Snaptron Launches the RCG Series, A Tactile Dome Switch that Activates Multiple Independent Circuits and Reduces the Impact from Debris

The unique design of the RCG tactile dome can maintain electrical contact despite the possible impediment of debris. A low profile, life ratings of up to 5,000,000 cycles, and custom options make the RCG dome an ideal switch solution for engineers.

The RCG series solves a variety of problems for our customers but was designed with the overarching goal—to decrease the chances of contact failures

Today Snaptron announced the launch of a brand-new series of metal domes, the RCG series, a four-legged dome with a unique ring in the center. This feature helps reduce impact from contamination, assembly tolerances, or off-centered presses, making it the most versatile metal dome switch on the market.

The RCG series dome addresses a crucial pain point for customers, loss of electrical contact between the dome and board due to the buildup of debris. The “ring” feature provides a 360-degree ring of contact, which minimizes the impact from contaminants. When debris obstructs the circuit in one area, the ring still makes contact in another area. This feature on the dome also ensures that electrical contact is maintained even with off-center or off-angle actuations.

Another stand out feature of the RCG dome is its ability to activate multiple independent circuits. As systems continue to become smaller, engineers must make difficult decisions regarding component space and functionality. Because most dome designs only make contact at a single point in the center, the design typically only allows for a single contact pad and a single circuit closure. A fingered center pad allows for two or more circuits to be contacted at the same time by multiple parts of the ring so that multiple circuits can be activated, even if the actuator makes uneven contact.

“The RCG series solves a variety of problems for our customers but was designed with the overarching goal—to decrease the chances of contact failures,” said Ashley Steinbach, Director of Strategic Development. “Our customers have come to know and rely on the high-quality domes and customer experience we provide. The RCG dome is another high-value addition to our product line up that we know brings even more value to our customers’ end-use applications.”

The RCG dome offers a low profile, high life cycle rating, multiple custom options, tactile and acoustic feedback, and a comprehensive range of forces compared to other switch technologies. The RCG dome is a top switch solution that engineers can seamlessly design into a wide variety of applications.

The RCG dome comes standard in 5.3, 6.3, 7, 8.5, 10, and 12 mm sizes with forces ranging from 200g to 500g, depending on diameter, and life ratings up to 5,000,000 cycles. All standard RCG domes are nickel plated. For custom options regarding size, force and style, contact Snaptron or visit http://www.snaptron.com/rcg-series for additional information.
