A system which in some embodiments comprises a wireless smart device assembly that includes a smart device, wherein the smart device assembly is attachable or mountable against an unopened surface of a wall or other structure. In some embodiments, a system comprises a smart device assembly that includes a smart device; and a fastener that includes adhesive and is coupled to the smart device assembly and releasably attachable to a wall or other structure. Some embodiments include a level indicator configured to indicate the angular position or orientation of one or more other portion of the smart device assembly relative to parallel and/or plumb to the force of gravity. In some embodiments, a mount and/or a cover define a catch to releasably attach the cover to the mount.

An electromagnetic relay includes a fixed contact module including a fixed contact, a movable contact module including a movable contact disposed to face the fixed contact, an armature formed of a magnetic material and configured to move the movable contact module to bring the movable contact into and out of contact with the fixed contact, and an electromagnet configured to generate a magnetic field to move the armature. At least one of the fixed contact module and the movable contact module includes a joint at which different components are joined by riveting, and a film with a thermal conductivity higher than, the thermal conductivity of the fixed contact module and the movable contact module is formed on at least one of the fixed contact module and the movable contact module including the joint.
