You could theoretically do it without any circuit diagrams by using an (on)-off-(on) SPDT switch and wiring both (on)'s together. Then you could label one direction 'open' the other 'close', even though either way would both open and close the drive tray.
BTW: in switch nomenclature anything in ()'s is a momentary connection.
