Abstract

The utility model relates to a mechanical indication switch, which consists of a latch fitting, a silver contact, a button, a transparent window, a switch shell and a movable contact piece, and is characterized in the button, the transparent window and the latch fitting of the switch. The transparent indication window is embedded onto the button, the latching fitting is arranged below the transparent window, the latching fitting is similar to a trapezoid shape which has a small upper end and a large lower end, both a top and a bottom of the latch fitting are an arc surface, the middle part of the latch fitting is provided with a lock hook, the lock hook is arranged inside a lock cavity of the switch shell and is hooked on one end surface of the lock cavity, the upper end of the inclined surface of the lock hook is adhered on the wall of the lock cavity, and an elastic element is arranged below the lock hook. The latch fitting representing a state of the switch can be seen through the transparent window of the button, and the latch fitting representing the other state of the switch cannot be seen. The mechanical indication switch can be applied to various electric appliance products and also can be used for the wall switch.

Description

The machinery indicator cock

Technical field

The utility model relates to the technical field of appliance switch, is a kind of switch with the machinery indication.

Background technology

Electronic technology is in develop rapidly, and increasing product has all been used electron controls technology, and these some electronic apparatus devices also need to finish its mission by human-computer dialogue.Briefly be to finish concrete operation by push-button switches different on the pressing device.Nothing that these some push-button switch overwhelming majority are small voltage weak currents lock push-button switch is characterized in that stroke is very little, and what have is even zero, and it is consistent the most typical in soft-touch control opening with the position of closing.Along with the development of electron controls technology, this class switch is more and more, and is more in the future.Self-locking class and do not have the obvious difference that lock class push-button switch has three aspects, 1. one of function aspects heavy current normally, another one is weak current normally., the stroke in 2. total stroke aspect is very little or zero, the bigger 2.5-5 millimeter of another one.3. the change in location aspect does not have above the fold to change before and after the operation, and another one has visibility point to change.

On same product, exist two dissimilar switches, therefore always wish that at technological layer they can access coordination aspect the outward appearance.Therefore produce from resetting the locking press button switch, before more than ten years, just be applied on the mains switch of colour TV.Along with high speed development of national economy, the raising constantly of living standards of the people, constantly the weeding out the old and bring forth the new of electric equipment products, the product of the more novel electronic apparatus switch of outward appearance is released in market.But high-current switch style in the market and kind are seldom, and the switch of band machinery indication is just fewer, is difficult to satisfy the demand in market.

Summary of the invention

The purpose of this utility model is in order to provide style novel a kind of switch from the self-locking type band machinery indicating structure that resets various in style to market, the characteristics stroke is little, comfortable feel, load are big, can satisfy the needed appliance switch of various electric equipment products innovative design, to satisfy people to the pursuit of fashionable life and the pursuit safe in utilization to electrical equipment.

Design of the present utility model is to carry out improvement design, the patent No. 200920075715.8 on the basis according to a kind of patented technology of push-button switch.

It is made of a kind of mechanical indicator cock latch fitting, silver contact, contact, button, transparency window, switch case and moving contact.The button, transparency window and the latch fitting that it is characterized in that switch.On button, embed a transparent indication window, it below the transparency window latch fitting, it is up-small and down-big like trapezoidal, the lock top and the lock end are cambered surfaces, a middle side has latch hook or two sides that latch hook is all arranged, and it places in the lock chamber of switch case, and hook is in lock chamber one end face, top, inclined-plane is affixed on lock chamber wall, is elastic element below.Enough see a state of its representation switch of latch fitting from the transparency window of button, can't see the another one state of its representation switch of latch fitting.

A kind of mechanical indicator cock can be applied to also can be applied to the switch on wall aspect on the various electric equipment products.

Description of drawings

Below in conjunction with accompanying drawing and example, the utility model is further specified.

Fig. 1 is the structural representation of the logical indication of a kind of mechanical indicator cock.

Fig. 2 is the structural representation that a kind of mechanical indicator cock severed finger shows.

Among the figure, latch fitting (1), silver contact (2), contact (3), contact (4), button (5), transparency window (6), switch case (7) and moving contact (8).

Embodiment

The structural representation of the logical indication of a kind of mechanical indicator cock shown in Figure 1, it is made of latch fitting, silver contact, contact, button, transparency window, switch case and moving contact.The button, transparency window and the latch fitting that it is characterized in that switch.Embed a transparent indication window on button, people can see latch fitting when latch fitting is under transparency window, and it tells people's switch to be in logical state; In Fig. 1, be logical indication for contact (3).And be that severed finger shows to contact (4).

The structural representation that a kind of mechanical indicator cock severed finger shown in Figure 2 shows, it is made of latch fitting, silver contact, contact, button, transparency window, switch case and moving contact.The button, transparency window and the latch fitting that it is characterized in that switch.Embed a transparent indication window on button, people can't see latch fitting when latch fitting is not under transparency window, and it tells people's switch to be in disconnected state; In Fig. 2, be that severed finger shows for contact (3).And be logical indication to contact (4).

Latch fitting is up-small and down-big like trapezoidal, and the lock top and the lock end are cambered surfaces, and a middle side has latch hook or two sides that latch hook is all arranged, it places in the lock chamber of switch case, and hook is in lock chamber one end face, and top, inclined-plane is affixed on lock chamber wall, being elastic element below, is the moving contact of rubber-like in the drawings.Under external force and elastic element effect, make and switch the action of finishing Push And Release about latch fitting.
