Pros: They are cheap, easy to install and can be used for both two and three way applications. Cons: I installed 3 dozen of these and most had to be replaced again within 2 weeks to 3 months. Problem: The springs in these switches are strong and give you a nice positive click when you use them. Unfortunately, the thin plastic frame that holds the plastic pins that they pivot around isn't strong enough for a heavy-duty nib. We've had many switches fail in places they weren't even being used - they appear to self-destruct when the spring itself pushes the pin through the plastic frame. I will find similar stories here in user reviews. I've stopped using that brand and started using Electecks, which cost just a little more but are listed as 'commercial' - although they seem much stronger and after a dozen installs, none have failed me .
