Universal Doorbell Button Cover Plate
This 46 x 110 x 14 mm hollow-back faceplate replaces a cracked wired doorbell button. It covers an old wall cutout up to 40 x 104 mm and takes a 16 mm panel-mount momentary pushbutton in a 16.2 mm through-bore, with a drip hood above it. Two 4.4 mm reinforced slots fit #6 (3.5 mm) or #8 (4.2 mm) screws at any spacing from 40 to 84 mm, so it lines up with old holes. A notch in the bottom wall lets surface-run bell wire in.
