'''USw LMBW02''' is an extremely rare switch from an unknown manufacturer. '''USw LMWW01''' is a heavier weight version intended for a space bar.

==Manufacturer==
According to Tai-Hao, the manufacturer was a now-defunct Japanese company whose name may be "Katano".<ref name="TH-20170308" /> No other details about the switch have survived.

==Description==
The contact arrangement is a hybrid between a full [[switchplate]] and bare contacts: the actuator leaf and movable contact are the same part (where a "true" switchplate has a separate actuator leaf that engages a prong that presses on the contacts), but the contacts are held together by a plastic moulding.

A second pair of holes in the base permits an LED to be fitted to the switch; the LED is located to the corner of the switch.

This switch is only known from a single keyboard, Tai-Hao TH-5150. Here, it is paired with [[Tai-Hao TH series]] keycaps, which appear to be[[Cherry MX mount]].

==Keyboards==
*[[Tai-Hao TH-5150]] (1987)

The example below is from Tai-Hao's own preserved TH-5150. The shell design is distinctly different.
