Abstract
A multi-place control single live wire switch comprises a single live wire unit, a maintaining unit, an anti-interference unit and a multi-place switching unit. An illuminating lamp or other electrical equipment can be controlled at infinitely many places. The single live wire switch allows normal operation pulse signals with the width larger than a specified value to pass, positive narrow pulses in the negative wide pulse period and negative narrow pulses in the positive wide pulse period are automatically filtered, especially the filtering capacity can be fast restored to filter continuous positive narrow pulse interference signals or negative narrow pulse interference signals, and ascending edge shake or descending edge shake of switching pulses is eliminated. The maximum widths of the positive narrow pulses and the negative narrow pulses needing to be filtered can be adjusted by changing the charging time constant and the discharging time constant. The single live switch can serve as a substitute product for common switches.

When low level becomes high level, A1 current potential is charged to electric capacity C11 by resistance R11 by P1 high level signal and rises,
When reaching the upper limit threshold voltage that the rising of T1, A1 current potential meets and exceeds Schmidt circuit F11 between when charging, A3 is from low
Level becomes high level；When the positive pulse width of P1 is not up to Schmidt's electricity less than T1, charging interval less than T1, A1 current potential
During the upper limit threshold voltage of road F11, P1 becomes low level, and A1 current potential is immediately turned into low level current potential, and A3 maintains low level
State.In Fig. 8, the original state of P1 and A3 is low level.Positive burst pulse 11, positive burst pulse 12, positive burst pulse 13
Width is respectively less than T1, A1 current potential cannot be charged to or exceed the upper limit threshold voltage of Schmidt circuit F11, to A3 shape
State does not affect；The width of the positive pulse 14 of P1 is more than T1, and therefore, the rising edge in the positive pulse 14 of P1 crosses time T1
After, A3 becomes high level from low level.The trailing edge of the positive pulse 14 of P1 makes A3 become low level from high level, P1's
The width of positive pulse 15 is more than T1, and after positive pulse 15 rising edge crosses time T1, A3 becomes high level from low level.P1
The trailing edge of positive pulse 15 make A3 become low level from high level, the positive pulse 16 of P1, positive pulse 17, positive pulse 18

Hurry up, when switching pulse P1 becomes high level from low level, A2 current potential is immediately turned into high level current potential, and A4 is immediately from low electricity
Put down and become high level.P1 signal is slow to electric capacity C21 electric discharge, when switching pulse P1 becomes low level from high level, and A2 electricity
Discharged to electric capacity C21 by resistance R21 by P1 low level signal in position, upon discharging between reach T2, A2 current potential and drop to low
When the lower limit threshold voltage of Schmidt circuit F21, A4 becomes low level from high level；When the negative pulse width of P1 is less than
T2, when discharge time does not declines, less than T2, A2 current potential, the lower limit threshold voltage reaching Schmidt circuit F21, P1 i.e. becomes
High level, A2 current potential is immediately turned into high level current potential, and A4 maintains high level state.In Fig. 8, the original state of P1 and A4

Along making A4 become high level from low level, the negative pulse 20 of P1, the width of negative pulse 21 are respectively less than T2, therefore, and negative pulse
20, A4 is not affected by negative pulse 21, and A4 maintains low level state.Negative pulse 23, negative pulse 24, negative pulse 25,
The width of negative pulse 26 is respectively less than T2, A2 current potential cannot be electric at or below the lower limit threshold of Schmidt circuit F21 through electric discharge
Pressure, does not affect A4 state；The width of the negative pulse 27 of P1 is more than T2, therefore, in the decline of the negative pulse 27 of P1
After crossing time T2, A4 becomes low level from high level.At the rising edge of the negative pulse 27 of P1, A4 becomes from low level
High level.

Level is crossed time T1 after becoming high level and is just become high level.The output A4 of Schmidt circuit F21 is high at switching pulse P1
Keep high level during level, after switching pulse P1 is become low level from high level, cross time T2 just become low level.Or
Saying, when A3 is high level, A4 must be high level；When A4 is low level, A3 must be low level.
In Fig. 8, the original state of A3, A4 is low level, and the output Y of data selector T11 is low level, and data are selected
Selecting device T11 selects A3 as exporting Y and being to maintain low level period at A3.When A3 becomes from low level at edge 30
During high level, output Y becomes high level, and data selector T11 selects A4 as output Y, and now A4 must be high electricity
Flat, maintain the high level state of output Y.When A4 becomes low level at edge 31 from high level, output Y becomes low electricity
Flat, data selector T11 selects A3 as output Y, and now A3 must be low level, maintains the low level shape of output Y
State.When A3 becomes high level at edge 32 from low level, output Y becomes high level, and data selector T11 selects A4
As output Y, now A4 must be high level, maintains the high level state of output Y.
