Yeelight Xiaomi lamp controller with bell button - which one?

I have 4 Yeelight Xiaomi lights. They need to be live all the time to work properly. I can use a flex switch button to switch them on, but the design doesn't suit me. I can use a bell button, but pressing it too long will cause the lamps to go out and light up again when I let go of the button. Are there controls that, when energised by a bell button, will disconnect my circuit for a fraction of a second, no matter how long the button is pressed?
