N.O.S. Relay

[Phil Rickard]

<<Did you use one of the ganged relays?.>>

The one I used was the RBSN-TTL relay that could be triggered by either a
ground or voltage path and then connected the output side of it to a common
terminal that the N2o and fuel solonoid grounded to. The rest of the circuit
did consist of seriesed relays that relied on one another to make a complete
circuit for the other, with the WOT and rpm switch being the master.

<<What for pressure switches did you use?.>>

I used to build racing transmissions in a past life and I had a supplier
that sold high pressure switches used for fluid pressure sensing and they
had just about any type or pressure sensor increment you could think of.
They sort of resemble the low oil pressure switches that are commonly found
in automotive use....you know, the ones you can buy from NAPA etc. The major
difference is that they do not incorporate plastic in their
construction.....probably due to the possible high pressure they may see I
guess. I don't have that suppliers name here in front of me at the
moment....(I had to beg my old boss to give me the vendors name in the first
place), but if memory serves the company is called Aurora Fluid Power.
