Subject:Off topic Friday question on switches...
From:Don Hanson
Date:Fri, 16 May 2014 07:59:29 -0700

I have an induction-motored thickness planer, running on 220 single phase
power...It came with a magnetic switch that has broken now 3 times and
costs over $50 to replace...Hate that.   I found a normal power tool switch
in my box, rated for a bigger motor than this tool I am working on
now...but it is a "normal" heavy duty push button power tool switch, made
for 120/230 single phase or 208/230/480 three phase...   This switch has
four terminals on the back, two labeled "Load" and two labeled "Line"...

   So the questions:

  Can I try to wire up this less expensive (and already owned) switch to
make the 220 induction motor work?  Right now I am using this tool, when I
have to,  with my power panel breaker box as the only switch....very
un-safe and not at all convenient.   I do need the use of this tool, but
$50 a switch is now (in this tradesmen-unfriendly economic climate) not
very feasible.

  Second question:  If I decide to try this hack-job, wiring  for the wrong
switch,  how should I connect the wires?   Do I take the black and white
wires to the two terminals labeled "LIne" and continue on after the switch
with the same colors out to the tool from the "Load" posts of the switch?
Or do I just break one of the "Line" wires and use just one of the 'Line
and Load" terminals, like on a house wiring switch?

   I know this is sketchy stuff but it's really tough for a working man in
the building trades now a days so I can't afford to do it right always when
it comes to my own tools and expenses..I tried Goggling "induction motor
wiring" etc etc...but I can't understand the wiring diagrams I get back...

  Respond off the list if you think you may be able to advise, and thanks
