Abstract
Abstract An electric switch having stationary structures, each consisting of a magnetic circuit portion which is energized by a permanent magnet, and an electric circuit portion which is positioned adjacent to that magnetic circuit portion and equipped for the connection with an external electric circuit, and a movable armature structure having a member capable of controlling, upon actuation and in combination with the specific magnetic forces, the magnetic circuit portion concurrently with the electric circuit portion of a like stationary structure of the electric switch.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
155 words
An electric switch mounted on a frame comprising: at least one first structure composed of two parallel spaced members of a magnetically conductive material, a permanent magnet of an electrically nonconductive material disposed within said two members of said first structure adapted to establish at least one U-shaped, open, magnetic circuit, at least one second structure composed of two members covering the outside of said first, U-shaped, structure adapted to establish an open electric circuit, an actuator engagable from the exterior of said switch and movable with respect to at least one said first and one said second structure, at least one armature of a magnetically conductive material disposed within said actuator and opening and closing over the arms of the ''''U'''' and adapted to coact with said first structure and its magnetic circuit, said armature including an element of an electrically conductive material adapted to coact with said second structure and its electric circuit.
Claim 2
Dependent Claim
155 words
An electric switch mounted on a frame comprising: at least one first structure composed of two parallel spaced members of a magnetically conductive material, a permanent magnet of an electrically nonconductive material disposed within said two members of said first structure adapted to establish at least one U-shaped, open, magnetic circuit, at least one second structure composed of two members covering the outside of said first, U-shaped, structure adapted to establish an open electric circuit, an actuator engagable from the exterior of said switch and movable with respect to at least one said first and one said second structure, at least one armature of a magnetically conductive material disposed within said actuator and opening and closing over the arms of the ''''U'''' and adapted to coact with said first structure and its magnetic circuit, said armature including an element of an electrically conductive material adapted to coact with said second structure and its electric circuit.
Claim 3
Dependent Claim
