description PURPOSE:To provide a ferrule connector which has toughness and has an excellent sliding characteristic and dimensional stability under high humidity and is capable of maintaining a low connection loss over a long period of time by forming this connector of a resin compsn. formed by packing a specific ratio of carbon particulates into a polyphenylene sulfide resin and an optical switch. CONSTITUTION:This ferrule 1 consists of the resin compsn. formed by packing 100 to 150 pts.wt. carbon particulates into l00 pts.wt. polyphenylene sulfide resin. The molding shrinkage rate of the carbon particulates is high and the dimensional stability thereof is poor if the packing rate of these particulates is =150 pts.wt. The more adequate carbon particulates are obtd. by carbonizing and calcining granular and powdery phenolic resins methanol solubility of
