Does anyone know where doorbell pushbuttons are available that have long life, 50 or more years. Likely contacts might be --- reed switch, solid state contact magnetically operated from pushbutton, 50 millionths gold over nickel, possibly silver, or other suitable material. Gold over nickel would have no appreciable influence on price other than marketing people would probably inflate the price.
An AB reed switch would do it, but it is huge.
