I was thinking of popping a clear piece of heat shrink over the 1x/10x button on the Rigol probes so they stay at 10x at all times. The slide moves much too easily.
It depends on the probe. I have 13 of Rigol's 100MHz probes and out of the lot, there are 3-4 that have extremely soft 1X/10X switches that can change position by simply dragging the probe across my antistatic mat, which is indeed very annoying. Most of the others require more direct force.
The reason I have so many probes is because out of my original 8, I had 5 which had very glitchy 1X contact and two of those were hopeless. Last week, I was testing an adjustable load I was putting together and after half an hour of chasing the cause of unstable current and large errors, it turned out that one of my "good" probes was acting up on the 1X position.
Rigol appears to have major QA issues with those switches. They seem outrageously unreliable.
