membrane switch backlighting

tactile membrane switchEmbedded System DevelopmentComplete specifications

A tactile membrane switch embeds a metal elastic dome or silicone rubber keypad combined with conductive carbon pills molding into keys or buttons appropriate elastic response. As plastic overlay for this membrane switch, under this top overlay , there is many metal domes to enhance its tactile properties for its keys or buttons. These domes can be made of conductive materials, maybe it is designed into arch with four feet so that being convenient for user to press down.    When user press down one dome, Dome contact with underneath circuit layer,  close electric circuit. Release the dome, circuit disconnected.  By dome’s tactile property, it will control circuit connection and disconnection completely. In most applications for membrane switch field, such tactile membrane switch is most !
