Quick-break switch with a reinforced pressure point
First Claim
1. An electric switch, with a housing, a contact lever moveable between two end settings and pivotal within the housing, a moveable switch piece and at least one fixed contact which is rigidly mounted in the housing and, in one end setting of the contact lever, is tensioned by said housing, whereby one of the contact lever and the switch piece bears a wedge profile and the other of the switch piece and the contact lever has a switch element resting against the wedge profile where the switch piece in the housing can move along a straight path extending essentially perpendicular to a longitudinal direction of the contact lever, and where the switch element and the wedge profile are pretensioned against each other in a direction running essentially perpendicular to the motion direction of the switch piece, characterized in that the contour of at least one of two wedge surfaces forming the wedge profile sensed by the switching element is curved.

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.

6. An electric switch comprising:
-
a housing; a contact lever movable between two end settings and pivotal within the housing; a movable switch piece; at least one fixed contact rigidly mounted in the housing, the at least one fixed contact, in one end setting of the contact lever, tensioned by the housing; one of the contact lever and the switch piece bearing a wedge profile and the other of the switch piece and the contact lever having a switch element resting against the wedge profile; the switch piece in the housing movable along a straight path extending essentially perpendicular to a longitudinal direction of the contact lever; the switch element and the wedge profile being pretensioned against each other in a direction running essentially perpendicular to the motion direction of the switch piece; and a contour of at least one of two wedge surfaces, forming the wedge profile sensed by the switching element, being curved. - View Dependent Claims (7, 8, 9, 10)
