FIELD: electricity.
SUBSTANCE: device includes electronic switch with MOS structure, supplying power to load unit. Electronic switch device and a sequence of resistor and thermal resistor connected to common point of switch and load unit reduce error of relay element actuation level generation with hysteresis that control switching load power supply unit on and off with the help of first and second AND elements. In case of current overload, power is disconnected from load unit.
EFFECT: reduced weight and dimensions of voltage switch, increased precision during changes in open electronic switch depending on temperature.
