Abstract
The utility model relates to a manual electric switch which can be automatically opened (or closed) while time delay is generated. The utility model can save electricity and avoid an electricity wasting phenomenon which is caused by that people forget to close a lamp. A bowl-shaped concave component is arranged on an operation lever of the utility model; thus, the gas in the component can be expelled by utilizing a button, and a concave bowl cavity is adsorbed on the working surface of an outer shell. A pressure relief device is utilized to relieve the negative pressure in the inner cavity of the concave bowl, so the goal that the utility model is automatically opened in the time delay can be realized.
Description
The utility model relates to a kind of manual power switch.It is by fixed contact,, moving contact, hinge, lever, resetting means, button, shell constitute.
The switching of existing manual power switch need be carried out twice operation, i.e. a closed procedure, an opening operation.This switch has many inconvenience when being used to control the light fixture of aisle, stair, as open night aisle or stair light fixture the time electricity wasting, and when closing, will influence personnel's walking.And for example switch often places an end in aisle, driving is opened lamp by the switch place, and it is impossible to desire to turn off the light when the pedestrian walks to the other end in aisle again, be head it off, the existing method of using always is the cross complaint problem of switch being installed at the two ends, aisle and realizing two switches with the method that changes the circuit connection.In addition, existing manual power switch can't be avoided will causing the phenomenon of electricity wasting when the pedestrian forgets because of fault when turning off the light.
It is a kind of behind closed procedure that the purpose of this utility model is to provide, and a period of time that lags behind need not to operate once more the manual power switch that can open voluntarily.
The utility model architectural feature is as follows: a cancave bowl shaped member of being made by flexible material is set on the lever of handling the moving contact motion, bright and clean smooth working face is set below this member, and on cancave bowl shaped member or above-mentioned working face, settles pressure relief device.The switch that forms like this, when with hand push switch button, the closure state that is kept moving contact and fixed contact owing to the cancave bowl shaped member by absorption, in period of time hereafter, pressure relief device enters in the chamber gas gradually outside chamber of cancave bowl, make in the chamber to become normal pressure by negative pressure, finally lose absorption power, so lever sets back under the resetting means effect and puts, drive the contact action simultaneously, make switch come back to open-circuit condition.
Cancave bowl shaped member of the present utility model can be made of flexible materials such as plastics or rubber.
Pressure relief device of the present utility model, the simplest is to open a tiny hole on the cancave bowl shaped member, realizes release Time Delay Opening switching purposes with aperture.As another kind of implementation, also can on the working face that cooperates with the cancave bowl shaped member on the switch base, open a pore, utilize the pore release.Also can on this pore, link a throttling arrangement,, utilize throttling arrangement to adjust release speed, to change the time interval of Time Delay Opening switch as the device of valve and so on.
Also can adorn a locking device between shell of the present utility model and button, for example on button, put out flange, the groove that cooperates disposal-L type on shell with button makes after adopting this mode to press the button button along laterally rotation, and flange is snapped in the translot of L type groove.So, can make the utility model have concurrently existing switch often between closed performance.
The above is the switch of often opening at need, utilizes above-mentioned technical characterictic also can make normally closed switch, and this point is conspicuous for those of ordinary skill.
Advantage of the present utility model, the time delayed turn-off that is to adopt utmost point simple means to realize hand switch (or closed), and when turn-offing (or closed), need not external energy.Use the utility model in many occasions, can save electric power in a large number, and can avoid causing the electricity wasting force phenomenon because of the people forgets to turn off the light.
Accompanying drawing provides the schematic diagram of most preferred embodiment of the present utility model.Situation about disconnecting for switch among the figure, this moment, cancave bowl shaped member 3 was separated with the working face 9 of shell 12, fixed contact 1 is separated with moving contact 2, back-moving spring 4 is in punctured position, when pressing shift knob 7,3 with 9 adhesives mutually, lever 5 is around hinge 6 rotating band moving contacts 2 and contact 1 closure, simultaneously with spring 4 tension,, under spring 4 effects, opened in 1 and 2 minute when outside air makes the negative pressure removal after choke valve 11 and pore 10 enter chamber 13.
Claims (2)
1, a kind of manual power switch, constitute by fixed contact, moving contact, hinge, lever, shell, button, resetting means, it is characterized in that having on the lever cancave bowl shaped member of a flexible material system and the working face on the correspondence position shell with it, cancave bowl shaped member or working face are provided with pressure relief device, pressure relief device is the pore of opening on recessed many shapes member or the working face, or link a throttling arrangement on this pore, and keep pressure relief device to be communicated with the chamber of cancave bowl body.
2, manual power switch according to claim 1 is characterized in that there is locking device the cooperation place of shell and button.
