An actuation apparatus includes a module movably tethered to a base member. Each of the module and base member include a plurality of magnetic elements aligned in a plurality of paired magnet sets such that in a non-actuated condition a repulsive magnetic force generated by each paired magnet set causes separation of the module and base member. Application of an actuation force to an actuation surface of the module, in opposition to the magnetic repulsive force, causes movement of the module toward the base member such that contact is made between terminals defined by the magnetic elements of at least one of the paired magnet sets, to generate an output signal. In an illustrative example, the base member is a steering wheel armature of a vehicle and the module is a wheel hub assembly including an air bag and a hub cover defining the actuation surface.
