Abstract: A plurality of vertical bends are provided in a terminal projecting from a switch contact outwardly of a case. With this structure, when the terminal is soldered to a land on a wiring board, a plurality of solder layers are formed between the plurality of bends and the land. The plurality of solder layers can enhance the terminal strength, thereby preventing the switch from coming or floating off from the wiring board. Thus, a switch capable of ensuring reliable operation can be provided.

Abstract: A spring member is provided in a switch having a lever to receive a pushing force from outside, by bringing an arch-part formed at the left end of the spring member into resilient contact with the bottom surface of the lever, in addition to the movable contact, the spring member also can return the lever. In the case of developing a compact and low-profile switch, the returning force of the lever can be increased to perform electrical connection or disconnection reliably.

Abstract: A switch device includes a wiring board having a cutout provided therein, a land provided on an upper surface of the wiring board around the cutout, and a switch. The switch includes a lever, a switch contact activated upon the lever being moved in a predetermined direction, a case including a step portion protruding from a surface thereof and positioned in the cutout of the wiring board, and a terminal protruding from the case and mounted on the land of the wiring board. The switch device securely holds the switch on the wiring board with a simple structure, and allows the switch to be activated reliably.

Abstract: An electronic component package tape comprising a carrier tape of belt-like form storing electronic components in storage pockets formed into a concaved box shape at predetermined pitches, a cover tape of ribbon-like form bonded to the carrier tape to seal upper openings of the storage pockets, and first protrusions, each having a tip of rounded surface formed on an underside surface of the cover tape facing the electronic components. The storage pockets may be provided with a second protrusion formed in an upwardly protruding manner on a bottom surface thereof. In a method of manufacturing the electronic component package tape, the cover tape is held between a first and a second rotating bodies. Both of the rotating bodies are rotated to form protrusions on the cover tape, which is bonded to an upper surface of the carrier tape in a manner to cover openings of the storage pockets.

Abstract: A lever switch includes a case, and a stationary contact, common contact, movable contact and lever which are disposed in the case. The movable contact is made up of elastic metal and includes a stationary portion, contact portion, and a curved portion located between the stationary portion and the contact portion. The stationary portion is connected to the common contact. The movable contact is disposed in a state of bending so that the contact portion may come in contact with or apart from the stationary contact. An operating portion is protruded from an opening, and a driving portion is located inside the case and abuts on the curved portion of the movable contact. When the operating portion is manipulated, the driving portion pushes the curved portion, and then the contact portion comes in contact with or apart from the stationary contact.

Abstract: The push switch of the invention includes: a case including a plurality of contact terminals placed on an inner bottom surface thereof and a contact member that includes a plurality of conductive protruding portions which come into contact with the plurality of contact terminals at selected positions while sliding on the inner bottom surface of the case; a fulcrum portion supported in a rotatable state by an axis parallel to the inner bottom surface of the case; and an elastic bent portion for connecting the protruding portions with the fulcrum portion. The push switch further includes a sliding body which is supported so as to move up and down along a direction vertical to the inner bottom surface of the case thereby pressing the contact member and sliding the conductive protruding portions in accordance with the vertical motion in order to switch the contact terminals between an electrical connection state and an electrical disconnection state.
