The light switch on my 1980 R80/7 was stuck in the on position. Went the local Autozone with
switch in hand and found a substitution. RB401 Duralast Stoplight Switch $18.99. It is a little longer and has a
tapered threaded end. No brass washer needed. Just some teflon tape on the threads and tighten down.

This appears to be something that fits water cooled VWs. The IBMWR site lists the item although not by part number. Your part number fits many VWs per the Autozone website:
