Finished a small project today.
Some people have tried to use a $10 remote switch to control their DC.
They found that the ratings were insufficient to run the DC and it burned up the switch. I think someone was able to fix that by soldering some new traces on the PCB of the switch, but it really is over the ratings of those switches.
Others bought the $80 remote from Grizzly.
I decided to resolve mine differently. This will also work for those Sears Slave switches used to turn on a Shop Vac, when the Power tool goes on. but you want to operate the shop vac from a separate AC circuit so as to give all 15Amps to the Table saw.
The heart of the device is a $6 relay or contactor I bought on the internet. It will switch 40A resistive or 30Amps motor current and has a 120V coil that takes just 5 watts to pull in the relay. You can control the relay with the remote switch or the slave switch.
Anyone interested, want to see the circuits or relay source?
Edit: Instructions/circuits are now posted here:
