments. Operators must intentionally lift the hinged cover before they can strike the red button, ensuring that bumping into the control panel does not cause unnecessary machine shutdowns.

Can I buy this industrial E-stop switch for my factory in Hong Kong?

Yes, this Emergency Stop Button with Enclosure is in-stock and available for immediate pickup at Sun Cheong Computer Co. Ltd. (新昌電腦有限公司) in Sham Shui Po. We supply reliable safety components to local factories, workshops, and DIY automation enthusiasts.

What does 1NC mean for my wiring setup?

1NC stands for "1 Normally Closed" contact. This means that when the button is untouched, electricity flows freely through the switch. The moment you press the emergency button, the internal contacts separate, breaking the circuit and instantly stopping your connected machinery.

Full Product Description

Reliable Emergency Power Cut-Off for Industrial Safety

This Emergency Stop Button Switch provides an immediate, fail-safe method to cut power to hazardous machinery, protecting both operators and equipment. Utilizing a standard 1NC (Normally Closed) contact block, the switch maintains a continuous electrical circuit during normal operation and instantly breaks the connection the moment the red mushroom head is struck. Rated for a wide voltage range of 6.3V to 400V and a conventional heating current of 6A (10A max), it is highly adaptable for both low-voltage DIY robotics and high-voltage industrial control panels.

Latching Mechanism with Protective Cover

The Latching E-Stop Switch features a secure push-to-lock mechanism that ensures the machine remains powered off until intentionally reset by twisting the button clockwise. To prevent costly production halts caused by accidental bumps, this specific model comes equipped with a clear, hinged protective cover. This transparent shield requires the operator to lift it before striking the button, making it ideal for high-traffic workshops or crowded control stations where unintended triggers are a major concern.

Pro Tip from Our Technicians

When wiring this Emergency Stop Button, our Sham Shui Po technical team strongly advises wiring the 1NC contact in series with the control coil of an AC contactor or a heavy-duty relay, rather than wiring it directly to the main motor load. While the switch is rated for 10A, using it to break the control circuit instead of the main power line prevents electrical arcing inside the switch, drastically extending its lifespan. If you need help designing a safe relay circuit, bring your schematic to our physical store for expert advice!
