Some of you have seen that I made my own blast gates and switches to
turn on my vac system.
Well, a couple have given me problems occasionaly. I thought it was the
brass not touching the rub strip due to being bent. That turned out not
to be the case. It was sawdust blocking the bar...
Today I replaced one with a magnetic switch (reed switch) normally used
for home security systems...
I didn't want a micro switch as it might be finicky getting it right.
The magnetic switches NO are perfect. I had 2 one NO Normally open, and
one NC Normally closed. I used the NO..
The nice thing is that the magnet just has to get close and it turns on.
so it's on... not worried about topping out.
So just thought I would give you a heads up. I might do one for the DC too.
