66-16 foot and knee controller question
I have acquired 1928 Singer 66-16 in a No. 40 cabinet, that has a knee controller hardwired to the backside of the 3-terminal plug socket. Can I add a 2-wire foot controller (and keep the knee controller functional) simply by plugging it into the plug socket in lieu of the original power cord? My limited logic says that I should then be able to use either controller as I choose.
Thanks.
