DuraSwitch Receives Expanded Patent Coverage on its Electronic Switch Products

Business Wire, Oct 1, 1998

PHOENIX--(BUSINESS WIRE)--Oct. 1, 1998--The U.S. Patent Office has granted DuraSwitch(R) Industries Inc. (OTC BB:DSWT) a third patent covering detailed refinements to the technology developed for its electronic switch products, DuraSwitch Chief Executive Officer Terren Dunlap announced.

The latest refinements strengthen the manufacturing and licensing of the DuraSwitch(R) technology, which incorporates rotary, pushbutton and slide switches into flat-panel designs. DuraSwitch engineers, manufactures and markets integrated controls panels that provide customers and users with the familiar "click" and physical feedback desired in a switch.

"The most recently patented refinements and concepts are designed to improve the mass marketing of the DuraSwitch technology," said Anthony Van Zeeland, DuraSwitch COO/EVP of Engineering and creator of its patented product designs. "We now have an ultra-high reliability detent mechanism that is custom-tooled with minimal cost, as well as a rotary switch or potentiometer kit that can be 'snapped' onto a membrane switch."

One DuraSwitch design, the PushGate(TM), has been tested beyond 90 million actuations to date, far exceeding other tactile pushbutton switches. DuraSwitch is currently manufacturing the DuraSwitch PushGate(TM) into products used by Fortune 500 companies.

In addition to the newest patent, DuraSwitch also develops its integrated electronic switch panels under U.S. Patents 5,523,730 and 5,666,096.
