Switch device mounting structure

A switch device structure serves to help in stably moving an operation rod. The switch device includes a contact fixing support assembled with an insulation case. The fixing support is formed with multiple openings. A connection board and multiple support members are correspondingly assembled in the openings. The support member has a base section and a neck section, which together define a passage. The operation rod is assembled with an elastic unit and can pass through the passage and the connection board to extend into the fixing support so as to move a wire connection assembly in the case. The switch device structure improves the shortcoming of the conventional switch device that the operation rod is apt to shake and deflect.
