A switching assembly ( ) having closure elements such as switch valves ( ), for example, for closing intake lines ( ) and an intake manifold ( ) in which the switching assembly is installed. The switching assembly ( ) advantageously is composed of assembly injection-molded valve modules including switch valves ( ) and a frame ( ). Alternatively, the switch valves ( ) may also be injection molded directly in place in the support component ( ). Because it may be pre-assembled, the entire switching assembly ( ) may be easily installed in the intake manifold. In addition, the switching assembly preferably has rotational axes ( ) which lie at a right angle to the alignment of the valves. It is advantageous that each switch valve ( ) has its own rotational axis, thereby avoiding additive tolerances. In this way a part is provided which is economical to produce and which satisfies the sealing requirements for the switching assembly.
