Abstract
A switch device capable of increasing the operation speed at the time of reversion of contacts, thereby suppressing generation of arcs, and capable of increasing the contact pressure between the contacts, thereby reducing the bouncing of the contacts. A first rotor plate and a second rotor plate are operatively coupled with each other with a torsion coil spring and when the first rotor plate is rotated, a reversing force from the torsion coil spring causes the contact driving part to engage with or disengage from the contact plate.
