The inversion portion is formed with a movable contact portion having tongues, and is integrally formed of a resilient metal sheet. A case includes a groove held in engagement with one of the arms and stationary contacts are fixed within the case. A slider includes a push-button portion and a groove held in engagement with the other arm and is slidable with respect to the case.
