MANUFACTURE OF CONTROL SWITCH FOR AUTOMATIC TRANSMISSION

摘要

PURPOSE:To use a material with excellent sliding property and resistance to pressure and abrasion by constituting a cover body with a primary molded body and a secondary molded body. CONSTITUTION:A primary molded body 36 formed with a fixed contact substrate section inserted with a fixed contact plate 12a and a terminal board 30 by primary molding with thermoplastic synthetic resin and a moving body support hole 4 for rotatively holding the rotary shaft of a moving body is constituted. A secondary molded body 40 covering the primary compact 36 is formed by inserting the primary molded body 36 via secondary molding with a synthetic resin material having excellent abrasion resistance and sliding property and strong strength to constitute a cover body. The insulation creeping distance for the conducting portion of the cover body is extended by the rib of the primary molded body 36, and a material with strong strength and excellent sliding property and resistance to pressure and abrasion can be used for the resin material of the secondary molded body 40 by dividing primary molding and secondary molding.
