The terminal screws are M3 and they just spin without tightening. Would return item, but it is not worth the time or effort. I had to modify them in order to attach wires securely to the terminals.
This was a fine product, the only problem was that the picture is very deceiving. You think you are getting 4 switches, when in reality it is only for one switch. Whichever switch they are selling should be the only one in the picture so that you know exactly what you are getting. The picture should match the description. I was disappointed when one switch showed up instead of four.
As a radio guy, i needed to switch my main antenna to ground sometimes to drain any static charge, Or to leave it completelt disconnected when not in use This switch does it perfectly.
