Structure

The following figure shows the basic structure. Optional design based on the structure described below enables the use of the membrane switch in various applications.

Options

• Chip-mounted membrane
  Highly functional membrane switch on which component devices such as LEDs and diodes are mounted
• Rubber-mounted membrane
  Product lineup includes rubber-mounted membrane switch that provides a tactile feeling for the user
• Graphic sheet
  Printed sheet used for decorative purposes (photographic color printing). Features include metal color-printing, embossing, and the formation of a metal-dome pushbutton actuator mounted on the back.
• Waterproof membrane
  Membrane switch with a simplified waterproof structure in which printed seals and double-sided adhesive sheets are used
• Sheet switch
  Metal-dome or poly-dome mounted membrane switch. Product lineup includes sheet switches combined with a surface panel equipped with an actuator on which various patterns are printed, and those equipped with magnetic devices or lighting LEDs.
