Zusammenfassung:	A closing edge safety device that triggers a safety response upon contact with an obstacle. The body of the safety device is an elastically deformable profile element that encloses a switch chamber containing a switching strip that carries an electrical current. A prechamber with a switching nub is placed at the leading edge of the safety device, in front of the switch chamber. When an external force is applied to the leading edge of the safety device, the switching nub transmits the force to the switch chamber, which also deforms, causing an interruption in the electrical current on the switching strip, thereby triggering the desired safety response of the closing edge safety device. The closing edge safety device provides improved response to large-area as well as small-area contact with an obstacle and is also suitable for use as a limit switch.
