### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    This is a very handy RS-232 Serial Switch Box
  

*by K***. on Reviewed in the United States on June 5, 2021*

I have to say after having some time to try it out this RS-232 Serial Switch Box does exactly what it is supposed to. I use mine to switch between several RS-232 devices for radio communications. I use it for programming radios and for operating an external radio receiver (manufactured before the days of USB radio dongles). It is very stable and does what I need very well. I have no issues with this box to report at all.

*by A***N on Reviewed in the United States on September 23, 2018*

I have been working on a  variety of RS-232 based gadgets to hook to my old Radio Shack Color Computer, and this cheap box saves me a bunch of plugging and unplugging. It's metal and well built and does what it claims to do. The first one I ordered was damaged in shipment and dented, but it was quickly replaced by Amazon.

*by M***L on Reviewed in the United States on November 22, 2017*

This is just what I needed to switch multiple serial ports on my progect. It seems to work well, but the push buttons are a little unsure unless you really press and hold. If you don’t press hard, sometimes the button pops back out and you really don’t know what the switch is set to. I have only had this happen a couple of times. Other than that, it works as intended.
