Abstract
A device is provided with at least one control element that can be used to trigger a switching process for electrical or mechanical installations. The control element is positioned in a device housing for the device, such that the control element is designed as a snap disk, which is made of metal, and such that the snap disk has a rim which is connected to the device housing through material engagement and which forms a seal between the device housing and the control element, such that an area of the snap disk that borders the rim is designed as a reversibly deformable uncoupling area.
Claims17
Device with at least one control element, the control element is designed as a snap disk which is made of metal, comprising:
- a housing made of metal;
- and
- a rim portion of the snap disk welded to the housing, forming a seal between the housing and the snap disk such that an area of the snap disk that borders the rim forms a reversibly deformable uncoupling area.
A device with at least one control element, the device comprising:
- a device housing made of metal, the device housing comprising:
- a hole and a circular supporting rim having a larger diameter than the hole, the circular supporting rim forming a reception plane;
- a snap disk made of metal, the snap disk comprising:
- a rim portion, an uncoupling area, a concave shoulder, and a convex cap arranged concentrically, the snap disk being positioned on the receiving plane of the device housing and the rim portion of the snap disk being welded the to the device housing, forming a seal between the device housing and the snap disk;
- and
- an electrical switching element positioned inside the device housing and below the snap disk,
- whereby an actuating force exerted on the snap disk moves the snap disk from a stable condition to a meta-stable condition and actuates the switching element below the snap disk, the convex cap becoming concave and the concave shoulder becoming convex in the meta-stable condition, and
- wherein the snap disk snaps back to the stable condition upon removal of the actuating force.
