Pass-through switch is designed to work together with other pass-through switches in chains. This means that it will only be activated if there is a second, third, etc. pass-through switch in the system.
If you want to control the lighting via walk-through switches using a remote control or mobile phone, it is suggested to install a main switch. This main switch should be connected to a light source that is marked SR or SZ, while all other switches in this circuit are simply marked S. This arrangement allows you to rationally distribute the functions of the switches. At the same time save on the cost of additional lighting control devices.
