Abstract

An improved drive to retain Y-bar switch for bubble devices has a shape that reduces the possibility of bubble replication, thereby increasing operating margin. The new design has, in effect, moved the strong pole position in a leg of the "Y" further away from the tab or stem portion of the "Y".

Improved Drive to Retain Switch

An improved drive to retain Y-bar switch for bubble devices has a shape that reduces the possibility of bubble replication, thereby increasing operating margin. The new design has, in effect, moved the strong pole position in a leg of the "Y" further away from the tab or stem portion of the "Y".

As shown in the drawing, the drive to retain Y-bar switch contains Y-bar element 10, conductor 12, and I-bar 14. The switch is positioned between major loop chevron elements 16, 18, 20, and 22, and minor loop element 24.

When a current is passed through the conductor 12, a bubble located at position "A" near the tab or stem portion of element 10 will propagate to bubble positions "B" and "C" near chevron element 20. When a current is not passed through the conductor 12, a bubble will propagate from position "A" to position "D" at the end of I-bar 14 and then to position "E" on minor loop element 24.
