Embodiment Construction

[0030] The present invention will be further described below in conjunction with accompanying drawing.

[0031] Such as figure 1 Shown is a structural diagram of an embodiment of a single live wire switch, including a single live wire unit 10 , a holding unit 20 , an anti-interference unit 30 and a touch unit 40 .

[0032] The n touch pulses P1-Pn output by the touch unit are sent to the anti-interference unit, and the anti-interference unit performs anti-interference processing on the n touch pulses respectively, and the output n control pulses M1-Mn are sent to the holding unit, and the holding unit After the n control pulses are triggered and the status is kept, the output n single live wire on-off control signals G1-Gn are sent to the single live wire unit. n is the number of switches of the single live wire switch, that is, the single live wire switch has n switches.

[0033] The single live wire unit includes a single live wire power-taking module and a single live wir...

Abstract

The invention provides a single firewire switch. The single firewire switch comprises a single firewire unit, a keeping unit, a disturbance rejection unit and a touch unit; and a switch function can be realized by controlling the on-off of a controllable alternating current switching circuit by a capacitive touch key. The single firewire switch provided by the invention can effectively filter the power frequency interference and an interference pulse above the power frequency, that is, a normal touch operation pulse signal, the width of which is greater than a specified value, is allowed to pass, a positive narrow pulse during a negative wide pulse period and a negative narrow pulse during a positive wide pulse period are filtered automatically, and in particular, the filter capacity can be recovered quickly and continuous positive narrow pulse or negative narrow pulse interference signals can be filtered; and besides, the maximum width of the positive narrow pulse and negative narrow pulse which need to be filtered can be adjusted by changing a charge time constant and a discharge time constant respectively. The single firewire switch provided by the invention can be used as a substitute product of a common single firewire switch.

Description

technical field [0001] The invention relates to a control switch of electrical equipment, in particular to a single live wire switch. Background technique [0002] At present, the MCU is used to control the single live wire switch in the market. The MCU is easily affected by various interferences, and the switch is prone to uncontrolled misoperation. The trigger IC module with trigger output, especially the capacitive touch IC, has low anti-interference ability, and the switch is also prone to uncontrolled misoperation. Contents of the invention [0003] In order to solve the problem of prone to malfunction in the existing single live wire switch, the present invention provides a single live wire switch, which includes a single live wire unit, a holding unit, an anti-disturbance unit and a touch unit. [0004] The single live wire unit includes a single live wire power-taking module and a single live wire on-off control module, and is provided with a single live wire inpu...
