Abstract
An isolation switch includes a plurality of posts connectable to trace lines and/or a ground line at one side of a housing of the switch. Inside the switch, a conducting contact plate can be moved between a bonded mode, where each of the terminals are interconnected, and a test mode, where the contact plate moves, within the housing, electrically isolating each post and allowing for discrete locating.
Claims18
An isolation switch comprising:
- a housing;
- a plurality of posts extending in the housing;
- a contact plate disposed within the housing;
- a plurality of openings in the contact plate, the plurality of openings having respective ones of the plurality of posts extending therethrough;
- and
- a switch accessible from outside of the housing, the switch movable between a bonded position, where each of the plurality of posts are electrically connected via the contact plate, and a test position, where the switch moves the contact plate, within the housing, to electrically disconnect each of the plurality of posts from the contact plate,
- wherein the switch includes a cam lever attached to a back side of the switch, within the housing.

An isolation switch comprising:
- a housing;
- a plurality of posts extending through the housing;
- a contact plate disposed within the housing;
- a plurality of openings in the contact plate, the plurality of openings having respective ones of the plurality of posts extending therethrough;
- and
- a switch accessible from outside of the housing, the switch movable between a bonded position, where each of the plurality of posts are electrically connected via the contact plate, and a test position, where the switch moves the contact plate, entirely within the housing, to electrically disconnect each of the plurality of posts from the contact plate, wherein:
- the switch includes a cam lever attached to a back side of the switch, within the housing;
- the contact plate includes an L-shaped opening for receiving the cam lever therein;
- and
- turning the switch causes the cam lever to rotate between being positioned in a first leg of the L-shaped opening to a second leg of the L-shaped opening.
