I'm not sure anybody ever made anything like this. Aside from the "MBF" which has not been legal to sell in the UK since 1763, the 5 amps is a killer. Industrial supply houses carry 3 position "reversing" switches with a rotary action, suitable for 5 amps @ 460 VAC, but they are on-off-on. Probably your best bet would be to combine a regular 6 position rotary switch with 6 relays or, if truly dc@50V, 12 transistors. You'd need a little wall plug power supply for the relay coils or the transistor base feed. If ever much below 10V, silver relay contacts would be better than copper.

Thanks they do seem to be tricky to get, althought mouser does have this R20507RR02Q C&K Components Rotary Switches.
Relays are too much of an effort and space. Transistors will introduce resistance in the current path and an unnecessary voltage drop.
All I want is a switch to select an appropriate value current sensing resistors. The highest current is 5A (or 6A maybe) so I was looking in general for a 5A capable switch.
The thread discussing this is in power supplies where I will continue.
