Problems solved by technology

[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 Interference in the power grid affects the cleanliness of the power grid

Embodiment Construction

[0032] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0033] Such as figure 1 As shown, a one-way single live wire switch includes a switching power supply, a MOS tube power supply module and a relay K1. The input end of the switching power supply is connected to the single live wire L, and the output end of the switching power supply is connected to the circuit that flows back from the load LED1. On the neutral line N of the MOS tube power supply module, the input terminal of the MOS tube power supply module is connected to the single live line L, and the output terminal of the MOS tube power supply module is connected to the neutral line N returned by the load LED1 through the relay K1; The relay K1 is used to control the single live wire L to supply power to the loa...

Abstract

The invention relates to a one-way single fire wire switch, comprising a switch power supply, an MOS (Metal Oxide Semiconductor) transistor power supply module and a relay K1, wherein the relay K1 is used for controlling a single fire wire L to supply power or stop supplying power to a load LED1; the switch power supply is used for forming a circuit between the single fire wire L and a zero line N returned from the load LED1 when the relay K1 is opened so as to supply power to the overall switch; and the MOS transistor power supply module is used for generating a pulse voltage drop when the relay K1 is closed so as to replace the switch power supply to supply power to the overall switch. Due to the characteristics of low internal resistance of the MOS power supply module, low drive current, high load current, low heating quantity and high impact resistance of the relay and the load, the switch is quick and convenient in state switching, can reduce the interference to a grid and simultaneously can be used on a switch position having no zero line N.

Description

technical field [0001] The invention relates to a touch switch, in particular to a 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 one-way single live wire switch, whic...
