Abstract
Snap action switch with a sheet metal spring divided by slots into two or three coherent strips, one of which is shortened by way of bending. The bending is effected by clamping the strip between abutments formed by the upper and lower part of the housing. In this way a definite bending of the sheet metal spring is obtained.
Claims3
An electrical snap-action switch comprising a snapping spring made of sheet metal divided into at least two strips extending in parallel with one another, with the strips being joined to one another at both ends by cross webs, and of which at least one strip is unshortened, and at least one other strip is shortened by means of a bending, with the sheet metal carrying at least one electric contact cooperating with an opposite contact arranged on a flat base, and in which there is provided an actuating device by which the unshortened strip can be caused to snap over, and including means for clamping said other strip between abutments so that said bending is thereby provided, and wherein the abutments are formed by the switch housing.
