«Домик» (КЗРП)

Christmas tree lights switch. It has a circuit with an electromagnetic relay. The body is metal, made in the form of a hut. You can connect two garlands to it, which will be switched on alternately - there are two sockets on the rear panel for this - "GIR-1" and "GIR-2". Also on the rear panel there is a handle of SP-1 regulator. In the window on the front panel, there is a neon lamp (unfortunately, I do not know its type), which lights up and goes out simultaneously with a garland connected to the "GIR 1" socket. Pictures 4 and 5 show the "insides" of the switch: a circuit consisting of a REC 9 relay, a K50-12 capacitor of 200 μF, one D207 diode and five resistors - two MLT-2, one K82 and two M30 (the second is located on the bottom of the panel. The switching frequency is regulated by means of the SP-1 variable resistor. When switching from the first garland to the second, the relay clicks twice, in the opposite case only once.
