Abstract

The invention relates to a two-path single-live-wire switch comprising a switching power supply, an MOS tube power supply module, a relay K1 and a relay K2. The relay K1 is used for controlling power supplying or stopping of power supplying for a load LED1 by a single live wire L; the relay K2 is used for controlling power supplying or stopping of power supplying for a load LED2 by the single live wire L; the switching power supply is used for forming a loop between the single live wire L and a zero line N returning from the load LED1 when the relay K1 is disconnected; and the MOS tube power supply module is used for generating a pulse voltage drop when the relay K1 is turned off to replace the switching power supply to provide power for the switch. Because of characteristics of low internal resistance, low drive current, large load current, and low heating amount of the MOS tube power supply module and large load and good anti-impact performance of the relays, state switching becomes rapid and convenient, so that the interference on the power grid can be reduced; and the two-path single-live-wire switch can be applied to a switch position without a zero line N.

Description

technical field [0001] The invention relates to a touch switch, in particular to a two-way single live wire switch. Background technique [0002] Existing intelligent switches are realized by adopting the power supply mode of zero live wire and the single fire power supply method of thyristor; the switch of zero live wire needs the power supply of neutral wire and live wire, but most of the installed lighting switch circuit switch positions are not arranged at present. The zero line, so the market utilization rate is not high; the circuit using the thyristor single fire power supply method will have a flickering problem for low-power LED lamps, and according to the characteristics of the thyristor, if it is used on a large scale, it will affect the The power grid produces interference, which affects the cleanliness of the power grid. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a two-way single live wire swit...
