Edge-mounted switch, soldered to printed circuit board, gives direct sliding contact. In the graphic to the bottom left, conventional side push switches typically measure 4.5mm deep and require a mechanical actuator to connect the user button and the dome.
Expanding LCDs on portable electronic equipment leave less board space for switches. That's one reason many of today's handheld devices feature side-push keyblock switches. Precise alignment requirements, however, drive up manufacturing cost and assembly time.
Edge-mounted switches present a low-cost alternative. And, measuring as little as 3.0 mm deep, they save even more board space. Soldered directly to the pcb, these ultra-miniature switches offer long life (to one million cycles), a 0.25- or 0.70-mm stroke, and an operating force from 1 to 5N.

Truchard will be presented the award at the 2014 Golden Mousetrap Awards ceremony during the co-located events Pacific Design & Manufacturing, MD&M West, WestPack, PLASTEC West, Electronics West, ATX West, and AeroCon.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
