Normally Closed Transistor Help

[Tesla]

Hi all,

I need help with a circuit that gives me a 5v (high) when a normally closed circuit is opened.  How do I configure the transistor and is it PNP or NPN.

Thanks,
Jason

I have thought about it.. if I use a PNP and keep base high and then when open base is low, the current will flow E to C... correct?

what is the transistor connected to?
you could use a no relay so when the circuit opens it closes the switch?

In PNP it's Collector high rail, Emitter device
In NPN it's Emitter low rail, Collector device...

Thanks guys.. I figured it out!
