Yes. If you have a multimeter, use the continuity setting. Pick one of the four posts of the 4-way switch to hook up the source power. Put one lead of the multimeter on this post. Test the other posts to see which one has continuity and which does not. Leave the lead on a post that does not have continuity with your initial post. Now flip the switch. Does it have continuity now? All you have to do is use two posts of your 4-way switch that alternate continuity when you flip the switch. That's all a regular switch is doing, breaking the continuity between your source power and your load.
