Abstract
The utility model relates to a snap-action travel switch which comprises an outer shell and a conductive sheet fixed on the outer shell, wherein, a keystroke extends out of the outer shell. One end of a positioning rod is fixed on the keystroke while the other end of the positioning rod extends into a groove arranged at the bottom of the outer shell, and a restoring spring is sheathed on the positioning rod. The end of the conductive sheet, which is positioned in the outer shell, forms static contacts. A spring bracket is positioned between the two relative static contacts, and a moveable contact is positioned on the spring bracket. One end of an action spring is sheathed on the spring bracket while the other end of the action spring is sheathed on a fixing sheet which is fixed on the positioning rod. The action speed of the switch of the utility model is fast, which can prevent the welding fusion of the contacts or continuous electric arcs, and the utility model has advantages of long mechanical life, long electrical life and convenient wire connection.
Description
A kind of snap-action travel switch relates to the switch with linear operating, particularly relies on the quick acting switch of elastic component distortion.
Chinese patent has disclosed a kind of " pressing key swich " No. 93233382.6, comprises parts such as pressing key head, padlock core, stage clip, housing, panel.The upper end is provided with the key head of pressing that adopts the transparent material making in housing, presses the key head lower end padlock core is set, and padlock core lower end is provided with stage clip.Though the key swich of pressing of said structure has stronger practicality in some aspects.But its contact kind is few, and changing-over speed is slow, thereby makes the application scenario of switch and performance be subjected to great restriction.
The purpose of this utility model provides a kind of snap-action travel switch, and it can prevent contact melting welding or sustained arc effectively, and quick action.
Adopt such technical scheme according to above-mentioned purpose the utility model: this switch comprises a shell, and end conducting strip facing each other is fixed on the shell and extends to housing exterior in shell.Button stretches out in shell, and the partial fixing that button is positioned at shell has link stopper.Described conducting strip end forms fixed contact, and spring(-supported) mount is positioned between two relative fixed contacts, and backstay passes spring(-supported) mount, and moving contact is positioned on the spring(-supported) mount.Operating spring one end is enclosed within on the spring(-supported) mount, and the other end is enclosed within on the stator that is fixed on the backstay.Backstay one end is fixed on the button, and the other end puts in the groove of outer casing bottom, and is with back-moving spring on the backstay.
The utility model is owing to the structure that adopts operating spring and spring(-supported) mount, so switch changing-over speed is fast, and the spacing of fixed contact can design different distance according to different use occasions relatively.Also have simultaneously and contact melting welding does not take place or sustained arc, mechanical endurance and electric life are long, the advantage of easy-to-connect according to the snap-action travel switch that the utility model proposes.
The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is according to the snap-action travel switch structure schematic diagram that the utility model proposes.
Fig. 2 is according to the snap-action travel switch medi-spring shelf structure schematic diagram that the utility model proposes.
Below in conjunction with details and the working condition of accompanying drawing detailed description according to the switch that the utility model proposes.
This switch comprises a shell, as shown in Figure 1.Button (3) stretches out in shell (1), and the partial fixing that button is positioned at shell has link stopper (4), thus unlikely ejection when button is resetted.Backstay (11) one ends are fixed on the button, and the other end puts in the groove (12) of outer casing bottom.Be with back-moving spring (7) on the backstay (11), the shape of this spring is preferably pagoda shape, in order to avoid backstay laterally moves when touching button.End conducting strip facing each other (9) is fixed on the shell, and extends to the outside of shell from enclosure.The end that conducting strip is positioned at enclosure forms fixed contact (8), and the end that is positioned at housing exterior forms binding post.Spring(-supported) mount (2) is positioned between two relative fixed contacts, and backstay passes spring(-supported) mount, and moving contact (10) is positioned on the spring(-supported) mount.Operating spring (6) one ends are enclosed within on the spring(-supported) mount, and the other end is enclosed within on the stator (5) that is fixed on the backstay.The installation site of stator is than spring(-supported) mount height, thus make two moving contacts under nature all the time with the contact of two fixed contacts, constitute normally-closed contact.
The structure of spring(-supported) mount is a hollow frame in the middle part of it as shown in Figure 2, and both ends are moving contact (10).One projection (13) is respectively arranged, so that an end of operating spring is enclosed within on the projection on the frame on the relative edge.
During use, stored energy constantly increases in two operating springs along with button constantly moves down.When moving to critical point, when promptly stator and spring(-supported) mount were in same plane, the energy in the operating spring discharged and impels spring(-supported) mount to go up suddenly to jump, moving contact is contacted with top two fixed contacts.When button resets, pass through critical point once more, spring(-supported) mount is jumped down suddenly, thereby realize quick acting.
Claims (3)
1. a snap-action travel switch comprises a shell, and end conducting strip facing each other is fixed on the shell and extends to housing exterior in shell, and button stretches out in shell, and the partial fixing that button is positioned at shell has link stopper; Described conducting strip end forms fixed contact; Backstay one end is fixed on the button, the other end puts in the groove of outer casing bottom, and be with back-moving spring on the backstay, it is characterized in that spring(-supported) mount is positioned between two relative fixed contacts, backstay passes spring(-supported) mount, moving contact is positioned on the spring(-supported) mount, and operating spring one end is enclosed within that the other end is enclosed within on the stator that is fixed in backstay on the spring(-supported) mount.
2. snap-action travel switch according to claim 1, what it is characterized in that back-moving spring is shaped as pagoda shape.
3. snap-action travel switch according to claim 1, the installation site that it is characterized in that stator is than spring(-supported) mount height.
