The invention relates to an electronic device with a device base for mounting the electronic device on a support, wherein at least one pivot arm is partially taken up in a receptacle of the device base and partially protrudes from the device base, which arm is adjustable about a pivot axis parallel to a contact side of the device base, wherein, in a first setting position of the pivot arm, a first attachment means is arranged outside the receptacle and wherein, in a second setting position of the pivot arm, a second attachment means differing from the first attachment means is arranged outside the receptacle, characterized in that a recess opening into the receptacle is formed on a side wall of the device base, into which recess a locking piece is inserted, which is adjustable between a release position, in which it releases the pivot arm, and a locking position, in which it fixes the pivot arm optionally in the first or in the second setting position. The electronic device can be a control cabinet lamp in particular.
