Terminals and switching methods are provided. The terminal includes: a first component (11) connected to a second component (13) via a connection unit (12), the second component (13) being connected to the connection unit (12), and the first (11) and second (13) components being in a first relative position relationship when the connection unit (12) is in the first connection state, or in a second relative position relationship when the connection unit (12) is in the second connection state; a detection unit (14) configured to detect a relative position relationship between the first (11) and second (13) components, and generate a first detection result upon detection of the first relative position relationship, or a second detection result upon detection of the second relative position relationship; and a switching unit (15) connected to the detection unit (14) and configured to switch the terminal to a first operation state based on the first detection result, or to a second operation state based on the second detection result. The terminal includes a first operating system and a second operating system. The first operation state is an operation state in which the first operating system is primarily used, and the second operation state is an operation state in which the second operating system is primarily used.
