The assembly comprises a pair of upper and lower contacts, a slider body for pressing said contacts, a button for pressing said slider body, protrusions provided on respective opposing surfaces of the button and the slider body respectively, a coil spring disposed between the button and the slider body and arranged such that is end portions are forced onto and retained on the protrusions respectively, and a casing for retaining the button in a manner such that the button is vertically movable. By providing the protrusions on the back surface of the button and the bottom of the slider body respectively, the coil spring has its end portions forced, respectively, onto the protrusions to firmly hold the slider body in place. Thus, the components involved become easy to be incorporated into the assembly.
