An arrangement includes a switch including a plurality of connectable modules. A first module is a connection module, electrical connections running into an interior, starting from the connection module for connection purposes. A second module is a manual plug module, connectable via its second contacts to the connection module, electrical connections passing external to the switch starting from the manual plug module for connection purposes. A third module is a communication module including a communication electronics system and including second contacts and first contacts, the communication module being connectable via its second contacts to the connection module and the manual plug module being connectable via its second contacts to the communication module. Second contacts of the communication module are electrically connectable to first contacts of the communication module or to the communication electronics system. The communication module is a communication adapter and the communication electronics system is connectable thereto.

A sealed electrical enclosure for housing an electrical component is provided. In one exemplary embodiment, the sealed electrical enclosure includes a housing, a first and second electrical connector, an actuator, and a terminal. The housing has a sealed interior when a top portion is coupled to a bottom portion. The first electrical connector extends from the sealed interior through the bottom of the housing and is electrically coupled to the electrical component. The actuator extends from the sealed interior through the housing and is configured to manipulate the electrical component. The terminal is electrically coupled to the second electrical connector. The second electrical connector is configured to mate with the first electrical connector. The first and second electrical connectors are configured to be connected and disconnected to attach and remove the housing to and from the terminal.
