Abstract
A universal load switch includes convex fixed terminal contacts and convex movable contacts selectively connectable electrically to the terminal contacts. Snap blades forcibly move the movable contacts toward and away from each of the terminal contacts.
Claims29
A load switch, comprising:
- opposed spaced terminals;
- terminal contacts on said opposed spaced terminals;
- a contact blade assembly between said terminal contacts, said contact blade assembly including blade contacts;
- and
- snap blades forcibly moving said contact blade assembly toward and away from both of said terminals,
- wherein the load switch further includes a blade shuttle moving said contact blade assembly between said opposed spaced terminals, said contact blade assembly being spring mounted in said blade shuttle.
3 more elements
A load switch, comprising:
- first and second spaced upper terminal contacts;
- first and second spaced lower terminal contacts;
- a contact blade assembly have a first end disposed between said first upper contact and said first lower contact, and a second end disposed between said second upper contact and said second lower contact;
- contacts of said contact blade assembly for selective engagement with said terminal contacts;
- a blade shuttle for moving said contact blade assembly;
- and
- snap blades forcibly moving said contact blade assembly toward and away from each of said first and second spaced upper and lower terminal contacts,
- wherein the contact blade assembly includes a contact blade located a spaced distance from all of the snap blades.
5 more elements
A load switch comprising:
- first upper and lower terminals having first upper and lower terminal contacts thereon;
- second upper and lower terminals having second upper and lower terminal contacts thereon;
- a plunger assembly;
- a blade shuttle assembly including a blade shuttle and a contact blade assembly disposed in said blade shuttle;
- said contact blade assembly having first and second ends between said first upper and lower terminals and said second upper and lower terminals, respectively;
- upper and lower blade contacts on opposite sides of said contact blade assembly at each of said first and second ends;
- and
- snap blades operatively arranged between said plunger assembly and said blade shuttle for forcibly moving said contact blade assembly toward and away from each of said upper and lower terminals,
- wherein the contact blade assembly includes a contact blade, wherein the load switch is configured such that the snap blades rotate to forcibly move said contact blade assembly, and wherein the load switch is configured such that the contact blade is rotationally stationary when the snap blades rotate to forcibly move said contact blade assembly.
