[0037] The present utility model adopts a three-control lamp circuit to illustrate the principle of multi-control: 1. There are three-hole switches on both sides and a six-hole switch in the middle. The six-hole switch should first connect the four farthest corners with short diagonal lines; A three-hole switch is connected to the six-hole switch. In actual operation, when the lines are unclear in the tube, the upper connecting pin of A three-hole switch can also be connected to the lower connecting pin of the first group of single-gang double-control switches in the six-hole switch, and the lower connecting pin of A three-hole switch can be connected to the upper connecting pin of the first group of single-gang double-control switches in the six-hole switch; 2. The six-hole switch is connected to B three-hole switch; if more control is needed here, a six-hole switch can be added in the middle. The method is the same as that of three-control, and the effect is that any switch can control the light bulb.
[0038] Separate control: Based on the above points 1 and 2, three single-control switches K1, K2, and K3 are added to form a single-control mode that controls three bulbs separately.
[0039] exist Figure 1 When the light bulb is in the lit state, when any switch is triggered, the light bulb goes out, and then any switch is triggered (including the switch just triggered), the light bulb lights up;
[0040] When the triple switch lights up the bulb, the three single-control switches K1, K2, and K3 connected in series to the bulbs are triggered in sequence, and they will go out respectively. When the single-control switch just triggered is triggered again, the corresponding bulb will light up. The above-mentioned separate control mode can also be controlled to zero for convenience during actual control.
[0041] During the production of this experimental platform, the main problem was the control ideas of dual-control lights and multi-control lights. At the same time, the function of single control was added to the multi-control, with the purpose of inspiring students to learn the effect of knowing one and knowing ten. The production of the multi-control lights in this solution added the function of single control to the multi-control, so that three lights can be controlled at the same time or each light can be controlled separately.
[0042] This multi-link control is not used in real life and is only used for teaching;
[0043] During the wiring process, use a twist knot and do not connect in parallel from the switch terminals. The reason is that hard wire terminals are prone to loose connections.
[0044] The experimental platform of the utility model can also be set to a fault training mode.
[0045] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
