Detailed ways

Below in conjunction with the accompanying drawings of the description, the single fire wire double control and multi-control switch of the present utility model will be further described.

Referring to Fig. 2, it is the double control switch K1, K2 of the present utility model, wherein K1 connects 1 live line and 2 communication lines A, B; K2 connects 1 lamp holder line and 2 communication lines A, B, the utility model The connection method of the double-control connecting wire is consistent with the wiring method of the traditional mechanical double-control switch. It can replace the traditional double control switch, and the electrician can also use the touch switch according to the traditional wiring method. The switches K1 and K2 in the utility model are touch switches, which belong to the category of electronic products. When the user touches K1, K1 notifies K2 of a signal. After K2 learns the signal of K1, it turns on or off the lamp according to the signal; , K2 notifies K1 of the signal, and K2 turns on or off the lamp at the same time. Since K1 and K2 are electronic touch switches, they can not only control the lamps to turn on and off, but also have other functions such as backlight indication, remote control function, and timing off.

The A port of the K1 switch is connected to the L wire (fire wire), so that K1 connects the fire wire to the A port of the K2 switch through the A port, the A port of K2 is connected to the K2 lamp head wire, and the other end of the lamp is connected to the N wire (neutral wire) to form a loop. K2 uses single live wire technology from this circuit (single live wire technology can be realized in many ways, but it is not discussed in this patent). The power K2 will get is based on the A port (fire wire) Part of the power is sent to K1 through the B port, and the power received by K1 from K2 is required for the normal operation of the switch.

When K1 and K2 do not need to communicate data, the B port is at a high level relative to the A port, which is used as the power supply for K1 supplied by K2. When any K1 and K2 need to communicate, the level of the B port needs to be pulled down for communication. After the completion, the B port returns to the high level as K2 supplies power to K1. The mutual communication between K1 and K2 can adopt a variety of communication coding methods, such as the length of low level time to indicate the state, or transmit the state according to multi-bit bit codes, or communicate in other coding forms.

Referring to Figure 3, the utility model has a wiring method that the traditional double control switch does not have. The traditional dual control switch can control the same lamp with two switches as shown in Figure 1 at most, and the utility model can achieve 3 switches or even more Multiple switches control the same lamp. As shown in the figure, when the user needs to change the state on the K1 switch, K1 transmits the signal to K2, K3, ... (theoretically, there can be more than N switches connected); K2 changes after receiving the signal The load state of the lamp changes the indication state of the switch at the same time; K3 changes the indication state of the lamp after receiving the signal. When the user needs to change the state on the K2 switch, K2 transmits the signal to K1 and K3, and K1 and K3 change the switch indication state. When the user needs to change the state on the K3 switch, K3 transmits the signal to K1 and K2, K1 changes the switch indication state, K2 changes the switch indication state and changes the lamp state at the same time. As mentioned above, any switch state change can notify other switches, so as to achieve state synchronization and multi-control function.

The A port of the K2 switch is connected to the L line to form a loop with the lamp, and the single live wire technology is used to obtain power, and K2 supplies power to other switches through the B port. When the switch needs to communicate, the corresponding switch will pull down the B port to transmit data, and each switch will change the corresponding switch state after receiving the data. After the communication is completed, the B port will restore the high level to realize the power supply function of K2 to other switches.

Referring to Fig. 4 , it is a multi-channel dual-control wiring diagram of the utility model. L1, L2, and L3 lamps are externally connected to the K2 switch, A and L are connected on the K1 switch, and K2 forms a circuit with the lamp to generate power. The K2 switch can be connected to 3-way lamps or even more. K2 can independently control the lamps. At the same time, through the A and B ports, K1 can also independently control the lamps, so as to achieve multi-channel dual control functions through the A and B ports.

Refer to Figure 5, which adds lamps on K1 on the basis of Figure 2. This figure shows that lamps can be connected to K1, K2, or both K1 and K2. These three methods are all Dual control function can be realized.
