The long wait is over... finally there is a decent tactile low profile keyboard switch!

We call it the Sunset switch, and it is the first truly new Choc switch in years. Designed by LowproKB and manufactured by Kailh, the Sunset switch sets a new standard for low profile tactile switches.

The Sunset tactile switch has a completely redesigned stem which produces the tactile bump and actuates the switch. It comes factory-lubed and ready to add to your keyboard project.

Spec Update

After the Kailh engineers performed long-term switch actuation tests on the Sunset switch, it was determined that there were issues with reliability after a period of time much shorter than the rated actuations. They have estimated that the premature failure rate will be around 80% at the current specification. As such it was decided to increase the operation force to 40gf to allow the Sunset switch to achieve it's rated actuations without failure over time. This makes the switch slightly heavier, but in practice it is hardly noticeable.

It is actually fairly difficult to produce a nice tactile feedback in a short-throw, low profile switch such as a Kailh Choc. This switch is the result of over a year spent iterating through designs trying to find the right balance. Working closely with Kailh engineers, we feel we have found the sweet spot, and think it will be enjoyed by those who love tactile key switches.

The tactile event (bump) of the Sunset switch can be described as "short and sweet", as it is technically impossible to make a smooth rounded bump on a switch with such a short travel. The switch activates just after the bump, but in practice, it feels essentially instantaneous. Those who had the opportunity to test prototypes, did not describe sensing a lag in actuation.
