I need a new oil pressure switch for my 1964 Super Dexta. Part number E1ADDN9278. Would a switch from a Ferguson with a Perkins engine fit and work properly? That might be more easily located in the U.S.
Thanks, Terry
I may have a problem. Should the threads be 1/2'' diameter?

Not sure about the Ferguson switch, however your old one is a 1/4 BSP thread (BSP is measured on the internal pipe diameter) which has an over all thread diameter of 0.518" so yes yours is correct.
Correct me if I'm wrong but older dextas (1957-58 ) used a 1/8 BSP oil pressure switch.
I suppose any 1/4 BSP switch will do

eddiej is correct , ford as with alot of the dexta parts was always making changes, through out the run of dexta/superdexta,trying to save money i supose
,the oil switch is one example the thermostate housing was another which threw me for a time, but there are two sizes the early and later switches, 1/8 an1/4 ,
