YINGHUA K2Button Exit Push Button

The YINGHUA K2Button is a door exit push button designed for access control systems. It operates on DC 12-36V at 3A with NO, NC and COM output contacts. The unit measures 90.5 by 86 by 30 millimetres and weighs 125 grams. An integrated LED light provides visual status indication for entry points.

Simple two-wire installation suits DIY fitters

Wiring connects to the clearly marked NO, NC and COM terminals on the rear of the switch. The hard plastic panel mounts on a standard back box with supplied screws. The most common issue is reversing the normally open and normally closed wires, which keeps the lock energised when the button is released. IP55 rating protects the internals from dust and water jets during cleaning.

Ideal for offices and communal doors needing

The infrared sensor allows hands-free operation, reducing contact points in high-traffic areas. Mechanical life is rated at 500000 cycles for long-term reliability. Buyers who need a weatherproof keypad or a card reader for secure entry should look at a different product type. The stainless steel 304 faceplate resists corrosion in indoor and covered outdoor locations.

Questions about this item

How do I confirm the button is working after wiring it to the access controller?

Press the button; the LED should light and the lock must release. Release the button and the lock should re-engage after the controller’s timed delay.

What comes in the box and what extra parts are needed?

The push-button unit with NO, NC and COM terminals is included. You must supply a 12–36 V DC power source, an electric lock and the access controller separately.

Which version should I choose for an outdoor gate?

Select the K2Button model with the IP55-rated stainless-steel plate; it matches the 90.5×86×30 mm size and 500000-cycle mechanical life listed for exterior use.
