Abstract: A heart cam mechanism of a switch includes a cam groove, which includes a heart cam and surrounding cams, and a lock pin. The heart cam has a concave part, a first vertex opposite the concave part, and second and third vertices on a concave-part side. While the switch is in a locked state, an upper end part of the lock pin is engaged with the concave part of the heart cam, and is positioned at a locking position. While the switch is pressed, the upper end part slides while pushing against a bottom surface of the cam groove located outside the heart cam, and moves along a heart-shaped path, which is depressed at the locking position. This configuration prevents an end part of the lock pin from moving in a reverse direction even when a step-like part of the bottom surface of the cam groove is worn out.

Abstract: This invention provides a switch including a housing, a plunger that slides in a press direction or a return direction with respect to the housing, a return spring that biases the plunger in the return direction and is compressed by a slide of the plunger in the press direction, a plurality of terminals that are brought into a conductive state according to a predetermined position of the plunger, and a terminal contact spring that makes contact with the terminals so as to bring the terminals into a conductive state by the slide of the plunger in the press direction. The terminal contact spring is disposed so as to be compressed according to the slide of the plunger in the press direction under a contact state of making contact with the terminals.

Abstract: A switch and an electronic device maintain a power supply ON state until data processing is completed, and automatically turn OFF the power supply after the data processing is completed. The switch includes a rotation operating body that does not receive an operation force from an operating element when OFF operated is arranged inside the operating element. The rotation operating body includes a switch operating portion for turning ON a power supply switch mechanism and a return spring regulating piece for biasing a return spring in an anti-biasing direction. A regulating state of the return spring regulated by the return spring regulating piece is held, where the ON state of the power supply switch mechanism is held with a permanent magnet, and the ON state of the power supply switch mechanism is released by applying a release force on the permanent magnet when the power supply is reset.

Abstract: A switch has a supporting terminal assembled to a base, a movable contact piece, made of a band-shaped conductive material bent to a substantially J-shaped cross section, having a movable contact at one end and having an intermediate portion rotatably supported by a rotation receiving portion of the supporting terminal, a plunger accommodated so as to be movable up and down in an internal space formed by fitting a housing to the base, and a coil spring including a forced dissociation bent portion at one end and being rotatably supported by the plunger. The plunger is moved up and down to slidably move one end of the coil spring while pressure contacting the other end edge of the movable contact piece to invert the movable contact piece and contact or separate the movable contact to and from a fixed contact, and to lock a distal end of the forced dissociation bent portion to the other end edge of the movable contact piece and exert a shear force on the movable contact of the movable contact piece.

Abstract: In fabricating a door switch for a microwave oven, two switches are incorporated in a single switch case to allow a reduction in the size and to allow common use of switch components, thereby achieving a cost reduction through a reduction in the number of components. Further, a contact switching structure tilted in conjunction with opening and closing of a door is provided to achieve high accuracy in switching the switches. There is provided a first switch whose contact portions are switched by elastically displacing a conductive contact piece in the switch case when a first tilting lever is tilted, a second switch whose contact portions are switched by elastically displacing another conductive contact piece in the switch case at timing that is slightly different from the timing for switching the contact portions of the first switch, and a third switch which is switched when a second tilting lever is tilted.
