For the sake of technicality, a sensor is a device that changes a physical quantity in to a signal.
In that regard, the terminology is correct, and your statement could still stand.
However, I still doubt a piece of dust could prevent a physical lever and micro switch system from operating. In the case of the PTW, it's a lever (the bolt stop) that rests on a micro switch. As long as the magazine has rounds in it, it will keep the switch depressed and the circuit closed, allowing it to fire.
When the rounds in the magazine empties, the follower will push the bolt stop lever up, which releases pressure on the micro switch, and will open the electrical circuit, denying the system the ability to fire.
When I'd read 'sensor', I thought you were referring to an optical sensor, which is what's used in the gearbox, as i still can't picture any way a piece of dust could trip the physical switch open. However, I can see a chunk of dust blocking the optical sensor which would cause timing issues (but still not an outright failure - the gun could still fire, although with sporadic results - this is a known issue when too much grease is slopped on the gears)
