Custom made waterproof silk-printing numeric keypad

A numeric keypad uses a defined arrangement of number keys for entering values or commands. Silk-printed legends should remain readable at their finished size and in the panel's normal viewing position. The key pattern must also register with the underlying input mechanism so the visible numbers correspond to the intended entries.

For a waterproof design, the keypad surface is only part of the enclosure arrangement. Perimeter joints, cable exits and adjacent openings also need appropriate construction and evaluation. Printed markings or a flexible rubber sheet do not establish an ingress rating for the assembled device.

Check individual keys and repeated entry with the enclosure fully assembled. The housing should not pinch a key or hold an active area against its contact. During care, preserve the printed surface and keep residue from accumulating along moving edges. Inspect a removed sheet before refitting it, restoring its original orientation so both the numerical layout and any perimeter contact remain correctly positioned within the panel.
