Abstract
The utility model discloses a double-control power supply switch which comprises a base and a casing. A push shaft is arranged in the casing, and the top end of the push shaft penetrates through the center at the top end of the base and is fixed at the top end of the base through a sealing ring. A first spring is arranged at the bottom end of the push shaft, and a first spring is fixed on the inner surface of the base fixed at the bottom end of the casing. Simultaneously, one side of the push shaft is connected with a wafer and a silver point wafer which are arranged at the bottom of the base through a second spring and a warping plate, and the other side of the push shaft is connected with a bubble point wafer and a U-shaped-edge bubble wafer which are arranged at the bottom of the base through a cover plate and a spring piece. The double-control power supply switch has the advantages of being clear and flexible in hand feel, remarkable in resilience and attractive and exquisite in appearance, effectively prolongs mechanical service life and improves mechanical performance. The weak current portion of the power supply switch is small in contact resistance and flexible and reliable in on-off switching.
Description
Technical field
The utility model relates to a kind of switch, particularly a kind of two control mains switches.
Background technology
Existing two control mains switch all is to connect 2 pin contacts on the base, middle a spring with 2 feelers is installed, and after carrying out function action on the push shaft, is pressed into certain distance, make the spring feeler with the pin contact between be connected the conducting of formation light current.The diameter of the band feeler spring that therefore uses is little, and elastic force is unstable, and contact resistance is big, when making the push shaft function action, be pressed into the end after, switch weak current part resistance is bigger than normal, loose contact, client complains the switch no power, feel is bad, does not have resilience force; Simultaneously, bottom contact chip part-structure by exerting oneself the unbalanced while, is unfavorable for the stable of contact performance in the conducting contact process.
Summary of the invention
To the shortcoming of existing two control mains switches, the utility model provides a kind of novel two control mains switches.
To achieve these goals, the measure taked of the utility model:
A kind of two control mains switch comprises base, shell, and said enclosure is provided with push shaft, and the push shaft top is passed center, base top and is fixed in the base top through sealing ring; The push shaft bottom is provided with first spring, and first spring is fixed in base inner surface; Base is fixed in the shell bottom; Meanwhile, push shaft one side is connected with contact, the silver point contact that the base bottom is provided with through second spring, seesaw, and the push shaft opposite side is connected with bubble point contact, the U-shaped limit bubble contact that the base bottom is provided with through cover plate, reed.
Bubble contact position, the said limit convex structure that takes the shape of the letter U;
Said bubble point contact, limit bubble contact, contact, silver point contact material are brass H65, and silver is covered on the surface;
Said reed is the circular reed structure, and diameter is 4.0 ± 0.1mm;
Said reed material is a stainless steel, and silver is covered on the surface;
Said cover plate is provided with the anti-shake protection structure of circular reed.
The beneficial effect of the utility model: two control mains switch feels are clear flexibly, and resilience is obvious; Two control mains switch weak current part contact resistances are little, the break-make flexibility and reliability; Aesthetic in appearance, exquisite; Two control mains switches effectively improve performance boost mechanical endurance.

Embodiment
A kind of two control mains switch like Fig. 1, shown in Figure 2, comprises base 1, shell 2, and said shell 2 set inside have push shaft 3, and push shaft 3 tops are passed base center, 1 top and are fixed in base 1 top through sealing ring 9; Push shaft 3 bottoms are provided with first spring, 7, the first springs 7 and are fixed in base 1 inner surface; Base 1 is fixed in shell 2 bottoms; Meanwhile, push shaft 3 one sides are connected with contact 12, the silver point contact 13 that base 1 bottom is provided with through second spring 8, seesaw 4, and push shaft 3 opposite sides are through cover plate 6, and reed 5 steeps contact 11 with bubble point contact 10, limit that base 1 bottom is provided with and is connected.In the actual implementation process of patent, limit bubble contact 11 convex structure that takes the shape of the letter U, this structure has effectively guaranteed effective conducting switching performance of contact and reed; Simultaneously, bubble point contact 10, limit bubble contact 11, contact 12, silver point contact 13 materials are brass H65, and silver is covered on the surface, effectively guarantees the contact resistance performance of contact; In addition; Reed 5 changes the circular reed structure into; Two control mains switch feels are more clear obviously for
this structure can make for diameter, performance boost mechanical endurance; Reed 5 materials are stainless steel, and silver is covered on the surface, effectively guarantee the electric conductivity of reed 5.
Those skilled in the art's simple change and replacement all are within the protection range of the utility model in this area.
