Abstract
Official abstract text for this publication.
A reed for a reed switch and a reed switch are provided. The reed may include a first portion having a first thickness and a first length, a second portion having a second thickness and a second length, and a hinged portion disposed between the first portion and the second portion, the hinged portion having a third thickness and a third length, wherein the third length is less than 150% of the first thickness and the third thickness is less than each of the first thickness and the second thickness. The reed switch may include the reed disposed in an insulating housing with a reed deformer to deform the reed.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of forming a reed for a reed switch, the method comprising: providing an electrically conductive reed; and stamping the electrically conductive reed to form a hinged portion disposed between a first portion and a second portion, and a third portion extending directly from an end of the second portion opposite the hinged portion, in a direction away from the hinged portion, the third portion defining a terminal end of the reed, the first portion having a first thickness and a first length, the second portion having a second thickness and a second length, the hinged portion having a third thickness and a third length, wherein the third length is less than 150% of the first thickness and the third thickness is less than each of the first thickness and the second thickness, and the third portion having a fourth thickness and a fourth length, wherein the fourth thickness is less than the second thickness and greater than the third thickness, the hinged portion having a width that is less than a width of the third portion. 2. The method of claim 1 , wherein stamping the electrically conductive reed to form the hinged portion and the third portion is done in a single stamping operation.
