Molded transparent silicone keypad button with radium carving

A transparent silicone keypad button with engraved detail should be evaluated within its finished panel. Nearby supports, surface residue and the background beneath the key can affect how the marking appears even when the molded part is clear.

ETOL offers custom dimensions, shapes, colors and identification features. Align the engraving with the exposed key area and keep structural elements clear of any intended light path. Check the viewing angle used by the product's operator rather than judging only a straight-on loose sample.

During assembly, protect the face and underside from scratches and contamination. Evaluate the button's movement and electrical response separately from its appearance. If illumination is used, inspect the complete arrangement with the lighting active and inactive. During cleaning, use a method compatible with the chosen silicone and marking construction. A cloudy or damaged area should prompt inspection for rubbing or unsuitable cleaning exposure before replacement. Correct the cause so the new key does not develop the same visual interference at its contact with the housing.
