A thermoplastic air bag cover (10) is provided having a plurality of domes (20) formed on its front cover (12) which enclose switches (32) of at least one multifunctional unitary switching module (22). Preferably, a pair of unitary multifunctional switching modules (22''', 46''') are provided and corresponding raised domes (44) in the front cover (12) sealingly enclose and protect the switches (32) thereof and also serve as switch activation mechanism. In a separate embodiment of the invention, a coupling mechanism (56''') is provided for both mechanically and electrically coupling the first and second unitary switching modules (22''', 46''') together in order to faciliate assembly of the resulting air bag cover (10''').
