Provided are: a switch device capable of suppressing an occurrence of a mistake in which an attachment is performed in an incorrect attachment direction or arrangement position in an assembly step; and a key input device in which the switch device is disposed. A key switch 1 (switch device) is provided with a fixed member 10 and a movable member 11 for receiving a pushdown operation. Furthermore, the key switch 1 is provided with: a plurality of light sources that are disposed at different positions in the fixed member 10 and that can emit light individually; an optical member 13 irradiated with the light emitted from the light sources; and a support member 14 that supports the optical member 13. In addition, the optical member 13 has: a lens array in which a plurality of convex lenses are arranged; and a selective transmission layer that selectively transmits refracted light according to the light source that has emitted light. In addition, the support member 14 has a shape that limits the support direction for the optical member 13.
