A watch type terminal, comprising: a body having a band formed to be wearable on a user's wrist; a display coupled to the body; a crown portion extending from the body and being configured to be rotated about an axis in response to a first applied force and being further configured to linearly extend from the body in response to a second applied force; characterized in that the watch type terminal further comprises: a sensing unit including a dome switch, configured to sense the rotation and the extension of a crown element, wherein the dome switch is formed to sense a first state of the crown portion in which the crown portion is completely inserted, a second state when the crown portion is extended by a first distance, and a third state when the crown portion is extended by a second distance that is greater than the first distance; and a controller configured to: cause changing of a display mode of the display based on extension of the crown portion from the body; cause changing of information displayed on the display based on rotation about the axis of the crown portion; cause the display to switch from a time screen indicating a current time in the first state to a first notification screen associated with one event of at least one of events that have been issued, when the crown portion is switched from the first state to the third state; cause the display to switch from the first notification screen to a second notification screen associated with another event of at least one of events that have been issued, when the crown portion is rotated at the third state; and cause the display to switch from the second notification screen to the time screen when the third state is changed to the first state. a body having a band formed to be wearable on a user's wrist;
