A DIN rail mounted device that may be mounted to a DIN rail with minimal components and without requiring the use of tools. In some instances, an electrical device is provided that has one or more integrally formed rigid latches and one or more integrally formed flexible latches. The electrical device may be secured to a DIN rail by first engaging the rigid latches along an upper edge of the DIN rail, and then rotating the device downwards to engage the flexible latches along a lower edge of the DIN rail. The electrical device may be removed by pushing the device upwards, thereby bending the flexible latches downward to a degree where the rigid latches disengage the upper edge of the DIN rail, and then rotating the device forward and down. The flexible latches may be adapted to compress sufficiently to permit this downward travel, and a recess or other opening may be provided behind the flexible latches to allow such movement.
