A first electrode and a doped oxide layer laterally proximate thereof are provided over a substrate. A configurable button may have a button member that moves relative to a device housing when it is desired to activate a switch. A releasable fastener-locking mechanism is attached to the primary shaft and a tightening member movably mounted to the primary shaft. The first annulus and the second annulus are configured to communicate with each other proximate to the distal end of the housing.
