A mounting assembly for mounting an electronic module to a control panel. A flange is attached to an electronic module body section. At least one bracket is rotatably attached to the flange. The rotation of the at least one bracket is controllable from the front side of the control panel. When the at least one bracket is tightened a compressive force holding the electronic module body section in place is imparted between the flange, the control panel wall and the at least one bracket. In a preferred embodiment the at least one bracket is two brackets. In the preferred embodiment the two brackets are further controllable from the back side of the control panel. Also, in the preferred embodiment, two bolts are inserted through the flange. Two locking nuts are attached to the two bolts. The electronic module body section has two cavities for housing the two brackets prior to tightening them against the control panel wall. Also, in the preferred embodiment, the flange is removable and the electronic module body section can be bolted to the back of a control panel utilizing bolts rigidly attached to the back of the control panel.
