| 摘要 |
The invention relates to an electrical apparatus (10) for controlling a load comprising a first terminal (D), a second terminal (F), a pushbutton (14) and a controlled switch (12) comprising a first input (52) linked to the first terminal (D) and an output (56) linked to the second terminal (F). The controlled switch (12) is designed to selectively connect the first input (52) or a second input (54) to the output (56) as a function of a command (REL) received from an electronic circuit (22). The pushbutton (12) is connected between the first terminal (D) and the second input (54). The electrical apparatus also comprises a photocoupler (24) comprising a first optical emitter electrical circuit (62) associated optically with a second optical receiver electrical circuit (64), the first circuit (62) linking the second input (54) to the second terminal (F) and the second circuit (64) being connected to the electronic circuit (22). |
