Often, in amateur radio designs, there is a need for switching (switching) signal circuits and at the same time there is no desire or ability to use the toggle switch and cables that can “catch” interference or noise, or, for example, from an aesthetic point of view. This module is built on a logic element that controls a quality Fujitsu relay with two independent contact groups. The principle of operation is based on a short-circuit of the “switch” contacts, which leads to the operation of the relay and switching of the contacts that are output to the terminal block, as indicated by the LED display on the board. After turning off the power and re-feeding, the module always switches to NC mode (red LED). The module can be used as a signal selector or for individual needs. A wide range of supply voltages makes the module even more versatile and allows you to use it without using a separate power supply. Maximum switched power - 60W
