Romer-G switches are mechanical keyboard switches used exclusively on Logitech mechanical keyboards. The Romer-G switch was first unveiled in the Logitech G910 Mechanical Gaming Keyboard back in 2014 as a joint development between Logitech and Omron, which manufactures the Romer-G switch. Compared to the Cherry MX switch, the Logitech Romer-G switch features a shorter travel distance, shorter actuation distance and a light guide in the center of the switch. Logitech Romer-G switches also feature dual actuation contact points making it more accurate and mores durable compared to mechanical switches with a single actuation contact point.
