A sensor is configured to receive an input associated with a human present in a physical space in which a device is deployed. A physical circuit path is configured to electrically couple an output signal generated by the sensor to a premises automation system processing component. A physical privacy switch is configured to have a first position and a second position, wherein the physical privacy switch connects the physical circuit path when in the first position and interrupts the physical circuit path when in the second position.

A locking system for a temperature-controlled container is provided. The container has an interior and a barrier having an open position allowing access to the interior of the container and a closed position blocking access to the interior of the container. The locking system includes a temperature sensor for sensing a temperature within the container; a locking device coupled to the barrier to lock the barrier in the closed position; and a controller in communication with the locking device and the temperature sensor. The controller receives the sensed temperature from the temperature sensor and controls the locking device based on the sensed temperature. The controller is configured to control the locking device to lock the barrier in the closed position when the sensed temperature rises above a predetermined threshold temperature.

An electrical switch with a conductive bridge, a first wire configured to provide continuity with the conductive bridge, and a biasing member connected to the first wire. The biasing member provides a threshold reaction force to maintain continuity between the first wire and the conductive bridge. The switch further includes a housing that directs tensile forces acting upon the first wire to oppose a reaction force of the biasing member. When a tensile force acting on the first wire exceeds a threshold reaction force of the biasing member continuity between the first wire and the conductive bridge is broken.

A knife holder for holding a knife includes a block defining a cavity to receive the knife, and a casing removably arranged inside the cavity and adapted to be locked with the block. The knife is removably arranged inside the casing. A lock structure locks the casing with the block to prevent the removal of the casing from the cavity. Moreover, a switch is adapted to be actuated by a user to enable an unlocking of the casing from the block to enable a removal of the casing from the block. A near field communication device is configured to determine a presence of an authorized user in a vicinity of the knife holder and facilitates an unlocking of the casing from the block in response to an actuation of the switch in the presence of the authorized user in the vicinity of the knife holder.

An apparatus for controlling current in a circuit may include a motor, a leadscrew coupled to the motor, and an actuator arm coupled to the leadscrew. The apparatus may include a common terminal, a normally open terminal, a normally closed terminal, and a contact arm configured to couple the common terminal to the normally closed terminal in a first position and to the normally open terminal in a second position. A spring can bias the contact arm toward the first position, and the motor can be configured to operate the leadscrew to move the actuator arm, and the actuator arm can be configured to move the contact arm from the first position to the second position.
