Abstract: An electrical equipment (1) for an electrical installation is connected to an electrical grid, having at least a primary functional module (2) suitable for carrying out a current interruption function, and an additional functional module (5) for carrying out at least one function requiring a power supply. The function of the additional functional module (5) is a function requiring a power supply except for an indicator light lighting function.

Abstract: An electrical equipment (1) for an electrical installation suitable is provided, connected to an electrical grid having at least: —a primary functional module (2) suitable and intended for carrying out a current interruption function, and an additional functional module (5) for carrying out at least one function requiring a power supply The function of the additional functional module (5) is selected, alone or in combination, from a function of measuring at least one physical parameter and/or a function of emitting and/or receiving electromagnetic radiation, and/or a display function, and/or an actuation function, and/or a data processing function, and/or a function of converting a physical signal into an electrical signal or vice versa.

Abstract: An electrical unit (1) for an electrical installation that is connected to an electrical network, comprising at least: a primary functional module (2) that is capable of for performing a current-switching function, and an additional functional module (5) for performing at least one function requiring an electrical power supply. The function of the additional functional module (5) is a function requiring an electrical power supply with the exception of a lighting function.

Abstract: A mechanical switch (10), in particular a light switch and/or a roller shutter switch and/or thermostat switch is provided. The mechanical switch (10) has a switching contact assembly (20), in particular a monostable, bistable or tristable switching contact assembly (20), and a base carrier (40), in which the switching contact assembly (20) is received The base carrier (40) has a holding device (50) for receiving an electromechanical actuator unit (100), which is designed in such a way that an electromechanical actuator unit (100) received in the holding device (50) can be supplied with voltage for effecting a state change of the switching contact assembly (20) independently of an external mechanical action on an operating mechanism by means of the electromechanical actuator unit (100).
