Keyboards are one of the most wear-heavy components of any PC build and usually a single key can ruin a perfectly good gaming keyboard. The reason why all keyboards eventually wear out is because they use mechanical switches whose mechanism eventually breaks down. This is a problem that is going to be there for pretty much any switch that uses a membrane or plastic mechanism. HP’s OMEN Sequencer keyboard is a work of art, built of one of the finest materials with individual keys guaranteed to last 10x longer than traditional switches.

Optical switches are a pretty new player to the keybaord market and are one of the most significant innovations in keyboard tech for pretty much the last decade. Using light as the actual swtich means any commands are transmitted instantly with zero input lag. For gaming purposes this is the absolute ultimate in input technology. The HP Omen Sequencer keyboard makes use of blue optical mechanical switches for the perfec blend of technology and experience.
