STANDBY CIRCUIT AND ELECTRIC APPLIANCE COMPRISING SUCH A CIRCUIT

摘要

The present invention relates to an electric standby circuit (4) for an electric appliance. The circuit comprises a switch (41) adapted to open and close an electric connection between a first input (IN1) and an output (OUT) of the circuit (4), and a bistable circuit electrically connected to the switch in order to control the opening and closing thereof. The bistable circuit comprises a first BJT transistor (Q19) of the pnp type and a second BJT transistor (Q12) of the npn type. The first transistor (Q19) is connected to the first input (IN1) through the emitter, and the collector of the first transistor (Q19) is connected to the base of the second transistor (Q12) through a first resistor (R39). The collector of the second transistor (Q12) is connected to the switch (41) and to a second input (IN3) through a second resistor (R40). The base of the first transistor (Q19) is connected to the second input (IN3) through a third resistor (R38).
