With the top of location hole.
In above-mentioned technical proposal：
Further, cavity is formed between the axle sleeve and signal source ontology in fitting, flexible press is set in cavity
Casting die and switch contact, the tapered portion that elastic pressing piece is from top to bottom become larger by the socket cap on top, the diameter at middle part
It is constituted with the disc base of lower part, the lower end of elastic pressing piece upper end connection rotary shaft, switch contact is set to elastic pressing
It the lower end of part and is connect with the input terminal of signal source ontology.The design of elastic pressing piece, energy are added using switch contact on piece
Enough smooth feelings improved when switch uses and the pressing stroke for improving switch.
Preferably, the height of the positioning head and the depth of location hole are identical, and the connector is made of elastic material, and two
Depth of the length of connecting rod between a spacing head no more than the through-hole of positioning head；The setting length for limiting connecting rod, can
When using connector so that it is in the state stretched, to be conducive to securely connect signal source ontology and axle sleeve.
Preferably, it there are four the location hole settings, is uniformly distributed around the edge of axle sleeve.
Preferably, the material of the elastic pressing piece is insulating elastic material.Most commonly seen, it is described that elastic pressing is made
The insulating elastic material of part is silica gel.
Preferably, the material of the connector is rubber.
Beneficial effects of the present invention are：
The rotary coding switch of the present invention need not be arrived routinely in use when assembling rotary shaft, axle sleeve and signal source ontology
Holder, only by using the connector being especially arranged, you can securely connect signal source ontology and axle sleeve so that entire
The structure of switch is more simple, and when assembly or disassembly is more convenient.
