Push button switch assembly, in particular for insertion in a control panel of a domestic appliance, the push button switch assembly comprising at least one push button and a frame for receiving the at least one push button, wherein the push button has a push button cap, whose top wall or rather upper side is to be manipulated by a user, and an actuating element, in particular an actuating pin, for actuating a switch, especially a micro switch, of a circuit board arranged underneath the push button switch assembly upon actuation of the push button cap, wherein the push button cap is provided with spring legs resting on a frame bottom and counteracting the actuation of the push button cap, characterized in that at least two spring legs are provided, which are formed in a rotationally symmetric or in an axially symmetric arrangement at the push button cap.

Provided are a push switch capable of effectively suppressing a position deviation or a wobble of a slider caused by errors of mold sizes as well as reducing mold cost, and a method of manufacturing the same.

The push switch includes a slider (3) which is supported by a tubular case (2) to reciprocate and is pushed to be operated. Contact inclined surfaces (33a to 36a) of contact convex portions (33 to 36) of the slider (3) come in contact with restriction inclined surfaces (22a to 25a) of restriction concave portions (22 to 25) of the tubular case (2), respectively, the slider (3) upon retreating is returned to a predetermined non-operation position. In addition, the slider (3) is molded by injection-molding a resin material having a higher thermal contraction coefficient and a lower melting temperature than the resin material of the tubular case (2) in a cavity using the tubular case (2) as a part of a mold. Therefore, each contact convex portion has a shape similar to and slightly smaller than a convex portion complementary to the respective restriction concave portion. An interval between the restriction inclined surfaces (22a and 23a) increases in a retreat direction and also increases in an inward direction of the restriction concave portions (22 and 23), which is substantially perpendicular to the retreat direction.

A push button switch is provided, which has a long life, high stability in operation, an operation force and an operation feeling which do not change from the initial state, and a display device which has a wide viewing angle and is capable of realising low power consumption.

A push button switch with a display device comprises a switching body 16 including a case 1 having an opening part 1A on the upper side thereof and a case cover 13 covering the case 1, a switching element 10 provided within the switching body 16, and a plunger 12 protruding upward from a round hole 14 of the case cover 13, wherein up and down movement of the plunger 12 is guided within the switching body 16 to connect with the switching element 10 so as to open and close an electric circuit, the push button switch with a display device further comprises longitudinal grooves 6 provided at four corners of the outer side surfaces 3 of the case 1, metallic round pins 11 having a small friction coefficient fastened to the grooves 6, an operational button 21 covering the switching body 16 and being arranged in convex-concave fitting with the plunger 12, a holder 18 fixed within the operational button by a supporting plate 17, and an organic light emitting display device (organic light emitting diode panel) 19 attached to the holder 18.

Provided is a stable key sheet in which, even if a key top is operated so as to be shifted sidewise, no excessive change, such as great tottering of the key top or overlapping of key tops each other, is caused. A key sheet (10) including: a key top (13) having a fixation protrusion (13b) protruding from a center of a bottom surface; and a base sheet (16) to which the fixation protrusion (13b) is fixed, further includes a stopper plate (17) having an opening (17a) through which the fixation protrusion (13b) of the key top (13) is passed and whose edge faces a side of the fixation protrusion (13b), in which, at a time of sidewise movement of the key top (13), the stopper plate (17) abuts the key top (13) to regulate the sidewise movement of the key top (13).

A remote controller, which enables secure pressing operation of operational buttons, includes a top case (10) having a plurality of through holes (12) and a plurality of operational buttons (31) exposed respectively from the through holes of the top case, so that each of the operational buttons is pressed for controlling equipment. Ribs (13) protrude from the inner surface of the top case along circumferences of the through holes.

Beschrieben wird eine Tastenanordnung für ein elektrisches oder elektronisches Gerät in einem Kraftfahrzeug, mit mindestens einer Taste, die eine Tastenkappe aufweist, die schwimmend auf einem beweglichen Tastenteil aufliegt, und mit einer Tastenblende, die die Tastenkappe umfaßt, wobei die Tastenkappe einen umlaufenden Randbereich ausbildet und wobei der gesamte Randbereich auf einer Fläche des beweglichen Tastenteiles aufliegt und/oder wobei zumindest abschnittsweise die Abstände zwischen den Seitenflächen der Tastenkappe und die den Seitenflächen der Tastenkappe zugewandten Randbereichen der Tastenblende bei unbetätigter Taste geringer sind als bei betätigter Taste.

It is intended to provide a push-button switch capable of providing a comfortable and natural click touch. To achieve the purpose, the button turns downward about the point (S) which joins the buckling wall (3) to the base (4) on the back face (11) side. Accordingly, the pulling force on the buckling wall (3) does not occur when the button (2) is pressed. Consequently, a user needs less pressing force, and can feel a clear and quite natural click touch.

The present invention provides electronic equipment which can make a manipulation surface of a pushbutton accurately project through a button hole formed in a face panel and can prevent play of the pushbutton even when positioning accuracy of the button hole is poor. The electronic equipment is configured such that an outer button and an inner button are mounted in a state that the buttons are movable relative to each other and engaging projections formed on the outer button are respectively positioned to engaging holes formed in the face panel. Due to such a constitution, even when an axis of the button hole of the face panel and an axis of a guide portion of a chassis are displaced form each other, it is possible to make a manipulation surface of the outer button accurately project through the button hole and, at the same time, it is possible to prevent play of the outer button.

Upon depression of a depression surface (7) of an operating knob (6) of a switch assembly (1), a depression working surface (10) pushes down the head portion of a rubber contact (5), and a switching operation is performed. The operating knob (6) is pushed up by the return elastic force of the rubber contact and returned to its original position. Then the upper face of the depression portion (9) abuts against the correction member (4). As the correction member (4) is positioned directly above the rubber contact (5), the moment generated by the return elastic force of the rubber contact is offset and the operating knob is straightened and maintained to be in a horizontal position. Therefore, the side surfaces of the head portion (8) projecting from the operation hole (3) of the switch case barely rub against the side edges of the operation hole (3) in a depressed state owing to inclination of the operating knob.
