A push switch which can have a small separation distance from a side surface of a mounting board, when it is mounted on the mounting board through a step, is disclosed. The push switch includes a substrate having a first surface on which a first fixed contact point and a second fixed contact point surrounding the first fixed contact point are formed, a second surface located opposite to the first surface, a third surface extending from the second surface to a corner in a direction perpendicular to the first surface, and a fourth surface extending from the corner parallel to the first surface, and a conductive movable contact point having a peripheral edge is in contact with the second fixed contact point, and a center contacted by the first fixed contact point when the movable contact point is pressed, and the corner includes a groove recessed with respect to at least one of the third surface and the fourth surface.

Push switch

In a first aspect of the present disclosure, a push switch includes a substrate including a first electrode and a second electrode arranged on an upper surface of the substrate, the second electrode arranged around the first electrode; and a resilient member that is arranged on the second electrode over the first electrode. The substrate includes a recess in a lower surface of the substrate, and the recess is positioned below the first electrode that is arranged on the upper surface of the substrate.

Push switch and electronic device including push switch

A side-push push-button switch is provided in which the strength of a rear surface side of a housing to which a load is particularly applied by outside force caused by the switching operation of a push-button member is increased to stably mount the housing on a circuit board and ensure reliable and secure switching operation. The push-button switch includes a housing, a push-button member, and a holding frame. The housing accommodates a switch contact. The push-button member is disposed on a front-surface center portion of the housing and configured to press the switch contact. The holding frame of a channel shape covers outer surfaces of the housing. Both ends of the holding frame are secured to front-surface side portions of the housing on both sides of the push-button member.
