Abstract

PURPOSE:One contact of each switch is formed on bimorph along with 1st signal line, and the other contact is formed to the contactor which is formed electrically and mechanically to 2nd signal line. In this way, the assembly is facilitated with attenuated chattering, at the same time realizing low cost.
