BackHex Complementary D Rotary switch, 4-bit encoding, 10 positions, Complementary code K rotary hex Gray D 1x DIP Switch, Single Pole Single Throw (SPST) switch, small symbol D 11x DIP Switch, Single Pole Single Throw (SPST) switch D reed switch, default-closed D SPDT reed switch K reed magnetic switch SPDT D rotary switch - this needs measuring, and leaving space for a few mm taller than a DPDT toggle. In that case the pots and the MCP4922 DAC (others may work).
