The correct installation method and steps for a multi control wall switch:

The arrangement of optional components and decorative switches should consider the convenience of future life as much as possible. Before construction, it is necessary to repeatedly simulate the living environment after people live, and plan the functional requirements of each room one by one. If some details are lacking, it will bring inconvenience to future life. For example, when the phone suddenly rings while soaking in a comfortable bathtub, and the bathroom is not equipped with a phone, it is neither answer nor not answer, and the leisurely mood is also swept away; Although a bright restaurant is comfortable, it is difficult to watch TV during meals. Similar issues are easily overlooked in terms of circuit layout. Therefore, in large halls, good circuit design often has the shadow of a multi control switch.

Install the dual control wall switch. Next, we will take the dual control switch as an example to explain the installation of the dual control switch:

After learning how to install a single control switch, multi control switches are not difficult for electricians. It is only necessary to pay attention to the connection of the phase line during installation. During installation, it is important to note that each dual control switch has three heads, namely Ll, L2, and L. If dual control is used, it is used in pairs. According to the circuit diagram, connect the L1 and L2 of the two switches, L directly to the phase line, and the L of the other switch is connected to the neutral line through a lamp, Other installation methods are similar to single control switches.
