I tested each switch with a voltmeter and all switches work smoothly with good contact in both positions. I should add that this review is for 3 pole, 2 pole, 2 position on/off switches. . I see another review that Revain seems to have posted here that doesn't belong here that refers to 3-way on/off/on switches (amusingly labeled NO/OFF/NO). I can't say anything about these switches, but the 2 position switches work perfectly.
