Urgent... Use a foot switch to control two appliances to act separately

It is impossible to achieve without using electronic circuits, the circuit diagram upstairs is imaginative, in fact, when stepping on the foot switch, KA1, KA2, KM1, KM2 are constantly interconnected and interlocked, on, power-off oscillation state, and all stop resetting the circuit after releasing the foot switch.

Find the line that controls the start and stop of the motor with a single button to change, you don't need to relay it, add more intermediate relays to complete it.

Dual-control dust switch.

The electrical connection method to control a light (upstairs with the lights on, downstairs with the lights off) is (assumption: total.

Knife switch. "Upstairs").

1. Turn off the main switch knife.

2. Prepare two dual-control switches (each dual-control switch has upper, lower, right, three contacts); a bundle of red wires for fire; A bundle of blue wires, made.

Zero line. , a bundle of green wires, used as control wires.

3. First of all, open the switch box of these two switches, install these two switches on the wall, and connect the upper and lower contacts of the two dual-control switches with two green wires.

4. Use a red wire to connect the right contact of the switch downstairs (if the switch downstairs has a socket on the left, then this wire can be changed to a brown or black wire), check that the wires do not touch and cover the outer cover of the switch box, and then connect the wire to the bayonet.

Lamp. of one of them.

Terminal. or the center binding post of the screw head), and then connect the other end of the bayonet head (or the threaded sleeve of the screw head) with a blue wire.

5. Connect the end of the blue wire that you just connected to the lamp head to the neutral wire.

6. Take out a red wire and connect it to the right contact of the switch upstairs, if you are a novice and you are connecting this switch circuit for the first time, then I suggest you connect a 10 cm section of this red wire at the end of the connection.

Fuse. Then connect the other end of the fuse to the right contact of that switch, and you connect this red wire to the live wire. The circuit is complete.

7. Make sure that the fuse you just connected is firmly connected, and carefully close the ...... the knife switchIf you see that fuse.

Fusing. If you hear a blasting sound, you have to turn off the main knife switch immediately, but when you find that the main knife switch is automatically disconnected, you should not close it strongly, because this is a phenomenon of short circuit protection. At this point you should recheck the connection of the circuit.

If there is no abnormal situation, then, you should first turn off the main switch (this is very important), then remove the fuse just connected, check that the wires do not touch and cover the outer cover of the switch box, and finally officially connect the red wire to the live wire. Then Brother Yu's entire installation operation is completed.

Both switches should be turned on or off locally. If it is one in the pass, the other Zhao Qi knows that it can be opened, and in turn it can be sent to the pass. I just don't know what electrical appliance you want to control, it's a lamp or...
