Standard Keycaps

Signature Plastics specializes in two shot insert molded keycaps. While most customers prefer two shot molded keycaps due to the legend resistance to long-term finger wear, we also offer sublimation printed keys and pad printed keys.  Signature Plastics manufactures a variety of standard keycap families, each with their own distinguishing characteristics.

Family profiles can be low, medium, or high with a sculptured or non-sculptured look. Touch area finishes are typically semi-gloss or matte. The touch area itself may be either spherical, cylindrical or flat. A wide variety of keycap sizes are available, as well as specialty keys, such as J or L shapes, stepped keys, lens keys, homing bar or homing bump keys, block keys, and space bars. A wide assortment of molded in mount details are also available, depending on the type of key switch being used.
