Okay I know you think a switch is a switch and maybe for some it is true. However, this is a well-made polarity switch. I like the feel of a solid and well-built switch. If you know your Switch will be widely used, you'll need some HD and the usage log. This switch does it for me. It is well made, cross-connections are isolated and securely connected. I buy both short term and serviced because I have different uses but either way the switch is worth the price.
