Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an insulating barrier of a power switch having incombustibility and anti-explosive stress property and excellent in tracking resistance and heat resistance. SOLUTION: The power switch 1 includes a switching electrode 7 consisting of a fixed contact 2 and a movable contact 3. The three-phase switching electrode 7 is housed in a container surrounded by the insulating barriers 4 and 5 in a box-like form and an insulating barrier 6 is laminated on the outer side of the container. Each of the insulating barriers 4, 5, 6 is made of a polyamide resin composition prepared by compounding a triazine-based compound B of 3-14 pts.wt. with a polyamide resin A of 100 pts.wt.
