  • Switch and method for disconnecting a switch
    Patent number: 10720291
    Abstract: A switch including a housing, a first contact arrangement having a first commutation contact element and a first contact, a second contact arrangement having a second commutation contact element and a second contact, and also a nominal contact arrangement. The first commutation contact element and the second commutation contact element form a snap-action connection with one another in the closed position of the commutation contact element. When the switch is closed, a distance between the first contact and the second contact is smaller than a distance between the first commutation contact element and the second commutation contact element in the direction of the axis.
