Depending on the circuit type, the 5K Ohm CT2226-ND that Michael linked to has a pretty decent chance of working.
If the pot is being used as a voltage divider (all three contacts used; one end V+, center variable voltage output, other end Ground) then the actual resistance value often isn’t critical. Usually such configurations are used to present a variable voltage to the next stage of the circuit, and typically source little, if any, current.
If it is being used as a rheostat (only two of the three contacts) then there are a few more issues to consider. First is that we do not know the power rating of the original pot. The CT2226-ND is rated for 1/4W, so if the original MLC pot was rated for a higher power, that could pose a problem if the circuit dissipated more than 1/4W. Second is that because the CT2226-ND is a 5K part rather than a 2.2K part, it would have a smaller usable range (less than half the rotational range used), making it more difficult to hit a desired set-point. It’s not likely to harm anything with a higher value resistance, but impossible to know for sure without seeing the schematic of the circuit.
The switch is rated for 3A @ 125Vac, which exceeds the rating of the original, so that part of it should work, at least.
