Speaking of switches...
Since I reside in an area which does have power failures from momentary to extended, I installed a Grizzly Industrial magnetic starter on my router table.
Once had a brief power failure -- off & on very quickly --good thing I had a firm grip on the work. Even though my Unisaw, the 15" planner, & 8" jointer have magnetic starters, I never gave the router any thought. That is until then when the ol' PC7518 seemed to come on all by itself. Good thing I have strong bladder & sphincter control & firm grip on the work....
W/ a magnetic starter, once the power fails, you must push the on button to restart the electrical flow to the tool. Do a Grizzly search for "switches"
I believe this is the unit I purchased: is Magnetic-Switch-Single-Phase-110V-Only-3-HP, item #G8292
Lee Valley offers a short 3 receptacle extension cord that also requires a manual re-set after a power interruption, Portable GFCI cord, # 03K51.10
As the remote controlled cyclone DC is hooked up to the router table, I don't need to worry 'bout starting it the same time I do the router. In fact, I like to start the cyclone & the shop vacuum before the tool & run it a brief period after shutting down the tool. That way the DC/vacuum clears the hose of all the debris. If you have ever shut off the shop vacuum & have sawdust, etc., drop from the hose, you know what I mean.
