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.
An in-depth survey of 700 current and future users of 3D printing holds few surprises, but results emphasize some major trends already in progress. Two standouts are the big growth in end-use parts and metal additive manufacturing (AM) most respondents expect.
