Abstract

A pressure sensing switch which prevents the crack and damage when a stress is applied. The pressure-sensing switch extended in an X-Y-direction includes pressure sensing portions arranged in an X-direction and connection portion provided between the pressure sensing portions for connecting the pressure sensing portions. The connection portion includes a straight portion extended in X-direction and a straight portion formed by inverting both ends of the straight portion. The straight portion is deformed in a Y-direction for connecting to the pressure sensing portions.
