Abstract
The utility model relates to a two-line double-control type control circuit which comprises two control switches, an electric device and a wire and is characterized in that each control switch consists of a single-pole double-throw switch and two diodes, wherein the two diodes are respectively connected with two static contacts of the single-pole double-throw switch in a manner of polarity reverse connection, and the other ends of the two diodes are connected with the eclectic wire after being electrically connected with each other. The control switches are installed on a box body of a wall switch. The electric appliance is an illuminating lamp, an alarm and a signal lamp. The two-line double-control type control circuit has the beneficial effects that the two diodes are only required to be installed in the existing single-pole double-throw wall switch, so that the production cost is low; the wire is arranged from three strands into two strands, so that the installation is convenient, and the wire is saved; the two-line double-control type control circuit is widely applied to a stair lamp, a bedside lamp and other occasions where the same electric appliance is required to be controlled at different positions; and the service life of the two-line double-control type control circuit is longer than that of a voice operated switch, the illuminating time can be controlled, and the electric energy is saved.
Description
Technical field
The utility model relates to a kind of stair light control circuit, particularly only needs to lay the two wires double control-type control circuit of two strands.
Background technology
Traditional stair light control circuit is provided with ganged switch respectively upstairs downstairs, establishes compenzine at wall paper, and advantage is that reliability is high, the life-span is long, and shortcoming is that comparatively trouble and cost height are installed, and is existing superseded by audio-switch basically.Use audio-switch, only need to lay two strands, save electric wire, shortcoming one is the insufficient sensitivity of many audio-switches, need have a mind to produce the big sound, could start stair light, uses inconvenience; The 2nd, audio-switch self price is higher; The 3rd, failure rate is high, the life-span is short, and total cost is not low; The 4th, all delay time the identical time waste power supply behind each the startup.
The utility model content
The purpose of the utility model is: for addressing the above problem, a kind of two wires double control-type control circuit is provided.
The technical scheme that the utility model adopted is: a kind of two wires double control-type control circuit; Comprise two control switchs, electrical appliance and electric wires; It is characterized in that: said each control switch by a single-pole double-throw switch (SPDT), and two diodes constitute; Said two diodes are serially connected on two fixed contacts of single-pole double-throw switch (SPDT) respectively " polarity is opposite ", link to each other with said electric wire after the other end of said two diodes is electrically connected to each other.
Said control switch is installed in the box body of switch on wall.
Said electrical appliance is illuminating lamp, alarm, signal lamp.
After adopting said structure; Because polarity is connected with two diodes on the contrary in each single-pole double-throw switch (SPDT); Utilize the unidirectional conducting characteristic of diode; When only the hilted broadsword in two switches all points to the consistent diode of polar orientation, just conducting of entire circuit, electrical appliance just work (illuminating lamp is bright).
The beneficial effect of the utility model is: only need two diodes of reverse installation in the switch on wall of former single-pole double throw, production cost is low; It is two strands that wiring is economized by original threeway meropodium, saving wire rod easy for installation; Adaptable across the occasion of need,, two these control switchs are installed on upstairs with downstairs the may command stair light respectively like stair, bedroom etc. at the same electrical appliance of a plurality of Position Control (like illuminating lamp, alarm, signal lamp); Be installed on respectively doorway, bedroom place, with the head of a bed on, the may command bedside lamp is avoided the winter in cold, locate to turn on light or turn off the light in the doorway of standing up.Be longer than audio-switch useful life, lighting hours length is controlled, saves electric energy.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure: 1 first control switch (shown in the frame of broken lines), 2 single-pole double-throw switch (SPDT)s, 3 diodes, 4 illuminating lamps, (shown in the frame of broken lines) closed in 5 second controls.
Embodiment
As shown in Figure 1; A kind of two wires double control-type control circuit; Comprise that first control switch 1, second control close 5, illuminating lamp 4, and electric wire; Each control switch 1 or 5 by a single-pole double-throw switch (SPDT) 2, and two diodes 3 constitute, two diodes are serially connected on two fixed contacts of single-pole double-throw switch (SPDT) respectively " polarity is opposite ", the other end of two diodes 3 back that is electrically connected to each other links to each other with electric wire.
Claims (3)
1. two wires double control-type control circuit; Comprise two control switchs, electrical appliance and electric wires; It is characterized in that: said each control switch by a single-pole double-throw switch (SPDT), and two diodes constitute; Said two diodes are serially connected on two fixed contacts of single-pole double-throw switch (SPDT) respectively " polarity is opposite ", link to each other with said electric wire after the other end of said two diodes is electrically connected to each other.
2. two wires as claimed in claim 1 double control-type control circuit, it is characterized in that: said control switch is installed in the box body of switch on wall.
3. two wires as claimed in claim 2 double control-type control circuit is characterized in that: said electrical appliance is illuminating lamp, alarm, signal lamp.
