Provided by the present invention is a refrigerator door body, having a door lining and a storage device installed on the door lining. A hanging lug and a matching groove that match each other are provided between the door lining and the storage device, wherein a power supply module for supplying power to the storage device is provided between the hanging lug and the matching groove. The refrigerator door body also has a switch mechanism that controls the power supply module to turn on and off. The switch mechanism is configured to: turn on the power supply module for power supply when the storage device is installed on the door lining, and turn off the power supply module when the storage device is separated from a door lining installation position. The refrigerator door body of the present invention improves the safety of a user during use.

A method for charging an auxiliary voltage source that provides power for at least one additional component, the additional component being in addition to an electric drive that is powered by a main voltage, is described. The method includes electrically connecting a protection and/or control circuit to the main voltage source via a DC-to-DC converter configured for power supply, and to the auxiliary voltage source via a reverse blocking valve. The method further includes electrically connecting the main voltage source to the auxiliary voltage source via a charging device. The method still further includes charging the auxiliary voltage source via the main voltage source.

A method for charging an auxiliary voltage source of a boat having an electric drive that is powered by a main voltage source of the boat, the auxiliary voltage source providing power for at least one additional component, is described. A protection and/or control circuit is electrically connected to the main voltage source via a DC-to-DC converter configured for power supply, and to the auxiliary voltage source via a switch or a reverse blocking valve. The auxiliary voltage source is charged via the main voltage source.

The present invention provides a magnet, which comprises a body having a first and a second section, and a slide arranged to be movable relative to the body between a first and a second position. The slide comprises a permanent magnet, and a first and a second pole piece that are attached to opposite magnetic pole surfaces of the permanent magnet. The first section comprises a hole that opens into a first cavity of the body, the bottom of the first cavity being delimited at least partly by the second section. The slide is movably arranged in the hole so that the second pole piece is directed towards the bottom of the first cavity, wherein at the first position of the slide, magnetic flux generated by the permanent magnet is short-circuited by the first section, and at the second position of the slide, magnetic flux generated by the permanent magnet is directed through the first and the second section.

A switch that includes a hermetically sealed container including a container wall separating an inside of the hermetically sealed container from an outside of the hermetically sealed container, a magnetic sensor arranged in the hermetically sealed container and configured to be turned ON/OFF by a magnetic field of a magnet acting from the outside of the hermetically sealed container through the container wall of the hermetically sealed container, and a first magnetic body provided at the container wall of the hermetically sealed container and serving as a path of the magnetic field acting on the magnetic sensor from the magnet.

Disclosed embodiments relate to an auxiliary relay of an electronic contactor. In some embodiments, an auxiliary relay has its conducting state controlled by a plurality of lead switches, in a non-exposed state of contact parts to the outside. This may prevent dust or foreign materials from clinging to the contact parts.

A calibration system having an actuator with a rotatable shaft and a switch box housing a proximity switch and a calibration mechanism. The calibration mechanism is coupled to the shaft and includes a base, a target carrier, a driver, and an actuating button having a cam. The base includes a locating magnet, and the target carrier includes a primary magnet and a bias magnet polarized in the same direction as the locating magnet. The driver is shiftable between a first position in which the driver engages the target carrier and a second position disengaged from the target carrier. The cam engages the driver and shifts the driver between the first and second positions. Upon rotation of the shaft, the bias magnet automatically moves to a position aligned with the locating magnet when the driver is in the second position.

Electronic switching device having a housing in which at least one printed circuit board with circuit parts is arranged, the housing being designed with at least one housing cover, which closes a housing opening, and with a cable bushing for a connection cable and being provided with a filling made of a plastic material which surrounds the printed circuit board with circuit parts, wherein the printed circuit board (2) is encapsulated in the housing (1) in a supported manner on a grid-like carrier body (6), to which end the grid-like carrier body (6) has individual supports (7) which span an adjustment plane (X) depending on heights (Y) of the supports (7) and on which the printed circuit board (2) can be fixed at a distance from the housing walls (8, 9, 10) for a localized arrangement of the encapsulated circuit parts in the housing (1).

A transportable container assembly including a transportable container defining an enclosed interior space and having an opening member cooperatively engaging a mounting frame. The opening member has a closed position and an open position and access to the interior space is permitted in the open position. A localized device or system is attached to the transportable container and is coupled to an electrical power source. A reed switch apparatus coupled to the transportable container communicates the position of the opening member to the localized device or system. The localized device or system provides a localized function depending on the reported position of the opening member. The localized function includes at least one of a group consisting of a local lighting function, local locking mechanism action and local refrigeration system action/function. The localized device or system communicates the position of the opening member to a remote device or system at a location remote from the transportable container. The remote device or system is capable of providing remote monitoring and control functions or actions at the transportable container depending on the communicated position of the opening member.
