Seems like more work than my proposal. If Platform A is initially active, adjacent to Platform B, and is set to activate adjacent platforms upon deactivating, then a Tag should work right. If not, you could use a whole bunch of similar platforms with all the lights you need set to deactivate when their respective platform deactivates, and have the switch simply be a platform switch.
