[0002] In existing game controllers, the ABXY keys use springs as conductors welded to the circuit board. The springs are clamped between the key caps and rubber to control the triggering of game functions. However, since the ABXY keys of game controllers need to be used frequently, the existing springs have the problem of short service life.

A conductive switch connected to the circuit board is provided on the circuit board; the key includes: a key seat supported on the circuit board; an intermediate layer supported on the key seat.
