Abstract
Abstract A rotary selector switch of molded plastic having a rotor blade overlapping the edge of the stator, with an axially directed rim on the stator around the rotor opening. The face of the stator is divided into sections for the stator clips, by radial ribs. The switch is assembled from a molded blank having a stator portion with a rotor portion attached thereto by an integral web. The rotor portion is parallel to and axially spaced from the stator, in line with the rotor opening. A rotor blade is placed on one side of the rotor with an attachment leg extending into the rotor. An axial force is applied to the rotor, rupturing the web, moving the rotor into the opening of the stator and securing the rotor blade to the rotor.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
117 words
The method for making a rotary switch section from a molded blank having a stator portion with a rotor opening therein and a rotor portion attached thereto by an integral web, the rotor portion being axially spaced from the plane of the stator portion and in alignment with the rotor opening in the stator portion, which comprises placing a rotor blade on one side of the rotor portion with an attachment leg extending into the rotor portion, applying an axial thrust to the rotor portion in the direction toward the stator portion, thereby rupturing the web and bringing the rotor and stator portions into the same planes, and thereby securing the rotor blade to the rotor portion.
Claim 2
Independent Claim
117 words
The method for making a rotary switch section from a molded blank having a stator portion with a rotor opening therein and a rotor portion attached thereto by an integral web, the rotor portion being axially spaced from the plane of the stator portion and in alignment with the rotor opening in the stator portion, which comprises placing a rotor blade on one side of the rotor portion with an attachment leg extending into the rotor portion, applying an axial thrust to the rotor portion in the direction toward the stator portion, thereby rupturing the web and bringing the rotor and stator portions into the same planes, and thereby securing the rotor blade to the rotor portion.
Claim 3
Dependent Claim
35 words
The method for making a rotary switch section as set forth in claim 1, including the step of attaching stator clips to the stator portion after the rotor blade is secured to the rotor portion.
Claim 4
Dependent Claim
59 words
The method for making a rotary switch section as set forth in claim 1, including the steps of inverting the stator-rotor combination, placing a second rotor blade on the other side of the rotor portion, with an attachment leg extending into the rotor portion and applying an axial force to the blade, thereby securing it to the rotor portion.
