Snaptron Inc. has developed a new metal tactile dome switch that features dual switching properties. This patent-pending DT Series switch allows users to apply low-level force to engage one switch function and a greater force to engage the second. According to Snaptron, the switches, using IntelliTac technology, boast over 5 million cycles per piece.
The DT06180 is a 6-mm contact switch requiring 120g of force for the first connection and 180g for the second. The DT08400, an 8.5-mm contact switch, requires 280g of force for the first connection and 400g for the second. Snaptron Inc. recently added 10- and 12-mm pieces to the line.
Applications for these switches include still and video cameras, camcorders, camera phones, electro-medical devices and audio equipment. Price varies by size and quantity, but price based on a 10,000-piece order can range from $.12 – $.15 per piece.
In many engineering workplaces, there’s a generational conflict between recent engineering graduates and older, more experienced engineers. However, a recent study published in the psychology journal Cognition suggests that both may have something to learn from another group: 4 year olds.
Conventional wisdom holds that MIT, Cal Tech, and Stanford are three of the country’s best undergraduate engineering schools. Unfortunately, when conventional wisdom visits the topic of best engineering schools, it too often leaves out some of the most distinguished programs that don’t happen to offer PhD-level degrees.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
