Switches made for KBDfans have had their logo embossed on the top.  The T1 were introduced on the store KBDfans marketed as an alternative to the Holy Panda switch. After it had been discovered that KBDfans had been selling fake linear Zeal switches ("Stealios"), and that parts of them had been made by Durock, KBDfans halted sales also of the T1 switch.
The Koala switch had been designed by biip in a cream and dark grey colour scheme to match the Extended 2048 keycap set which had been designed to resemble the style of vintage Apple keyboards, such as the Apple Extended Keyboard. The original switch has a 62gf spring. 
The Lilac Tactile Switch has Nylon bottom housing and is marketed as "smoother than T1", comparing it to T1 switches with PC housing. It has black housings with lilac (whitish purple) slider.
The Durock switches are manufactured by JWK. The relationship between Durock and JWK is unclear, as JWK also manufacture other tactile and linear switches that are similar to Durock T1 and Durock Linear respectively.
The Everglide Oreo and Everglide Crystal Purple which are also manufactured by JWK are allegedly identical to T1, but that has not been confirmed.
The original has Tacit a clear housing and a "wasabi"-coloured stem. It has also been sold as Bushi, Kakktus and Kakko with different colours.
Keebwerk is believed to have an exclusivity agreement with JWK for the damped tactile variant.
