  We present a dual-species oven and Zeeman slower setup capable of producing
slow, high-flux atomic beams for loading magneto-optical traps. Our compact and
versatile system is based on electronic switching between different magnetic
field profiles and is applicable to a wide range of multi-species experiments.
We give details of the vacuum setup, coils and simple electronic circuitry. In
addition, we demonstrate the performance of our system by optimized, sequential
loading of magneto-optical traps of lithium-6 and cesium-133.
