A linear switch is an electronic component that achieves circuit on-off control through a linear pressing action. Its core structure includes a gating terminal, an input terminal, and an output terminal, relying on spring components to complete synchronous switching of mechanical transmission and electrical signals. According to the operation mode, it can be divided into self-locking type (with a locking spring to maintain the state) and non-locking self-resetting type (automatically resetting after pressing).

This switch is widely used in home appliances, industrial equipment, and other fields. Typical application scenarios include channel switching for televisions, band conversion for recorders, and circuit control for instruments and meters.
