ITT Industries, Cannon (www.ittcannon.com) has introduced a 4-mm diameter dome switch capable of up to 2.5 million operations, compared to the dome life cycle of 250,000 to 500,000 operations typically required for cell phones. The company says the difference is important to cell phone makers who are incorporating gaming functions into 3G and WAP phones, thus demanding longer dome life. Keys to the new dome's performance include the nominal actuating trip force of 160g, which was exceeded by nearly fourfold (600g) during testing, the company says.
