I bought a Bernina 910 a couple of years ago and the cord was wired to a Kenmore foot control. The original Bernina controller had broken and the seller just said "this is a generic foot control replacement". Of course, I recognized the FC as one just like my 158-series Kenmore! so she admitted it came from the thrift store and I negotiated a lower price to compensate. In my case, you have to have the right FC to have the needle tap up-down feature and I was able to find a Bernina FC for about $75. But otherwise, the Kenmore FC operated the machine, just not smoothly , and not correctly. I could tell the difference, but yours may work just fine.
