Switch device mounting structure

A switch device structure includes at least one contact seat having a first end wall, a second end wall, two sidewalls, an upper section and a bottom section to together define a cavity for arranging a contact assembly. Each of the first and second end walls of the contact seat has a protruding assembling section and an oblique socket directed to the assembling section. The switch device structure includes a contact support equipped with a fixing board. The contact support is formed with latch sections detachably latched with the assembling sections. An operator can use a tool to directly pass through the oblique socket to unlatch the latch section from the assembling section to quickly install/uninstall the contact seat and the contact support. This solves the problem of the conventional switch device that it is troublesome and time-consuming to install/uninstall the contact seat and the contact support.
