Mag switches can be a PITA on the wrong machinery... I replaced my DP with a light toggle

so I can operate it with a foot switch,

... though even after a few vinos I can hear the DP come back on and keep my distance... however, the built in mag-switches have their place in your shop.
I will never poo-poo a mag switch on serious powered machinery, but dusties are on their own.

I still use remotes on "other" viscious machinery, but there is another intermediary controller in between. that needs to be activated after a power outage... but then stays permanently on.  
till the next knife in the power point.
I'm no sparkie, but if I manage to post another puzzle tomorrow, I may be doing the right thing.,. costs a few shekels more, but contrary to SWMBO's costings, I'm hoping to be worth a tad more than $0.05... $0.10 in my sexy nightie. 

If your first cut is too short... Take the second cut from the longer end... LBD
