I have a Rockwell unisaw from either 1969-70. The motor is a 3 hp baldor single phase 220 V and the motor says 32 amps. The magnetic switch stopped working and the saw will only run if I physically hold/push the switch button in. I disassembled the switch, blew it out with air. The switch does not have the overload protection or a reset button like the newer ones. I was going to buy a new switch but there are 4 wires running to the switch. All the new switches I have seen only have room for 3 wires. I did notice that the new 3 phase switch have 4 wires running to the switch. I have attached a couple of pict of the box on the back of the machine. If you look close next the red wire there is a red plastic tab with grey overspray on the tip. I thought it was a reset switch but it does not move. Does anyone have a solution to this? Thanks in advance! Jack
