Mechanical keyboard for work typing

The Logitech K845 is a full-size corded keyboard with 104 keys and an aluminium top case. It uses linear red mechanical switches tested to 50 million clicks. Adjustable tilt legs offer a 4-8 degree angle for comfort during long sessions.

Aluminium build with adjustable tilt

The metal top plate adds rigidity while keeping a slim front profile. White backlighting provides five selectable patterns for low-light use. A single USB cable handles both power and data with no extra software required.

Quiet linear switches and low heat

Red switches deliver a smooth, linear feel without an audible click, keeping noise low in shared spaces. The wired connection draws minimal power from the USB port. No active cooling is needed, so the keyboard runs silently.
