Molded colored silicone rubber switch buttons with radium carving

Colored silicone rubber switch buttons with engraved details should present a clear legend within the visible key area. The relationship between the color surface, marking and housing opening determines what remains readable after assembly.

ETOL can customize shape, dimensions, colors and identification features. Position the legend away from heavily curved or flexing regions, and align each key with the underlying actuation point. A visually centered mark should accompany a mechanically centered key.

Inspect the assembled control from its normal viewing angle and through the key's full movement. Evaluate response with the intended circuit, checking return and clearance beside the panel edge. If illumination is part of the product, assess the marking with the complete lighting arrangement rather than the button alone. During assembly and cleaning, protect the engraved surface from scratches and incompatible substances. Correct any housing edge that rubs the key before replacement so a new surface is not damaged at the same location during repeated pressing.
