Abstract

The utility model discloses a rotary shift switch which comprises a housing. A conductive sheet, a moving contact, a turn button and at least two static contacts are disposed in the housing. The static contacts, like arc lines with the same axle center, are distributed on the housing at intervals. Each static contact is provided with a contact pin that extends downwardly and extends out of the housing. Protruding blocks are arranged on the housing to correspond to positions for mounting the static contacts. A spacing groove matching each protruding block is disposed on each static contact. The moving contact contacted with the conductive sheet is turned to be at different shifts and is contacted and conducted with the static contacts, so that the rotary shift switch is switched among the different shifts. Through a design of the static contacts, the rotary shift switch can still keep a good contact property after being turned for a long period of time. Moreover, the rotary shift switch is simple in overall structure, low in cost, small in size and high in reliability.

Description

The rotation driving switch

Technical field

The utility model relates to a kind of switch, particularly rotates driving switch.

Background technology

Switch refers to that can make an open circuit, make current interruptions or make it flow to the electronic component of other circuit, at present, mechanical switch is divided into by the different operating mode on the market: push type, trigger-type, dial type, rotary, rotary switch has easy to use, there are many gears to regulate, locating the advantage such as reliable is widely used in the various electrical equipment, wherein rotating driving switch is a kind of very general appliance switch, can realize the output of different gears, the gear conversion of rotation driving switch of the prior art is mainly realized by the movable contact spring of conduction and the break-make of fixed touching plate, but this switch product or location at home, the energising poor reliability, and or in order to guarantee the effectively reliability of energising, larger and the complex structure of then again the volume of switch being done, so corresponding needs increase space holds and has improved production cost, therefore needs to improve.

The utility model content

The purpose of this utility model is to provide in order to solve above-mentioned the deficiencies in the prior art still can effectively to switch under a kind of long duration of action, and rotation driving switch simple in structure, that volume is little, cost is low.

To achieve these goals, the rotation driving switch that the utility model is designed, comprise housing, in housing, be provided with conducting strip, movable contact spring, knob and at least two fixed touching plate, described fixed touching plate is concentric camber line gap distribution on housing, be provided with to downward-extension and stretch out the haptic element of housing at fixed touching plate, on housing, be provided with projection with respect to the position that fixed touching plate is installed, be provided with the stopper slot that cooperates with projection at fixed touching plate.

By above-mentioned design, by at housing projection being set, be arranged at the stopper slot that projection cooperates at fixed touching plate, realized in the situation of switch long-term work, still can effectively keep original position, therefore still can effectively contact with movable contact spring.

As preferably: described knob bottom is provided with gag lever post, described gag lever post cooperates with movable contact spring and conducting strip one end simultaneously, be provided with the first fixing hole that cooperates with the gag lever post of movable contact spring at movable contact spring, be provided with the second fixing hole that cooperates with gag lever post at conducting strip, so that whole simple in structure, reduce cost, volume is little by preferred version.

As preferably, play effective fixedly position-limiting action, described housing comprises loam cake and the lower cover of mutual fastening, be provided with the knob installing hole covering, described knob one end stretches out the knob installing hole, under cover and be provided with the gag lever post installing hole, the gag lever post of described knob stretches out the gag lever post installing hole and is combined with jump ring.

In order to play effective reset response, under cover and be provided with spring mounting hole, on spring mounting hole, be combined with limit spring by pad.

The rotation driving switch that the utility model obtains, by above-mentioned design, by at housing projection being set, be arranged at the stopper slot that projection cooperates at fixed touching plate, realized in the situation of switch long-term work, still can effectively keep original position, therefore still can effectively contact with movable contact spring, and overall structure is simple, easy to operate, and volume is little and cost is low.
