YINGHUA K1Button Exit Push Button Door Lock

The YINGHUA K1Button is an exit push button release switch designed for door access control systems. It suits installers and facility managers who need a reliable contact interface for electric locks. The unit provides NO, NC and COM output contacts for flexible wiring. It operates on a DC 12-36V supply rated at 3A.

Build quality and daily mounting implications

The panel uses hard plastic with a SUS 304 stainless steel plate rated to IP55 ingress protection. Infrared touch sensing allows hands-free operation, reducing surface contact in shared spaces. Mechanical life is tested to 500000 cycles for long-term durability. Dimensions are 90.5 by 86 by 30mm and weight is 125g for standard mounting.

What this replaces and when the upgrade makes sense

This button replaces traditional mechanical exit switches that require physical pressure and wear faster. The jump is worthwhile where touch-free operation improves hygiene or where IP55 protection is needed against dust and water jets. It is not suited for installations needing wireless connectivity or battery-powered standalone function.

Questions about this item

Does the push button support both normally open and normally closed wiring?

Yes, the switch provides NO, NC and COM contacts so you can wire it either way for your access controller.

Will the 90.5 by 86 millimetre panel fit a standard UK single-gang back box?

The panel measures 90.5 by 86 millimetres, matching the common single-gang footprint used in UK installations.

How do I connect the 12 to 36 volt DC supply without damaging the LED?

Wire the supply to the COM and either NO or NC terminal; the built-in LED is rated for the full 12 to 36 volt range so no external resistor is needed.
