Baldham, Germany knitter-switch announces a series of micro-miniature tact switches designed for a variety of applications in industrial automation where an ultra-small, rugged and waterproof switch is required. Called the TMSE series , the switches are RoHS compliant, washable (comparable to a IP65 rating) and feature a long mechanical life (100 000 cycles). The TMSE 10 switches measure just 4.8 x 4.5mm. They are also available in a J-Wing (TMSE 10 J) and side-push version (TMSE 10 J-RA) and feature contacts rated at 24 V DC/100 mA (250 V AC for 1 minute), a contact resistance of 100 mOhms max and an operating force of 3 N. Designed to be leadfree-solderable, the switches feature an operating temperature range of from –55 to +125 °C. The micro-miniature tact switches are available from stock. Samples are usually available on next day delivery. Knitter-Switch , Baldham, Germany. www.knitter-switch.com.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
