A table comprising a table base and a tabletop is disclosed. The table base comprises a top surface comprising a rotatable portion comprising one or more permanent magnets. The rotatable portion rotates independently from the table base. At least a portion of the tabletop comprises a ferromagnetic material.

Rotation of the rotatable portion of the top surface, such that the one or more permanent magnets are oriented away from the ferromagnetic material, engages or disengages the attractive force.
Optically transmissive key assemblies for display-capable keyboards, keypads, or other user input devices
A key that includes a body with an optically transmissive or light permeable region and an optical film coupled to or carried by the light permeable region is disclosed. The key also includes a resilient structure coupled to the body. The key can be assembled or coupled to, or disposed relative or adjacent to, a display screen. The key also includes a switch actuator (e.g., an electromechanical switch actuator or contact element). Displacement of the key, more specifically the body of the key, displaces the switch actuator for actuating a switch. The resilient structure is configured to bias the body at a first position. The body can be actuated or displaced from the first position to a second position for effectuating corresponding displacement of the switch actuator and actuation of the switch. The resilient structure provides a positive tactile feedback upon user-directed or user-controlled actuation or displacement of the body.
