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.

A light barrier detects an object which interrupts a beam of light of the light barrier. A light transmitter transmits a light beam in the direction of a reflector and a light receiver receives a reflected portion of the light beam. The improved light barrier has a reflector which is made as a cylindrical reflector column having a plurality of retroreflecting elements aligned toward the outer surface. The diameter of the reflector column is considerably smaller than the extent of the light beam perpendicular to the cylinder axis so that an optically effective detection beam of light is formed between the sensor and the reflector column whose cross-section at the sensor is determined by the light transmitter and, in direct proximity to the reflector column. The cross-section is determined by the areal overlap of the light beam with the reflector column.
