An optical switch for alternatively redirecting a source beam includes a director assembly that is selectively moveable between a first switch position, a second switch position, and a dual switch position. The methods can provide multilayers capable of satisfactory power generation properties as an electrode structure by forming an electrolyte membrane on an electrode without causing any penetration of electrolyte into the electrode. The base has support members extending in transverse relation to and outwardly fore and aft from the outer perimeter frame and adapted to rest on a generally level support surface such that the outer perimeter frame extends upright from the base enabling the doorway structure to assume a free-standing, self-supporting orientation on the support surface.
