A connecting structure between a liquidizer switch and a circuit board comprises a liquidizer switch and a circuit. The liquidizer switch has a coupling end and the coupling end is defined with a slot. Plural conducting strips are arranged in the slot. The circuit board has a conducting end that is inserted into the slot of the liquidizer switch and contacts with the conducting strips. Thus, welding is not necessary at all, so as to save labor and improve assembly efficiency. On the other hand, the present structure can prevent the circuit board from being damaged because of high temperature produced during welding.

An electrical switching element comprising a housing having an elongated base. An electrical coil is wrapped around a yoke and arranged in the housing such that a center axis of the electrical coil is positioned parallel to the elongated base of the housing. An armature having a first switching contact is mounted in a sprung manner and in operative connection with the armature. A first low-profile contact is connected to the first switching contact, and a second low-profile contact is connected to the second switching contact.

A connector rail includes a full profile which is provided with first bearing surfaces and second bearing surfaces which are used to provide support in the window opening of the rear wall of the housing. The second bearing surfaces are provided with projections for securing continuous current conductors which are aligned in a parallel manner and which are, for instance in the case of low voltage circuit breakers, embodied as male contacts for fixed contacts. Respectively corresponding projections are provided in order to secure the flexible cables to the moveable switching contacts or to secure the fixed switching contacts.

A removable quick connect terminal for an electric power switch has a molded housing with an open cavity and an electrically conductive terminal member with a plurality of male terminations that project through slots in a cavity wall in the housing into the open cavity. The terminal member has a tang projecting outward from the housing that is clamped by a conventional collar terminal to a power conductor of the switch projecting into an external terminal recess in the molded switch casing. The terminal member is secured to the molded housing by a pair of oppositely facing chamfered catches engaging an opening in the flat center section of the terminal member. The molded housing of the quick connect terminal has hooks which engage abutment surfaces on the switch casing and a pair of integral compliant latches which engage latch ledges in the external terminal recess to removably secure the housing to the switch casing.

A control unit incorporating a pressure sensor has a case body with an upper opening, incorporating a printed circuit board on which a pressure sensor and a plurality of control circuit components are mounted, and a lid to close the case body. A connector box extending outward is attached to one sidewall of the case body. The pressure sensor is disposed in the vicinity of the connector box. A first pressure passage is integrally formed with the lid, being opposed to the pressure sensor. A second pressure passage communicating with the first pressure passage is integrally formed with the lid, extending in the same direction as the connector box.

The present invention includes a new dome contact construction having an integral insulative layer that is precisely cut and aligned with the dome contact mechanism during fabrication. Prior to feeding the metal sheets or strips into the equipment for stamping and cutting the dome contact using the conventional method, a die cut layer of film is applied to one side of the sheet or strip. The film is cut into the shape of the desired insulative layer in the finished switch product and has periodic openings that correspond to the areas of the dome contact that are required to be uncovered both to provide electrical conductivity as a part of the proper function of the switch. The sheet of metal, including the laminate film, is cooled to a temperature near freezing to facilitate clean stamping of the laminated feedstock during the stamping process and is then fed into the forming and cutting press where the domes are formed and stamped.
摘要:
A diaphragm touchbutton switch having a housing and a touchbutton slidingly guided on the housing. The housing comprises an outer wall that extends to a base surface area facing away from the touchbutton. The outer wall is bent inwards at the base surface area and passes into an inner wall angled parallel to the outer wall. The inner wall forms a connector chamber, and the touchbutton comprises at least one integrally molded guiding wall, engaged between the inner wall and the outer wall of the housing.

A protective device for minimizing fire danger in the use of electrical circuits comprises a unit having a mechanically biased conductive element in series with the circuit, and maintained in position under tension by a fusible material such as a Cerro alloy having a yield point at a selected temperature threshold. When overheating at some other point in the circuit results rise of temperature at the protective device, the yielding of the fusible material allows the conductive element to spring free, opening the circuit and cutting off the current. This arrangement is useful in an male plug integral to or separate from an extension cord, in conjunction with circuit breaker systems, in a in-circuit device, and in electrical appliances and devices.
