In modern aircraft (that is to say from dawn of glass cockpits), pilots have been taught to reference FMAs (flight mode annunciators) as depicted on the PFD rather than switch positions. As to what mode is selected, a button push is a rumor, an FMA is a fact. Classic example: most Airbus have an electric switch that selects the parking brake and a triple gauge that shows brake pressure. There have been numerous occasions where pilots set the switch to "on" but failed to check the gauge resulting in unintended aircraft movement. Just as in this case, injuries or death can result.
