I have made an "invasion" mode switch in my base that actuates blocks to allow mobs to fall into a death hole so they cannot access my base from the asphalt highway, i need to know how i can make a switch that has two outputs, when i click it once one output emits a signal and when i click it again the other output emits a signal, so i can connect it to two Announcement boxes that display message "invasion mode enabled" and "invasion mode disabled" how can i make such a switch?
