Abstract: A first stationary contact is provided on the base body. A second stationary contact is provided on the base body. A conductive click spring is disposed over the first stationary contact and the second stationary contact, so as to be always electrically connected to the first stationary contact and so as to be away from the second stationary contact in a neutral position thereof. A push button includes a head portion which is depressed by an operator, and an actuator which pushes the click spring so as to be abutted against the second stationary contact when the head portion is depressed. The head portion and the actuator is integrally formed from rubber having elastic restorability.

Abstract: The present invention has as its object to provide a push switch utilizing a click spring with superior electrical conduction during operation of the switch. The push switch 20 of the present invention has a fixed contact 4, and a spherical click spring that contacts the fixed contact 4 and acts as a traveling contact, the click spring 10 having a projection 11a that projects upward from a central part of the click spring 10, and further, an aperture part 11 formed inside the projection so as to be open at the bottom. When the projection 11a is pressed downward the bottom edge 11b of the aperture part and the fixed contact 4 form a line contact (see FIG. 2).

Abstract: A membrane switch fixes click springs at fixed positions and largely reduces the damage caused by dust and moisture affecting contact points. The membrane switch includes fixed contact points on a circuit board made from a film of resin material such as polyester. A movable contact point member is made of semi-spherical metal click spring touching the contact points. An insulation sheet is adhered to the circuit board including the click spring, characterized by a continuous air path connected to a portion of the click spring, which is formed as a portion where no adhesive material is placed, between the insulating sheet adhered to the top face of the click spring. The continuous air path is connected to the openings formed between an edge of the insulation sheet and an edge of the circuit board.

Abstract: To improve the affinity between a gas and a liquid, the liquid is passed through an enclosure where it contacts a portion of the magnets of a magnetic field generating device and passes through the magnetic field created by the magnets while a gas is in contact with the other portion of the magnets. A liquid level control device maintains and controls the liquid level so that the magnets simultaneously extend about equally into the gas and liquid with both contacting the magnets and being within the magnetic field created by the magnets. The gas in the enclosure increases the effectiveness that the magnetic field and magnets have on the liquid. The gas used in the enclosure can optionally subsequently be mixed with the liquid or another gas can be mixed with the liquid. Additional gases and liquids can be mixed together. The device and process associated with it can be used on different liquids and different gasses, including fuel mixed with air in a combustion process.
