  • Quick-break switch with a reinforced pressure point
    Patent number: 6080949
    Abstract: A quick-break switch in which, for switching-over purposes under the spring force (1) of a switching element, the two individual wedge faces of a wedge surface are felt. In order to render the pressure point more perceptible, in particular when the switch is manually operated, the wedge faces are curved. These curves can also help to improve the switching behavior of the switch with respect to the switching process and contact-making.
