An optical relay is disclosed in which a liquid metal droplet is moved within a switching channel formed in relay housing. The desired feature in one embodiment may be a backside trench. A received SDID causes a single database read to access all other SDIDs, and any existing UDID associated with the client device. The spring-loaded lever only engages the switch when the mounting plate, ultra-violet lamp, and base are properly configured. The member has at least one surface which is coupled to the first main surface.
