Abstract
The utility model discloses a time-delay switch circuit, comprising a touch switch K1, a touch switch K2, a resistor R1, a resistor R2, a resistor R3, a resistor R4, a resistor R5, a triode Q1 and a triode Q2. When the K1 is pressed, the Q1 and Q2 are successively conducted, a VO generates output and locks the switch circuit via follow current of the R5; when the K1 is disconnected, the switch circuit continues output; and when the K2 is disconnected, the Q1 and the Q2 are cut off, the switch circuit is disconnected, so disconnection between the power supply and a load circuit is realized without taking out the power supply, therefore, usage is convenient, and energy is saved. The time-delay switch circuit also comprises a resistor R6, a resistor R7, a resistor R8, a capacitor C1, a voltage stabilizing diode Z1, a diode D1 and a MOS tube Q3, thereby providing a function of time delay control.
Description
Technical field
The utility model relates to a kind of control circuit with time-delay and switching function.
Background technology
Electric equipment all needs to adopt control circuit to control usually, as in battery-driven remote control circuitry, the user is not when using a teleswitch, seldom the battery in the remote controller is taken out, battery is powered to load circuit always like this, make battery cause unnecessary loss, and shortened the useful life of battery greatly.
The utility model content
The purpose of this utility model is to overcome above-mentioned defective in the prior art: a kind of delay function that has is provided, do not need the power supply taking-up just can be realized that power supply and load circuit disconnect, and easy to use, the delay switch circuit of energy savings.
For achieving the above object, the technical scheme that the utility model provides is as follows: construct a kind of delay switch circuit, this switching circuit is by touch-switch K1, K2, resistance R 1, R2, R3, R4, R5, triode Q1, Q2 form, and its importation is that VIN is to GND, its output is that V0 is to GND, when pressing touch-switch K1, triode Q1, Q2 conducting in succession, V0 produces output and pins switching circuit by resistance R 5 afterflows; When touch-switch K1 disconnected, switching circuit continued that output is arranged; When touch-switch K2 disconnected, triode Q1, Q2 ended, and switching circuit disconnects.
Also comprise delay circuit, this delay circuit is by resistance R 6, R7, R8, capacitor C 1, voltage stabilizing didoe Z1, diode D1, metal-oxide-semiconductor Q3 forms, and after switching circuit was opened, importation V0 charged to capacitor C 1 by resistance R 6, after charging voltage reaches certain value, voltage stabilizing didoe Z1, metal-oxide-semiconductor Q3 be conducting simultaneously also, and triode Q1, Q2 are ended, and switching circuit cuts out.
The beneficial effect of delay switch circuit described in the utility model is: by constructing by touch-switch K1, K2, resistance R 1, R2, R3, R4, R5, the switching circuit that triode Q1, Q2 form, when pressing touch-switch K1, triode Q1, Q2 conducting in succession, V0 produces output and pins switching circuit by resistance R 5 afterflows; When touch-switch K1 disconnected, switching circuit continued that output is arranged; When touch-switch K2 disconnected, triode Q1, Q2 ended, and switching circuit disconnects, and did not need the power supply taking-up just can be realized that power supply and load circuit disconnect, and be easy to use, energy savings.Also comprise by resistance R 6, R7, R8, capacitor C 1, voltage stabilizing didoe Z1, diode D1, the delay circuit that metal-oxide-semiconductor Q3 forms, thus have the time-delay controlled function.
Below in conjunction with drawings and Examples delay switch circuit described in the utility model is described further:
Description of drawings
Fig. 1 is the circuit theory diagrams of the utility model delay switch circuit.
