The invention discloses a single-wire system single-pole double-throw electronic touch switch, which comprises a capacitive touch switch, a touch and master control processing module, a driving power module, a power switch module and a main power module, wherein the capacitive touch switch is connected to the touch and master control processing module, and inputs a switch signal to the touch and master control processing module; the touch and master control processing module controls the power switch module to work; the power switch module supplies power to a load; the main power module provides electric energy for the touch and master control processing module; and the driving power module supplies the power to the other modules. The single-wire system single-pole double-throw electronictouch switch can realize control over the same load at two places, realize the same functions of a mechanical switch by adopting the capacitive electronic touch switch and simultaneously solve the problem of short service lif
