A position indicator for use in an input coordinate device for providing a desired coordinate point on a position detecting plane, comprises a chassis having both a pen shaped portion formed by a substantially cylindrical portion and a mouse portion including a flat bottom; a first indicating circuit, disposed within the pen shaped portion, including a core body having an end extending externally from the pen shaped portion and a first switch; a second indicating circuit, disposed within the mouse portion, including a second switch; a third switch adapted to inhibit operation of the first indicating circuit when the second indicating circuit is being used; and a movable member extending from the flat bottom such that the member is engageable with the detecting plane when the mouse portion is in use, the member being operably connected to the third switch such that movement of the member when engaged with the detecting plane is effective to operate the third switch so as to render the first indicating circuit inoperative when the mouse portion is in use.
