It seems that it can only be used at the weakest capacity by using the interlocking outlet of the dust collector, so I bought it here. I think that there is a click feeling moderately and it is easy to step on.
Though I used about 20 years ago, I used to replace it because it started to cause malfunction of the contacts recently. It is the same aircraft as the one attached earlier. There are various FSWs of the same contents, but since the pitch of the installation position is different, I bought the same thing. Because it is thin, it is not very disturbing and usability is good.
