PURPOSE: To provide a slide switch electrode plate in which the moldability, the plainness, and the contact holding property are excellent, no warpage is generated, and the abrasion of a movable piece can be suppressed.
CONSTITUTION: To 100 pts.wt. of polyamide resin which consists of (A) 20 to 80wt.% of polyamide 66 or a polyamide copolymer 66/6 (the polyamide 6 is 20wt.% or less) whose relative viscosity is 2.7 or higher, (B) 10 to 40wt.% of polyamide 6 or a polyamide copolymer 66/6 (the polyamide 66 is 70wt.% or less) whose relative viscosity is less than 2.7, and (C) 10 to 40wt.% of a semiaromatic noncrystal polyamide in which the dicalbxylic acid component consists of isophthalic acid and/or telephthalic acid, (A+B+C=100wt.%), the total amount 20 to 120 pts.wt. of (D) fiber-form reinforcement agent, and (E) kaolin clay are mixed to form a resin composition. In this case, the ratio of the (D) component occupying in the total amount of the (D) and (E) components is made 20 to 45wt.%.
