A control panel is provided incorporating a plurality of controls and an arrangement for the rapid mounting and demounting thereof in an aperture of a support. The mounting and demounting arrangement permits the retention of the panel with one side of the opening retained in a slot in a corresponding side of the panel and the other side of the opening being retained between a projection and a displaceable dog on the opposite side of said panel. Said dog is mounted on a bolt threaded in said panel for displacement between a first position in which the dog engages the wall of the opening and a second position wherein the dog is displaced both away from the wall of the opening in the axial direction of the bolt and pivoted by the bolt out of registration of the wall to permit release of the panel. The controls may include diaphragm-type push-button switches, slide switches and rotatable multi-position switches.
