Abstract : A remote fluidic controlled electric switch adaptation is disclosed. The adaptation is electromagnetically transparent and material costs are near zero. An electric switch, containing mechanically operated contacts, is modified by a flexible diaphragm secured next to the switch's mechanical contacts via uses an electromagnetically transparent housing. Pressurized fluid, either liquid or gas, enters the housing and inflates the diaphragm. This exerts positive pressure on the electric switch's mechanical contact and causes the electrical contacts to close, turning the switch on. Releasing applied fluidic pressure allows the diaphragm to relax, causing the switch to turn off. Adaptation materials are electromagnetically transparent for use in electromagnetic experimentation and cost less than 1 percent of the cost of the electrical switch to which the adaptation is applied.
