Window lifter goes down, but not always up

Saturday, at the end of the week, the first time the driver-side window went down, but no more up. first at the X-ten attempt. since then, the whole thing happened several times, sometimes you press the switch 20 times and then the disc goes up again. today, the whole thing went without problems and the first time. something was with the switch units, I think to remember. but does this also apply to this problem?
