Believe my Delta drill press is around a 1943 Model. The push /pull switch w/ rod has been acting up. The switch is mounted on the side of the motor and the push/pull rod goes forward. I've found some scattered info on Pinterest re rewiring and or replacing with a much newer switch. I'd like to maintain the vintage style if possible. There are 4 wires exiting from the motor case. Don't know quite where to start ? I did find a replacement (looking) switch base on ebay, but 'am skeptical.
Ideas??
Thks,
