When button is released, saw stops.

Have a switch for a table saw that worked when saw was set for 220v. Now saw has been rewired for 110 and saw only works when on button is pressed in. When on button is released, saw stops? Is there something that has to be done to re-set one of these switches or is there another problem? Switch is a KJD17B.
Thanks

The switch has an electromagnet inside. Did you change to a 120 volt switch? A 240 may not hold at 120 volts.

Exactly what connects the motor conductors to the "Line" conductors ?

The switch is for 220V. That may be the problem. I may need to have a switch that is rated for 120v. Thought that if the switch I was using was rated for 240v, then it should be OK for 120v.

The switch acts as a safety device so the saw doesn't restart automatically if power is lost. The electromagnet is probably set for a certain voltage threshold. Heavy duty power pushbutton switch | power rated push button | industrial power pushbutton

Ray is correct. The correct switch must be used based on the voltage. 120v won't hold the 240v magnetic coil in.
