If you don't mind the aesthetic views of it, you could try replacing it with a simple rotary switch.

perhaps the O P needs a movement not rotary switch.

Generally the helical spring burns off, if used in wrong range. May be, it is better to call it  dead , than further investing on it , and may be , if the O P likes, he may switch over to some auto ranging type 3.5 digit DMMs instead.
