Editing Fujitsu Leaf Spring (section)

==History==
The Fujitsu Leaf Spring switch seems to have been developed in the late 1970's as a way to reduce manufacturing costs for contact-based keyboard switch mechanisms (as opposed to sense-based mechanisms such as Hall Effect). The first iteration of the switch design used individual housings, and could be used individually, provided the switch is inserted into a stabilizing plate. The second design still used individual barrels for the switches, but it relied on the plate to suspend them over the leaf spring, similar to how [[IBM]] [[IBM Model F|Model F]] [[Switch terminology#Capacitive Contact Mechanism|capacitive]] [[Buckling Spring|buckling spring]] keyboards were designed. There is one confirmed keyboard that uses a one piece slider assembly, similar to the way the [[IBM]] [[Model M]] keyboard is designed.{{citation needed}}

There is also a known tactile version of the 3rd generation of the Fujitsu Leaf Spring switch. Though due to the design (the mechanism is inside the slider barrel), this newer design could be used in 2nd generation housings. Unfortunately, keyboards with this tactile switch are much more rare than the linear variants.

These switches are most famously used in the [[FM Towns]] line of keyboards as well as the [[Tandy 1000]] keyboards.
