Abstract

An ultrathin toggle switch comprises a base, a push key, a dynamic contact sheet, a static contact sheet, and an upper cover board that is sleeved onto the base; wherein the dynamic contact sheet and the static contact are corresponded mutually upwards and downwards, the upper cover board is provided with a through hole for the protruding of a poke rod of a pull key, and moving back and forth. The static contact sheet is arranged in the oblong slot on the base, and one end of the dynamic contact sheet is fixed at the end part of the base. The movable end of the dynamic contact sheet becomes to be warped and hung in the air, and the top of the dynamic contact sheet is arranged with a convex arc-shaped shoulder. Dynamic contact points of the dynamic contact sheet correspond to the static contact points of the static contact sheet. The push key has a groove that stretches to the front-end part and gets arranged on the pressed surface. The front end and the rear end of each groove are arranged like a ladder shape. The push key is pushed before and after. The contact points of the dynamic contact points and the static contact points are pushed in succession and made opened or closed. The utility model has simple structure and can be produced without seal glue. According to the demand of the circuitry, only a switch is needed to control one-route, two-route or multi-route circuit in real time. The switch has ultrathin body and reliable performance.

Description

Ultrathin toggle switch

Technical field

The utility model relates to a kind of appliance switch, especially a kind of extra-thin toggle switch.

Background technology

Many toggle switches can only be controlled single phase poaer supply.Though existing toggle switch can be controlled polyphase source simultaneously; because the toggle switch binding post directly embeds from the base left and right sides; again the strip contact pin of terminal tails is cut off; so having one side, exposes outside base the terminal tails sidewall; so the back is with sealing fixedly the time on the cover upper top cover; glue can be along terminal tails at base; overflow in the seam of top cover and on; and then pollute the terminal wall so that the contact site; in order to improve the sealing overflow of this kind structure; usually can be on a base left side; right both sides are respectively inlayed the anti-overflow inserts of a slice and base homogeneous material and are got involved between top cover and the base, not cause the pollution to terminal.But this structure manufacture process is loaded down with trivial details, and the automaticity that wastes time and energy is not high, and volume is thicker.The patent No. is " ZL99236969.7 ", " toggle switch ", provide a kind of terminal to be easy to make, assemble, and can realize automation mechanized operation, lower-cost toggle switch, but because its fixed terminal and movable terminal all are arranged at the Plug Division, and be plugged on this Plug Division in the jack of base, so this toggle switch is the same with traditional toggle switch thicker, in electrical equipment, installs and take more space.

Summary of the invention

The purpose of this utility model is to provide a kind of and is easy to make, assembles, without sealing, the ultra-thin toggle switch of volume.

The technical solution of the utility model is: this ultrathin type toggle switch comprises base, push button, on, following sound sheet and static contact in correspondence with each other, cover is placed on the upper cover plate on the base, upper cover plate is provided with through hole, outside convexedly stretching in for the poke rod on the push button, described static contact is contained in the base, and place on the base on the rectangle depression slot, one end of movable contact spring is fixed in the end of base, on the moving contact and the fixed contact on the static contact on its movable end, following corresponding, the movable end of moving contact is tilted upward and is hanging shape, and is provided with the recessed shoulder of arc, before push button, the back slip makes movable contact spring contact with static contact and separates when pushing; The alternate groove that extends leading section that is provided with on the press surface of described push button, this groove is relative with the movable contact spring of below, and the front and back end of each groove is stairstepping successively from short to long and arranges; Respectively caving on the described base, formed partition is provided with several V font spurs between the slot, and the steel ball on the push button press surface slides along the partition on the base is forward and backward; The number of this V font spur equates with dynamic and static contact number on the base.

The utility model compared with prior art, simple in structure, static contact places on the slot of base, movable contact spring one end is connected base end, by push button make contact on the dynamic and static contact mutually closed with separate, thereby can control one the tunnel, the two road or multiplex circuit as required, this volume of switch is ultra-thin, installs on electrical equipment and takies less space.

Fig. 3 is the push button upward view among Fig. 1.

Label among the figure is: 1-static contact, 2-upper cover plate, 3-fixed contact, 4-moving contact, 5-movable contact spring, 6-convex arc-shape convex shoulder, 7-spur, 8-push button, 9-push rod, 10-spring, 11-steel ball, 12-base, 13-connecting portion, 14-groove

Embodiment

As shown in the figure, this ultrathin type toggle switch comprises base 12, push button 8, movable contact spring 5, upper cover plate 2, static contact 1, and the dynamic and static contact 4 and 3 of upper and lower correspondence on the dynamic and static contact.Base 12 is provided with the slot of rectangle depression, and static contact 1 places in the slot of rectangle depression on the base, and static contact can be provided with a slice at least or more than a slice, shown in the present embodiment figure be 3, and alternate being sequentially arranged in the slot.Be fixed on the end of base 12 with the corresponding movable contact spring 5 of static contact by its an end connecting portion 13, its movable end upwarps and is hanging shape, is provided with convex arc-shape convex shoulder 6 in the middle of it.On the base between each slot alternately formed partition be provided with several V font spurs 7, the number of this spur is identical with the sheet number of active and static contact.Push button 8 is positioned on the base 12, and the push rod of push button below is provided with the hole, and steel ball 11 places in the hole, and its bottom is placed with compression spring 10.Corresponding to alternate several grooves that extends leading section 14 that offers of movable contact spring of below, each groove front and back end is stairstepping successively from short to long and arranges on the press surface of push button.Upper cover plate 2 upper shields have through hole in the middle of it on base, convexedly stretch in outside the upper cover plate for push rod 9.The two side of upper cover plate is provided with jack, and when upper cover plate was sleeved on the base, the jack on the upper cover plate sidewall and the bossy body on the base fastened, to finish the assembling between itself and base.

During use, push button pushes away forward, short groove rear wall contacts and compresses the arc shape convex shoulder on the corresponding with it movable contact spring 5 at first on its press surface, make this movable contact spring downward, and make, the closing of contact, this road electric current is logical, slides on the steel ball 11 base partitions simultaneously with it intermittently to collide with first V font spur and sends first " answering " sound, to point out existing one road electric current logical.Control two the tunnel and the multiplex circuit closure successively forward.Therewith in like manner, push button slides backward, disconnects with this control circuit one tunnel, two tunnel and multiplex circuit.
