I built this enclosure that has a pneumatically driven positive purge system. This purge system has a 24vDC switch that closes when my enclosure has a purge. I want to connect this switch to the incoming AC power. If I lose purge I want all my electronics turn off and vice versa. I was thinking I need a relay, but I am not sure what could do this. Thanks for all your help.

Something like this can handle up to 30 amps at 277 VAC. Be careful and remember to fuse or have a circuit breaker in place. What is the total current (sum/draw) of the electronics you want to turn on?
Also, what is the current capability of the 24 volt DC supply (and is anything else connected to it)?
Would you be expecting any 'interruption' of the purge, IE specifically, something that might provide a glitch where the relay might suddenly turn off and back on (not good for your electronics)?
All of the above scenarios can be accomplished with specific circuitry.
Advise if further assistance is needed.
