Tlipiec, no worries I totally understand , you are not familiar with this kind of system. About the sector pay, you overestimated the numbers a little. My infos on the wages are approximativ and not definitiv. From what I was told, your salary depends on the number of sector you do per day and their length. Then you have a scale for those different rates.
As a FO afer the training, you should be around 35k brutto but then have to substract the TR deduction from your salary.
And yes from what I have the salary is subject to the Swiss tax system
