Embodiment:

To shown in Figure 12, a kind of ultra-thin miniature rotary encoder is combined by a rotation thing 3, base 1, fixed housing 2, contact flat spring 4, a leading-out terminal 5 as Fig. 1.

Wherein, base 1 is a flat pedestal, by angle of circumference direction equal circumference angle fan-shaped a pair of first, second connection point terminal and shared connection point terminal 11 that is the arrangement of broach shape is set in the base cavity, and there is a central through hole 12 in base central authorities on the bottom surface, and this through hole 12 stretches out the location for rotation thing 3 belows and the function of concentric rotation is provided;

Three leading-out terminals 5 are fixedly mounted on the base 1, and the circumference that contacted of five equilibrium contact flat spring 4.

A shell 2, be the support body of a five metals through punching press and bending, its central axis hole 21 stretches out the location for rotation thing top and the function of concentric rotation is provided, and extend four intermediate plates 22 downwards in both side edges, a rectangular opening 23 is respectively arranged on the intermediate plate, be used to withhold base 1, be connected mutually with base 1 and surround a space.
