ME!

I've used these oil pressure switches on several bikes over the years.  A great idea to use them.

A word of caution, the smaller ones use one of three different sizes of thread.

1/8" BSP 28TPI,    1/8" NPT 27 TPI,  M10 x 1 25.4 TPI.

Visually they look to be the same, measuring the outside diameter might not be conclusive in separating the imperial from the metric.  Check with a thread gauge.   The heavy handed will get the BSP and NPT to screw together.......... 

Don Pender also sells a take off electrical sensor ( from timing cover outlet to rockers ) which triggers an indicator light for low pressure warning. $30.
