A molded cover control station having transverse upper and lower grooves spaced apart by a distance less than the vertical dimension of a panel opening has a resilient gasket positioned against a rear flange, the gasket having a resilient protrusion which is received within the lower groove. Insertion of the control station housing from the rear of the panel such that the lower edge of the panel opening engages the resilient protrusion within the lower groove enables the resilient protrusion to be compressed an amount sufficient to enable the upper end of the housing to be swung forwardly through the opening to align the upper groove with an upper edge of the panel opening. The resiliency of the protrusion within the lower groove biases the housing upwardly to effect engagement between the upper groove and upper edge of the panel opening, and a screw carried by the housing is turned inwardly to project into the lower groove just above the lower edge of the panel opening to bear the weight of the control station and prevent the protrusion from being compressed.

In a control station housing adapted for having electrical control apparatus mounted thereto comprising: a substantially vertically oriented panel having an opening therein; said housing having upper and lower transverse grooves open outwardly of said housing for receiving respective upper and lower edges of said panel opening, a vertical dimension between an outer edge of said upper groove and a corresponding edge of said lower groove being greater than a vertical dimension of said opening and a vertical dimension between bottoms of said respective grooves being less than said vertical dimension of said opening, said housing being insertable into said opening to engage said lower groove over said lower edge permitting rotation of an upper surface of said housing through said opening to align said upper groove with said upper edge; resilient means in said lower groove biasing said housing upwardly to effect engagement of said upper groove with said upper edge; and means carried by said housing extendable into said lower groove within said panel opening preventing downward movement of said housing within said opening sufficient to permit disengagement between said upper groove and said upper edge.
