Regardless, as a momentary switch, must contain a Membrane Layer and a Static Layer.All other layers required for decoration, backlighting, adhesive, tactile response and rigid support are all optional.<\/p>\n<p>Please see below\u00a0a short explanation of five basic layers of a membrane switch:<br \/>\n1. GRAPHIC LAYER:<br \/>\nDecoration of a membrane switch is conventionally accomplished with thin, screen printed, polyester or polycarbonate. Elastomer is also a method of decorating a switch assembly and an attractive and functional alternative especially when a three dimensional look and feel is desired.<br \/>\n2. MEMBRANE LAYER:<br \/>\nAs discussed above the Membrane Layer is thin &amp; pliable and carries at least one of the poles of the switch or carries a conductive shorting pad. This is a required layer. Materials used are: Polyester, <a title=\"metal dome\" href=\"https:\/\/www.china-metaldome.com\/\" target=\"_blank\">Metal Dome<\/a>, Elastomer, Polyimide.<br \/>\n3. TACTILE LAYER:<br \/>\nThere are several ways to create a tactile response, some are a result of forming another layer. For example a dome embossed polyester overlay means the graphic layer is also the tactile layer. If a poly dome is formed in the membrane layer means it doubles as the tactile layer. Obviously if the tactile layer is absent, you have a non-tactile membrane switch. Options for Tactile Layers are <a title=\"metal dome\" href=\"https:\/\/www.china-metaldome.com\/metal-dome.html\" target=\"_blank\">Metal Dome<\/a>, Polyester Dome, Dome Emboss in the Graphic Layer, Elastomer.<br \/>\n4. STATIC LAYER:<br \/>\nThe Static Layer is rigidly supported and carries at least one of the poles of the switch or carries a conductive shorting pad. The Static Layer is a required component of a membrane switch. Polyester,\u00a0 transparent conductor &#8211; ITO, Polyimide, <a title=\"printed circuit board\" href=\"https:\/\/www.flexiblecircuitpcb.com\" target=\"_blank\">Printed Circuit Board<\/a>.<br \/>\n5. RIGID LAYER:<br \/>\nIf the static layer is made from a flexible material it must be laminated to a rigid material. Many membrane switches are purchased without a rigid backer and the static layer does not become truly static until it is attached permanently to the instrument housing. Example materials: Aluminum, Steel, Plastic, Glass, Fiberglass<\/p>\n<p>Ok, you can see the membrane switch construction as below:<br \/>\n<img decoding=\"async\" src=\"https:\/\/www.china-metaldome.com\/blog\/wp-content\/uploads\/2010\/Membrane-Switch-Construction.jpg\" alt=\"Membrane switch construction\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A Membrane Switch can be as simple as a two layer construction or a multi-layered complicated assembly.
