[Shop-talk] Remote power switch

[Jeff Scarbrough]

A bit more fiddly, but look at how a central vacuum system works.  Every
place you have to plug in a hose, there are  a pair of metal pins.  Push
the hose in, and the metal sleeve connects the pins and energizes a relay
that starts the vacuum.

A relay or motor starter for the vacuum and a handy switch near each tool
would let you turn it on as you turn on each tool.  Yes, you have to flip a
switch, but you don't have to leave the tool to do it.  And I bet it's a
whole lot cheaper than a lot of these other systems.
