PURPOSE:To improve dimensional stability and switch controllability, by embedding a plate shaped switch to be integrally molded with an insert and a skin. CONSTITUTION:A plate shaped switch 3 is embedded between an insert 1 in the reverse side and a soft skin 2 in the front side. An upper end of the switch 3 is closely contacted with the skin 2 and enveloped by an annular dam 4 integrally formed with the insert 1. While the outer of the dam 4 between the insert 1 and the skin 2 is integrally formed by an intermediate molded part 6 equipped with a filler part 5 continued to the reverse side of the insert 1. This intermediate molded part 6 is formed by hard synthetic resin of equal kind to the insert 1 with good adhesiveness to both the insert 1 and the skin 2. |
