Abstract

The utility model discloses a rotation switch formed by a rotation disk, a central shaft, a movable stopcock plate, and a metal contact. The central shaft passes through the center of the rotation disk, one end of the central shaft is provided with a base seat, and the base seat and the central shaft are respectively located at two sides of the rotation disk; the rotation disk is provided with a through slot at the central shaft side; the movable stopcock plates are respectively at two sides of the through slot; the metal contact is arranged at one connection member of the stopcock at the same side with the central shaft base seat. The utility model can be applied in various appliance products, with the advantage of convenient use, little floor space, and inexpensive circuit for realizing menu function by clockwise/counterclockwise rotation.

Description

A kind of rotary switch

The utility model relates to a kind of switch.

Switch is usually used in the various electric equipment products as a kind of electric elements, so the shape of switch, 26S Proteasome Structure and Function are also different because of the difference of electric equipment products.Common rotary switch is a kind of " phase place " principle switch, when the switch counterclockwise rotates and rotates clockwise, leading or the hysteresis of the phase place of output A, B two paths of signals, could discern by the circuit that cooperates again, this type switch must be equipped with the function that expensive soft, hardware circuit could realize selecting " menu ".

The purpose of this utility model provides a kind of circuit simple in structure, easy to use, that adapted is cheap just can realize selecting " menu " function when dextrorotation, derotation rotary switch.

The purpose of this utility model realizes by following technical measures: a kind of rotary switch, form by rotating disk, central shaft, plug plate and hard contact, described central shaft passes the center of rotating disk, one end of central shaft is provided with a base, and base and central shaft lay respectively at the both sides of rotating disk; The side that described rotating disk is positioned at central shaft is provided with groove, and the plug plate is located at the both sides of groove respectively, connects by connector between the two plug plates; Described hard contact is located at one of them the connector place with the plug plate of central shaft base homonymy.

Further perfect as the utility model function, hard contact is contacted with the inside and outside circle of circuit board contact better, the opposite side that described rotating disk is positioned at central shaft also is provided with groove, the plug plate is located at the both sides of groove respectively, connect by connector between the two plug plates, also be provided with a hard contact at connector place with the plug plate of central shaft base homonymy, this hard contact and the hard contact that is positioned at central shaft base opposite side be intersect corresponding.

Basic principle of the present utility model is: have the rotating disk of hard contact one side to contact with circuit two-sided pcb board is positive, as shown in Figure 7, when the clockwise rotary middle spindle, central shaft driven rotary dish rotates, this moment, two plug plates were shifted to an end, hard contact on it can streak the contact, outer ring 8 in circuit board front, makes its two poles of the earth conducting, is equivalent to by next button; When the inverse clock rotary middle spindle, central shaft driven rotary dish rotates, and this moment, two plug plates were shifted to the other end, and the hard contact on it can streak the inner ring contact 9 in circuit board front, makes its two poles of the earth conducting, is equivalent to by next button; When pressing central shaft, the central shaft base is determined 10 contact the two poles of the earth, circuit board front center spring leaf contact, makes its conducting, promptly by next button.Whole switch just changes, reverse, press and be equivalent to three buttons.When the utility model rotary switch rotates with counterclockwise clockwise, have only one group of closing of contact, independent mutually between three groups of switches, therefore can directly export make-and-break signal.

The utility model rotary switch can be applicable in the multiple electric equipment products, as computor-keyboard, microwave oven, robot, PDA etc., have the advantages that circuit simple in structure, easy to use, that area occupied is little, adapted is cheap just can realize selecting " menu " function when dextrorotation, derotation.

The utility model will be further described below in conjunction with drawings and Examples.
