A programmable logic switch (1) for controlling electrical utilities (3), has multiple control devices (2) of the electrical utilities (3), a serial interface (5) for connecting the switch (1) to an electrical bus (6) to which other switches (1) can be connected. The serial interface (5) is configured for receiving input signals (7) from other switches (1) and transmitting output signals (8) towards other switches (1). The switch (1) comprises an output device (12) having output channels (13) connectable to the electrical utilities (3) and separate with respect to the serial interface (5), and being configured for generating control signals (14) of the electrical utilities (3) as a function of any combination of signals chosen among control signals (4), programming signals (10) and input signals (7), so to control the electrical utilities (3) as a function of a command operated by a user and programming data.
