What are the elevator bistable switches?
There are two states of pressing the switch
1. It is connected to the normally open point. When the magnet approaches, it becomes a closed state, indicating that the circuit is closed (connected state);
2. The normally closed point, when the magnet is approached, becomes disconnected, indicating that the line is disconnected. A bistable circuit generally has one output terminal and two input terminals (one for each of the "+" and "-" terminals). When the "+" terminal of the input terminal has a trigger signal, the output terminal will immediately change regardless of its original state. It is a high level and has been outputting a high level stably. If there is a trigger signal at the "-" end of the input end, no matter what the original state of the output end is, it will immediately change to a low level, and it will always output a low level stably. This is a bistable circuit.
