Just want to make sure this is the correct schematic for what I am doing.

I am installing a dehumidistat in the bathroom for the exhaust fan along with a switch. I want either/or to be able to turn it on.

i.e. Turn on the fan with the switch when you first get into the bathroom before you start taking a shower. You turn on the shower and the dehumidstat closes its part of the circuit. I'm done with the shower and I turn off the switch, but the fan is still running because the dehumidstat is still closed. Eventually the fan will turn off once the humidity level has gone down. I basically just want them to run independant of each other and not interfere with each other. Is this diagram correct?
