A multi-instruction switch for enhancing electrical insulation is provided. The multi-instruction switch includes a housing, a common pin and a switching pin set. The housing comprises an accommodating space which includes a conductive elastic plate moving back-and-forth and a support rack therein. The conductive elastic plate includes a normal connection section and a switching connection section. The support rack includes a limiting track. The common pin is normally in electrical contact with the normal connection section in the housing. The switching pin set includes a first pin having a contact section and a second pin having a trigger section. The limiting track includes a first insulation plate, a second insulation plate, and an insulation space between the first and second insulation plates. As such, the present invention enhances the insulation effect by the first and second insulation plates and the insulation space located at the limiting track.
