The House - switch for Christmas tree garlands. The electrical circuit contains a RES9 relay, a 200 μF K50-12 capacitor, two MLT-2 resistors, one MLT820, a D207 diode, a PEV-15 ceramic resistor (seen in Figure 6) and a SP-1 variable resistor, which regulates the frequency of switching garlands. The body is shaped like a house, on the back of which there are two sockets for garlands "GIR-1" and "GIR-2", which, when switched on, flash alternately. At the bottom there is a knob for regulating the switching frequency, and the screws that are located under each of the sockets fasten the PEV-15 resistor. An incandescent switchboard lamp, which is located behind the front panel window, turns on and off together with a garland plugged into the GIR-1 socket. The relay makes one click per every switching from "GIR-1" to "GIR-2" and back.
