MEMBRANE SWITCHES

Membrane switches are aversatile, low cost and reliabletechnology. Combining layers ofpolyester (PET) and acrylic based adhesives with screen printable conductive circuits and graphicoverlays, membrane switchesoffer developers of HumanMachine Interface systems analternative to bulky mechanicalswitches—and they are thin,environmentally robust, and assembly-friendly.

Tactile

TechnologyDescription

OVERVIEW

Tactile feedback in a membraneswitch is actually an enhance- ment, which provides the user feedback when they press thekey location. Typically, the switchconsists of a top and bottomlayer of polyester with a tactileactuator that when pressed, momentarily completes the circuit while providing the user a degree of response based on the switch’s construction.Memtron Input Componentsoffers a variety of proven Tactiletechnologies.

Posi-Tac II: This construction performs well in situationswhere abuse, harsh environmental conditions and errantelectrical charges are inherent. Poly-Tac II: A hybrid switch construction providing tactileresponse through a custom embossed overlay. Cost-effective in applications with highly populated key arrays or insmaller keypads with significant volume requirements. Uni-Tac: A highly cost-effective and proven construction,but with limited tactile applications. Poly-Tac I: A popular and sometimes cost-effectivealternative to stainless steel dome construction. PushGate
® : A unique pushbutton switch that combines the
advantages of discrete mechanical and flat panel membrane switches with a host of other benefits, making it ideal fornext-generation products.
