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

[0034] 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.

[0035] Such as figure 1 As shown, a two-way single live wire switch includes a switching power supply, a MOS tube power supply module, a relay K1 and a relay K2, 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 slave On the neutral line N that flows back from the load LED1, 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 that flows back through the load LED1 through the relay K1 On N, the relay K2 is connected between the single live wire L and the neutral wire N that flows ba...

Abstract

The invention relates to a two-way single live wire switch, including a switching power supply, a MOS tube power supply module, a relay K1 and a relay K2, the relay K1 is used to control the single live wire L to supply power to the load LED1 or to stop power supply; the relay K2 is used to Control the single live wire L to supply power to the load LED2 or stop power supply; the switching power supply is used to form a loop between the single live wire L and the neutral wire N that returns from the load LED1 to supply power to the whole switch when the relay K1 is disconnected; The MOS tube power supply module is used to generate a pulse voltage drop instead of the switching power supply to supply power to the whole switch when the relay K1 is closed. Due to the characteristics of low internal resistance, small driving current, large load current, low calorific value and large relay load resistance of the MOS power supply module, the present invention makes the state switching fast and convenient, can reduce the interference to the power grid, and can be used at the same time without a zero line On the switch position of 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...
