I want to turn the double control switch into a single control switch to draw.

Double-control switch, also known as double-control switch, is generally used in two different places, such as the upper and lower floors of stairs or the two ends of walkways, and can independently control the lighting or extinguishing of the same lamp. As shown in the figure, three different connections are provided. S 1 and s2 are 1×2 SPDT switches, which can independently control the on or off of the lamp e. The connection in Figure (b) is easy to install, because each switch has a phase line and a zero line of the power supply, but special attention should be paid to the short circuit at both ends of the phase line and the zero line during maintenance.
