Validation systems and methods are described to validate domain name services or other configuration data for multiple network services provided by a common multi-tenant application server. The MEMS switch includes first and second spaced apart electrical contacts, and an actuating electrode. The field pulse is sequentially applied to groups of the sense layers of the Wheatstone bridge structures, thereby allowing for a higher current pulse or larger sensor array size for maximal signal to noise ratio. The enclosure also includes a cable having first and second opposed ends, and the base includes at least one cavity supported by the base and configured to receive at least one of the first and second opposed ends of the cable. The first layer index n2 causes light input through the back surface of the layer to be preferentially output into the first layer.
