Overall the switch was fine but short lived. The contacts fail over time and you have to "tinker" with the switch to turn it on. Now it won't turn on until you hold it in the right position (i.e. don't push it in the direction you want). It was cheap so I'm giving it 2 stars because it lasted a year. The usage was low current (drives the output of a PID controller going through a switch and then driving a relay to switch a high load element so the switch only handles the low current needed to turn the relay on).
