Cabinet fluorescent lighting circuit diagram

Some electrical control cabinets require lighting when the door is opened (or at night). If fluorescent lighting is used, the fluorescent lighting circuit is shown in Figure 14.

Figure 14 Fluorescent lighting circuit

In Figure 14, the lighting circuit consists of fluorescent tubes, glow starters, ballasts, and switches. When we need to switch lights on and off from two places, the circuit is shown in Figure 15.

Figure 15 A circuit that can turn lights on and off in two places

In Figure 15, S1 and S2 are two switches installed in two places. When S2 is in the ① position, the person in the S1 position can turn the light HL on and off at will by turning the S1 switch to different positions. When S1 is in the ① position, wait until HL lights up. When S1 is in the ② position, the HL light goes out, and the person in the S1 position can turn on and off the light normally. If S2 is in the ② position, then the light HL will turn on when the person in the S1 position moves S1 to the ② position, and the HL light will go out when S1 moves to the ① position.

The person at position S2 controls the light on the same principle as the person at position S1.
