I have a LeeValley veritas steel top that a router clamps to. Doesn't look the same as that but I've never had it loosen off. I use an on/off remote foot switch with it. I put it where I have to reach for it so I don't step on it accidentally. Some have opted to install a household type light switch close by. The perfectionists have opted for the proper magnetic switch which only requires a bump to shut off power. It's still a good idea to unplug it when making bit changes.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
