Abstract
The utility model relates to an electric illuminating switch which has the functions of instant manual control of a switch and automatic switching off after delay-time illumination for some time. The utility model is suitable for controlling lamps in corridors for the domestic buildings of residents or enterprises and institutions, can satisfy the temporary illuminating requirements of transient personnel in the night, and is mainly composed of an installing panel, a control button, a switch base, a spring, a one-way sealing ring, an adjusting pin valve, a fixed contact point and a movable contact point. The disconnected actions of the fixed contact point and the movable contact point can be delayed and controlled by the principle of gas-pressure balance. The utility model has the advantages of simple structure, strong versatility, obvious energy-saving effect, etc.
Description
The utility model relates to a kind of electrical switchgear, and particularly a kind of have instant manual closing turn off the light an electric lighting switch of function of automatic disconnection of turning on light, delay time.
The passageway illuminating lamp in existing residential building building or enterprises and institutions' office, production building etc. adopts traditional manual palpation formula switch control usually.Such switch takes place through regular meeting during use owing to there is not the function of turning off the light automatically of delaying time: be not related to after perhaps opening, make the logical bits of electric light work the waste electric energy until dawn; Perhaps in time turn off the light, but tend to make the person's of turning off the light walking of feeling about in the dark, otherwise provide torch with oneself for oneself, thereby have inconvenience in actual use.
The purpose of this utility model be to provide a kind of can satisfy temporary transient illumination needs, again can saves energy, the electrical switchgear of manually cutting off the electricity supply automatically and turning off the light after continuing a period of time of throwing light on after turning on light immediately.It is achieved in that switch module mainly is made up of fixed contact and moving contact, with the closure/disconnection of the mode control switch of the displacement of air pressure balance interlinked mechanism control moving contact.The air pressure balance interlinked mechanism has the time-delay controlled function, mainly is made up of control button, compression spring, one-way sealing circle and switch base.Wherein control button inside is provided with air cavity and spring location tappet, and arranged outside has spacing convex shoulder; Be correspondingly provided with the metering pin valve of spring positioning chamber and adjustable air leakiness on the switch base; The spring positioning chamber is stretched and is placed in the button air cavity, also locatees between its outside and air cavity inwall and is provided with the one-way sealing circle; Spring is arranged between button and the switch base by positioning chamber and location tappet.When spring was in diastole state, button was in outer bullet state, and the top that the button convex shoulder is stretched in the moving contact reed of its shoulder face top by drive is ordered about moving contact and departed from fixed contact, makes switch be in off-state; When the pushing button, spring is compressed, air in the button air cavity is discharged through the one-way sealing circle, this moment is owing to the one-way of the air flows of sealing ring with under the rebound effect of spring, form bigger negative pressure in the button air cavity, make button temporarily be maintained at down state, moving contact is broken away from the convex shoulder influence, be maintained at and the contacted state of fixed contact, switch is in closure state; After this, under the effect of big negative pressure, metering pin valve is started working in air cavity, extraneous air gently leaks in air cavity, negative pressure in the air cavity is reduced gradually, and this moment, switch still was maintained at closure state, but when negative pressure is reduced to a certain degree, spring tension plays a leading role, button is extrapolated, make moving contact depart from fixed contact under the drive of button convex shoulder, switch returns off-state, thereby cut off the electricity supply the action of turning off the light automatically after the illumination a period of time of realizing delaying time.Because the escape of air degree of metering pin valve is adjustable, so the effectively closed time of switch also is adjustable.
Based on above-mentioned design, electric switch of the present utility model is the same with the conventional electrical switch simple in structure, can accomplish fully aspect product design and the installation dimension compatible.Simultaneously, also can be the same with some civil electrical switch, on the installation and control panel, can arbitrarily increase electromotion pilot lamp etc. is set, function uniqueness, simple in structure, highly versatile, energy-saving effect are remarkable, have obvious practicability and economy, only need can be applicable to any occasion of temporary energising illumination.
Be described in further detail below in conjunction with exemplary embodiments.
Fig. 1 is a front schematic view of the present utility model;
Fig. 2 is an internal structure schematic diagram of the present utility model.
Consult Fig. 1, the positive installation and control panel (1) of the utility model electric switch is provided with control button (2) and location and installation hole (3).
Consult Fig. 2, electric switch of the present utility model mainly is made up of installation and control panel (1), control button (2), spring (6), one-way sealing circle (5), metering pin valve (12), switch base (4) and fixed contact (11) and moving contact (10), wherein: control button (2) inside is provided with air cavity (8) and spring location tappet (7), and arranged outside has convex shoulder (9); Be set with spring positioning chamber (13) on the switch base (4), install and be provided with metering pin valve (12) and one-way sealing circle (5); Spring (6) is installed in the coaxial mutually and corresponding spring positioning chamber (13) and locatees on the tappet (7); One-way sealing circle (5) location is arranged on the outer wall of spring positioning chamber (13), and is flush-mounted in the air cavity (8) thereupon; The spring leaf top of moving contact (10) is stretched in convex shoulder (9) the shoulder face top of control button (2).
During work, press control button (2), spring (6) is compressed, air in the air cavity (8) is discharged by one-way sealing circle (5), because the tension force effect of spring (6) and the one-way of sealing ring (5) make temporary transient formation negative pressure air cavity (8) in, thus make control button (2) temporarily keep in push mode, moving contact (10) is in the state that contacts with fixed contact (11), and switch is in closed operating state; Meanwhile, because the one-way effect of interior negative pressure effect of air cavity (8) and sealing ring (5), metering pin valve (12) with air tiny leakage function is started working, extraneous air slowly leaks into, and the negative pressure in the air cavity (8) is reduced gradually, when the tension force that is reduced to spring (6) plays a leading role, control button (2) is extrapolated, convex shoulder (9) drives moving contact (10) displacement, makes switch place off-state, realizes the automatic action of turning off the light of time-delay.
Claims (2)
1, the special-purpose electric lighting switch of a kind of corridor, mainly be made up of installation and control panel (1), control button (2), spring (6), sealing ring (5), metering pin valve (12), switch base (4) and fixed contact (11) and moving contact (10), it is characterized in that: installation and control panel (1) is provided with control button (2) and location and installation hole (3); Control button (2) inside is provided with air cavity (8) and spring location tappet (7), and arranged outside has convex shoulder (9); Be set with spring positioning chamber (13) on the switch base (4), install and be provided with metering pin valve (12) and one-way sealing circle (5); Spring (6) is installed on mutually and reaches on the location tappet (7) in the coaxial corresponding spring positioning chamber (13); One-way sealing circle (5) location is arranged on the outer wall of spring positioning chamber (13), and is flush-mounted in the air cavity (8) thereupon; The spring leaf top of moving contact (10) is stretched in convex shoulder (9) the shoulder face top of control button (2).
