i am still in the design phase of my breeding rack for my leos and saw the wiring article here at herpcenter. i noticed that you could jump from tape to tape on different levels. is it possible to put in a switch between the levels also? id like to make a decent sized rack but i realize i may or may not need all of the levels at the same time. could i install a swith so i could turn one or more of the levels off when not needed?
