Summary of the invention
At the problems referred to above, the purpose of this utility model is to provide a kind of novel delay switch, and this novel delay switch can not only be stablized the effect of the traditional delay switch of performance, and simple in structure, and design is with easy to maintenance, and development cost is lower.
The technical scheme that its technical problem that solves the utility model adopts is: this novel delay switch comprises rectification filtering module, spring button, thyristor, capacitor, current-limiting resistance, solid state relay, housing, two inputs of described rectification filtering module start to exchange fire respectively line and zero line, an output is divided into two-way, connect described capacitor and solid state relay respectively, another output is the described thyristor of serial connection earlier, yet is divided into two-way, one the tunnel connects described capacitor, another road connects described solid state relay after being connected in series described current-limiting resistance again, and two main circuit pins of described solid state relay are linked electrical network by lead with controlled electric light, is connected in series described spring button between the control end of described thyristor and the anode.
Above-mentioned novel delay switch, rectification filtering module at first converts alternating voltage to direct voltage, guide between thyristor anode and the negative electrode, when staff is pressed the instantaneous of spring button, control end has anode potential, it makes thyristor be switched on, after spring button was upspring and disconnected, thyristor still was in on-state, at this moment, capacitor obtains charging, solid state relay is lighted electric light, and after capacitor was full of, electric current was lower than by electric current in the thyristor, thyristor disconnects, powered to solid state relay by capacitor this moment, and behind the capacitor discharge off, relay disconnects the main circuit at electric light place, electric light extinguishes, and the time of electric light time-delay is the temporal summation of capacitor charge and discharge.
As mentioned above, this novel delay switch can not only be stablized the effect of the traditional delay switch of performance, and simple in structure, and design is with easy to maintenance, and development cost is lower.
