Embodiment

Be elaborated below in conjunction with the technical scheme of accompanying drawing to the utility model.

As shown in Figure 2, the said rotary encoder switch in the utility model comprises a core 1, support 2, spacer 3, body 4, switch shrapnel 5, fluctuation dish 6 and brush 7; Said support 2 and said body 4 are chimeric, between said support 2 and said body 4, are formed with container cavity; Said support 2 has the pipe of taking out, and said axle core passes the said pipe of taking out, and an end of said axle core 1 is positioned at the outside of said support 2, and its other end passes saidly to be taken out pipe and insert in the said container cavity, and the said other end of said axle core 1 is provided with said fluctuation dish 6.Said spacer 3 is arranged on the said support 2.As shown in Figure 3; In said body 4, be provided with the switch shrapnel installation portion 9 that is used to produce the signal code position 8 of sine wave signal and is used to install said switch shrapnel; Thereby can more reasonably use said body 4, make that only needing that when finished product is assembled said switch shrapnel 5 is assembled into said switch shrapnel installation portion gets final product.Said brush 7 is fixed on the said fluctuation dish 6, and preferably, said brush 7 is fixed on the said fluctuation dish 6 through riveting.The said other end of said axle core 1 can directly contact with said switch shrapnel 5 or separate, thereby realizes the function of push switch.

Preferably, said body also comprises the bonnet that is integrated in one with said body.

The body of said rotary encoder switch also comprises a plurality of switch terminal pin, and said rotary encoder switch also comprises a plurality of sine wave signal lead-out terminal pin; Preferably, said a plurality of switch terminal pin are arranged on a side of said body 4, and said a plurality of sine wave signal lead-out terminal pin is arranged on the opposite side of said body 4.
