The pushbutton symbol shown has two normally closed (NC) contacts and one normally open (NO) contact. This indicates that it is a break-before-make pushbutton, which means that the current path is interrupted before a new connection is made. It is not an ON/OFF pushbutton as it does not have a separate dedicated contact for each position.
