I have not seen that particular switch and it is very different than the one on my 47 which is like the one shown in the 645-E booklet -- only wires connected. Can't see enough detail in the photo to tell what might be on the other side of the bracket and how many and where all wires connect. I am wondering if the item on the switch could be a combination breaker and resistor as is mentioned in one of the descriptions of operation. If that is the case, then with just the external switch like we have a similar item should be on the motor assy too. You need to confirm exactly what is on the switch. If any of the resistor components are on the motor assy and might still be connected when the old breaker is bypassed and that new switch is substituted, there will probably be some issues.

I found this actual wiring diagram on one of the early patents. At a quick glance it appears to be what I have . 186 is the breaker, 188 is the low speed resistor and if another resistor still active on the motor assy is placed in series the resistance is doubled so motor will have issues and might not move, if placed in parallel the resistance will be about half so less than needed and there will be very little speed change or maybe two higher speeds instead of a high and low speed..
