Pressure activated switch
Posted: Sat Aug 15, 2009 1:37 am
A long time ago I recall seeing a pressure activated switch being sold by one of the spud gun stores... possibly BC Arms.
The switch was a small, simple unit with a 1/8" NPT male thread which would connect to the pressure vessel. On the opposite end were two contacts. When the pressure reached a certain point, (IIRC 125psi) the circuit would close.
I've found various sorts of pressure switches but none as compact and simple as this one was. I'm very inexperienced with electronics so if anyone could point me toward something similar to what I saw it would be much appreciated.
I hope to incorporate this switch into a device that is part of an ROV project I'm working on.
Thanks!
