Just received an order from AliXpress of some unusual membrane switches which I am very impressed with.
They come in a variety of styles, with 1, 2, 3, and 4 button configurations. The switch itself is a membrane type dome switch. They are surface mount using a self-adhesive backing and are only 1mm thick, so very unobtrusive when mounted and taking up no space at all inside the case.
I got the grey ones, but there are four colors (and a numeric keypad) available. I have subsequently ordered more colors.
The leads are flex PCB terminated in .1" (2.54mm) female headers which is very convenient. Mounting is simple and clever. A ¼" (6mm) hole allows the connector through the panel, the gap the left side of the cable (in photo) is enough to completely cover the hole. The appearance is very neat.
A quick test shows they are relatively low bounce and the construction suggests that if they are not waterproof, they would still be quite water resistant.
Of course I don't know about longevity yet, but they seem robust and are very inexpensive. I ordered more in case they were no longer available when I needed them.
