Abstract
The utility model discloses a double-line touch time delay outage electronic switch for public places such as corridor, hotel. The electric appliance is connected with the input end of a bridge rectifier circuit after commercial power is connected into the electric appliance in series, the output end of the rectifier circuit is connected with a controlled silicon in parallel, and then the induced human body clutter signals are sent into the controlled silicon control circuit through a touch sheet and are added into a control electrode of the controlled silicon through amplification and the like. The utility model has the advantages of realize that the circuit is simple reliable, and its delay time is irrelevant with the touch time.
Description
The utility model relates to a kind of two wire touch delay cut-off electronic switch that public places such as corridor, hotel use that is used for.
In the prior art, the kind that touches the delay cut-off switch is a lot, as the Chinese patent (publication number: CN2119050U) and " touching the delay cut-off electronic switch " (notification number: the touch switch circuit that publishes of " electronics newspaper " 92 bound volume P51 pages or leaves CN2119050U) for another example that " touches the delay cut-off switch ".Although foregoing circuit becomes better and approaching perfection day by day, but still have following problem: 1, delay time depends on the length of touch time---the inconvenience that this shows sometimes, (the institute's electronics of carrying newspaper above seeing).2, the touch level of most of electronic switch adopts and collects connection altogether, has increased input impedance, and reliability and sensitivity are reduced.3, used components and parts are more, increase cost (the disclosed patent of carrying above seeing).
The purpose of this utility model be to provide a kind of simple in structure, reliability is high, and irrelevant two wire touch delay cut-off electronic switch of delay time and touch time.
Realize that scheme of the present utility model is as follows: external civil power seals in behind the electrical appliance w by D in the utility model
