により、抵抗は段階的に減少することとなる。In the first embodiment shown in FIG. 1, a movable contact part 2 and a fixed contact part 3 are provided inside a rubber switch cover member 1,
A lead wire 4 is connected to the fixed contact portion 3. A spacer 5 is provided between the movable contact portion 2 and the fixed contact portion 3. A spiral flat spring was used as the movable contact portion 2. Further, the upper surface of the fixed contact section 3 that contacts the movable contact section 2 is provided with a plurality of contacts 3A to 3C having different resistance levels. Contact 3A
is set to 100Ω here, contact 3B is 10Ω, contact 3
C was set to lΩ. The fixed contact portion 3 is divided into two parts as shown in FIG. 2, each having contacts 3A to 3C. When the key top part IA of the rubber switch cover member 1 is pressurized, the largest diameter part of the movable contact part 2 made of a spiral flat spring contacts the contact point 3A first, and then the key top part IA is pressed. When pressurized, the portion of the spiral flat spring with the next largest diameter comes into contact with the contact point 3B, and when the key top portion IA is further pressurized, the portion of the spiral flat spring with the smaller diameter comes into contact with the contact point 3C. That is, by contacting the movable contact 2 in order from the contact of the fixed contact portion 3 with the highest resistance, the resistance decreases step by step.
