Product Description

HMX FJ400 Linear Switch

The HMX FJ400 Linear Switch is designed for those who appreciate a balanced auditory experience in their typing. Known for its medium clack, this switch offers a sound that is noticeable but not overpowering, making it suitable for varied typing environments. With an actuation force of 50g and a bottom-out force of 58g, it strikes a comfortable medium weight, allowing for extended typing sessions without fatigue.

This switch features a T2 stem, a Polycarbonate (PC) top housing, and a P2 (Nylon) bottom housing, which collectively produce a deep, full sound when bottoming out. It also includes a 22mm single-stage spring that enhances keystroke consistency. Each switch is factory-lubed with a mixture of GPL105 and GPL205 lubricants, ensuring smooth actuation right out of the box. The 5-pin PCB mount provides stable compatibility for custom builds.
