Abstract
The utility model relates to a combination switch, comprising a switch casing and a support rack. The support rack is provided with a hollow cylinder which is sheathed with a button rod and a ratchet wheel. Both the button rod and the ratchet wheel are hollow. A button spring is sheathed in the ratchet wheel. The switch casing is connected with the support rack. The switch casing is provided with a dynamic contact sheet at the side adjacent to the ratchet wheel, and the other side of the switch casing is provided with a left static contact sheet and a right static contact sheet. The right static contact sheet is connected with the dynamic contact sheet through conducting material which is copper elastic sheet. A reset spring can be installed between the elastic sheet and the bottom of the switch casing. One end of the reset spring is fixed on the elastic sheet, and the other end is fixed on the bottom of the switch casing. The static contact place between the left static contact sheet and the dynamic contact sheet is copper plating layer or silver plating layer. The utility model has the advantages that the conductivity of the combination switch is better than the traditional four contacts structure; resulting from few contacts, the utility model not only reduces resistance, but also saves cost and improves production efficiency.
Description
Technical field
The utility model relates to a kind of electric elements, is specifically related to a kind of unit switch.
Background technology
At present, most of unit switches have four contacts, i.e. two fixed contacts and two moving contacts, and so, unit switch needs two to touch and close when closure, to close quality requirement very strict thereby each is touched touching of closing.Simultaneously two are touched and close and must keep synchronously, otherwise will influences conductive effect, thereby have determined to conduct electricity of low quality, and the contact is many more, and resistance is big more.In addition, each contact all is coated with argent, and this makes has increased the cost of unit switch on the one hand.Therefore, the unit switch that be badly in need of providing a kind of and conduct electricity very well, resistance is little, cost is low.
The utility model content
The purpose of this utility model provides a kind of unit switch, to solve existing unit switch poor electric conductivity, problem that resistance is big.
The purpose of this utility model is achieved through the following technical solutions:
A kind of unit switch, comprise switch case and installing rack, described installing rack is used for fixing the installation unit switch, installing rack has a hollow circular cylinder, this hollow circular cylinder is with button spindle, ratchet, described button spindle, ratchet are hollow form, are with button spring in the ratchet with sprung push buttons bar when the trip switch; Described switch case is connected with installing rack, switch case next-door neighbour ratchet one side is provided with and can be parallel to the movable contact spring that the ratchet axis moves, the switch case opposite side is provided with the left static contact and the right static contact of external wire, being connected with electric conducting material between described right static contact and movable contact spring is electrically connected realizing, this electric conducting material can be the copper elasticity shell fragment of tool conductivity, in order to increase the elastic force of elasticity shell fragment, can install back-moving spring additional between elasticity shell fragment and switch case bottom simultaneously; The lower end of described button spring contacts with the elasticity shell fragment; One end of described back-moving spring is fixed in the elasticity shell fragment, and an end is fixed in the switch case bottom; The fixed contact place of described movable contact spring and left static contact is copper plate or is silver coating.
The utlity model has following beneficial effect: owing to have only a movable contact spring, need not touch the contract step with other in the closing course, traditional relatively four contact structures of electric conductivity are better; Because number of contacts is less, make that not only resistance reduces, and can save cost, improved production efficiency.

Fig. 1 is the dismounting schematic diagram of unit switch described in the utility model.
Among the figure:
1, switch case; 2, fixed contact; 3, left static contact; 4, movable contact spring; 5, button spring; 6, ratchet; 7, button spindle; 8, installing rack; 9, elasticity shell fragment; 10, back-moving spring; 11, right static contact.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, the described unit switch of the utility model embodiment, comprise switch case 1 and installing rack 8, described installing rack 8 is used for fixing the installation unit switch, installing rack 8 has a hollow circular cylinder, this hollow circular cylinder is with button spindle 7, ratchet 6, and described button spindle 7, ratchet 6 are hollow form, is with button spring 5 in the ratchet 6 with sprung push buttons bar 7 when the trip switch; Described switch case 1 is connected with installing rack 8, switch case 1 next-door neighbour's ratchet 6 one sides are provided with and can be parallel to the movable contact spring 4 that ratchet 6 axis move, switch case 1 opposite side is provided with the left static contact 3 and the right static contact 11 of external wire, described right static contact 11 is connected with electric conducting material with 4 of movable contact springs and is electrically connected with realization, this electric conducting material can be the copper elasticity shell fragment 9 of tool conductivity, in order to increase the elastic force of elasticity shell fragment 9, can install back-moving spring 10 additional between elasticity shell fragment 9 and switch case 1 bottom simultaneously; The lower end of described button spring 5 contacts with elasticity shell fragment 9; One end of described back-moving spring 10 is fixed in elasticity shell fragment 9, one ends and is fixed in switch case 1 bottom; Described movable contact spring 4 is copper plate or is silver coating with fixed contact 2 places of left static contact 3.
In the use, left static contact 3, right static contact 11 be external power supply output, input respectively.When needs conducting loop, press the button bar 7, under the effect of button spring 5 movable contact spring 4 along the direction of ratchet 6 axis left static contact 3 move and with left static contact 3 conductings, and, thereby make left static contact 3,11 conductings of right static contact and then make circuit closed because right static contact 11 and 4 of movable contact springs are connected with copper elasticity shell fragment 9; When the needs cutoff circuit, press the button bar 7 once more, under the effect of ratchet 6, button spring 5, button spindle 7 is upspring; Movable contact spring 4 separates with left static contact 3 under the acting in conjunction of elasticity shell fragment 9, back-moving spring 10 simultaneously, and the loop disconnects.
