[ROVERNET - UK] Worn ignition switch 70 3500S

[geffandjulie]

My ignition switch is so worn that it does not remain in the on position 
after starting. Only by jiggling and praying does the key remain turned 
enough to allow current to the ignition. Fortunately I have a NOS switch to 
replace. 3 Q:
If it fails before I have time, can I "jump" any wires to keep it going?  Is 
there a quick fix to the wear?  How difficult is it to replace the assembly?
