thermostat to wall ac project

i need help with designing a circuit so that i can make my nest thermostat turn on a wall AC unit

the nest requires 24v ac to allow the tstat to open/close the contact

the wall AC requires a momentary close of the power switch

 

so i need help making a relay momentarily close when the nest contacts close and again when the contacts open

 

is this clear? can someone help me?
