What is a Membrane Switch?

Author:admin    From:Admin5    Pubdate:2015-06-26 22:52    Page view :
Standard membrane switches are thin, low-profile, micro-motion assemblies, with one or more layers of silver or carbon conductors printed on polyester substrate layers. Pressure-sensitive adhesives are used to bond the layers together. Assemblies can be designed as thin as 1.00mm. Tactile metal domes provide the "snap" or tactile feedback and audible sound when the switch is actuated. Available options include non-tactile membrane switches (ex, microwave ovens, treadmills), poly-domes and silicone rubber keypads with carbon or gold contacts.
 
Membrane switch assemblies incorporate electronic components, such as LEDs, seven-segment LEDs, photo diodes resistors and capacitors that are integrated to the membrane switch substrate using conductive adhesive technology. Hover’s advanced manufacturing can print double-sided silver circuits producing the equivalent of four layer PCBs or the elimination of printed ‘crossovers’ for environmentally exposed applications. These advances are customized in a variety of configurations to fit increasingly smaller, more demanding and cost competitive applications. For higher level integration, Hover has experience and manufacturing to include copper flex circuits and PCB assemblies, LCDs, plastic housings or metal backers and lenses.
Hover’s membrane switches are qualified through tests based on the ASTM (American Society of Testing and Material) standards, conducted in Hover's in-house testing facilities.
