A four-way switch including a knob configured to be tilted in four directions to perform a switching operation in the four directions; a housing to which the knob is attached in a tiltable manner; a stopper formed on a surface of the housing so as to protrude by a predetermined height, the stopper being configured to limit a downward motion of the knob by contacting a portion of a lower surface of the knob while the knob is tilted; a guide protrusion formed on the lower surface of the knob so as to protrude by a predetermined length; and a guide groove portion formed on the surface of the housing so as to protrude by a predetermined height so as to face the guide protrusion, the guide groove portion including a recess portion having a structure that engages with the guide protrusion.

A key module (110) for a keyboard is presented. The key module (110) comprises a key tappet (220). The key tappet (220) comprises a coupling portion (322) for coupling with a keycap for the key module (110). The key tappet (220) comprises at least one guiding portion (326, 328) for guiding a translational actuation movement of the key tappet (220) between a rest position and an actuated position. The key tappet (220) comprises at least one tappet stop (324) for limiting the actuation movement. The key module (110) also comprises a trigger element (350) for triggering a switch signal of the key module (110) in response to the actuation movement. The trigger element (350) is attachable to the key tappet (220). The key module (110) further comprises a module housing (230), wherein the module housing (230) is integrally formed. The module housing (230) comprises at least one positioning protrusion (334) for positioning the key module (110) and a circuit substrate of the keyboard. The module housing (230) is formed to movably accommodate the key tappet (220), in order to enable the actuation movement of the key tappet (220) relative to the module housing (230). The module housing (230) comprises at least one housing stop (332) for abutment against the at least one tappet stop (324) of the key tappet (220) in the rest position of the key tappet (220). Moreover, the key module (110) comprises elastic means (340). The elastic means (340) is configured to bias the key tappet (220) into the rest position in an assembled state of the key module (110).

A key device includes a substrate, a key cap and a restoring member. The substrate includes a top surface and two pivot seats protruding on the top surface. The pivot seats are spaced from each other. Each pivot seat has an eave portion laterally extending from a top thereof. The eave portion has a bottom edge. The key cap is above the top surface. The key cap includes a side edge and two extending arms extending from the side edge. An end of each extending arm has a pivoting portion. The pivoting portions pivotally abut against the bottom edges of the eave portions respectively without contacting the top surface of the substrate.
