Indeed the part number cast into a part is rarely the actual volvo part number

These switches go right back to the last 140 models at the end of 1973 and are extremely robust as they switch the high current loads of everything .

The 850 gave some trouble but that was with the linkage to it rather than the contacts resulting in the switch not being fully latched in the right place on the contacts . They rarely gave trouble under 100,000 miles though .

Later when relays started taking the loads from about 2000 they had plastic casings of the same design and plug fitting and presumably lighter contacts inside ,but still extremely reliable .
