Airlock Doors

A door assembly (ideal for an airlock) with wiring that prevents both doors from being open simultaneously while still allowing both to be closed simultaneously. Both doors open and close as expected until one door is open and then you attempt to open the other door.

For example, If the left door is open, pressing the button for the right door will simultaneously close the left door and open the right door (or vice versa).

The assembly uses two windowed doors, but you can change those to whatever kind of door or hatch you want to use. Because the design uses a circuit box, you can easily change either of the doors simply by wiring the state_out and toggle_state to the contacts on the circuit box.
