The first opening is aligned with the second opening and exposes a part of the rear surface of the circuit board. The adhesive layer has an annular zone adjacent to and surrounding the first opening. The annular zone directly contacts the circuit board. The waterproof button module further includes an electric-connection assembly and a switch. The electric-connection assembly is electrically connected to the circuit board, and passes through the first opening and the second opening. The switch is electrically connected to the circuit board, and has a button. In addition, an electronic device including the waterproof button module is disclosed.

An adapter is for a metering assembly. The metering assembly includes an electrical switching apparatus and a socket assembly. The socket assembly has a plurality of jaw members. The adapter includes a base member and a plurality of electrical contacts each coupled to the base member and structured to be mechanically coupled and electrically connected to a corresponding one of the jaw members. Each of the electrical contacts is structured to be electrically connected to the electrical switching apparatus.

An improved mechanical interlock including one or more features to facilitate a more robust design, easier assembly, and/or enhanced capabilities. For example, the mechanical interlock may include an interlock latch operatively associated with an external handle assembly and an internal connector. The interlock latch being directly coupled to a shaft coupled to the handle assembly, thus providing an improved and more robust latching mechanism. The mechanical interlock may also include one or more keys (e.g., a Poke-Yoke feature) to facilitate easier assembly and/or to prevent human errors caused by improper assembly. The mechanical interlock may also include an integrated magnetic switch and monitoring system to ensure that accurate location of the handle assembly is known.

A button structure and a terminal using the same are provided. The button structure includes a connecting element, a press element, and at least one elastic element connected to the connecting element and the press element. The elastic element is configured to provide a restoring force after the press element is pressed toward the connecting element. The connecting element is provided with an instruction transmission port and at least one of a current transmission port and a data transmission port. The press element is provided with an instruction triggering port and at least one of a current transmission pin and a data transmission pin. The current transmission pin is electrically connected to the current transmission port to output or input current. The data transmission pin is electrically connected to the data transmission port to output or input data.

A power-circuit breaking device includes a receptacle and a plug. The receptacle includes a power terminal and a signal terminal. The plug includes a main terminal and a sub-terminal. The plug includes a plug housing, a lever which is attached to the plug housing, a lock slider which is attached to the plug housing, and a sub-connector which is supported by the lock slider. The plug housing holds the main terminal. The sub-connector holds the sub-terminal. When the lock slider slides, the sub-connector moves. When the lever is located at a closed position, the main terminal is connected to the power terminal. When the lock slider is located at a connected position, the sub-terminal is connected to the signal terminal.

An embodiment of a fuse module has been disclosed. The fuse module includes a housing, a fuse element unit disposed within the housing, and a pair of terminal blades between which the fuse element unit is electrically connected. Each terminal blade has a pair of connection portions.

A multiple relay arrangement having a plurality of relay sockets which are arranged next to each other and a plurality of relays. The relay sockets contain additional plug connections with which the relays are controlled by the system cabling. The system cabling contains a distribution section having cable sections and plug connectors and allows the plurality of relays to be controlled.

An overvoltage protection device comprises at least one overvoltage protection unit having at least one contact lug as well as a mechanical disconnection apparatus that is activated in the event of a thermal overload. The mechanical disconnection apparatus comprises a connection element that can be moved from a closed position to a current-interrupting or voltage-disconnecting position by a slider that is preloaded by spring force.
