摘要:
An electronic timepiece assembly interposed between a module and an exteriorly operable member and comprising a switch lower base including a plurality of electrically conductive portions connected to a contact pattern formed on the module and a switch upper plate including a plurality of terminal portions formed in correspondence with the conductive portions and a plurality of projections operable by means of the exteriorly operable member so as to be resiliently deformed and connect the terminal portions through the electrically conductive portions to the contact pattern formed on the module.
摘要:
A push-button switch wherein a spring loaded plunger (22) is carried by a push-button operator (4) along a surface of a rocking contactor (20) across the plane of the support contact (16) for the contactor (20) to rock that contactor into and out of engagement with stationary contacts (12, 14). A U-shaped conductive bearing (18) is mounted over the end of the support contact (16) to provide a uniformly smooth pivot and current transfer surface for the contactor (20). The plunger (22) and spring (24) are loaded in a through-hole (4f) in the operator (4) wherein the spring (24) may be compressed just prior to final assembly into a switch housing (2), facilitating assembly operations for the switch.
摘要:
A distributor containing an apparatus for suppressing noise is disclosed. The distributor is comprised of a rotor, a plurality of stationary terminals and a hollow insulating member which is introduced into a discharging air gap formed between a discharging electrode of the rotor and each of discharging electrodes of the stationary terminals. The hollow insulating member has an arc-shaped discharging portion at one open end thereof, the other open end thereof is connected to the discharging electrode of the rotor. Thereby, a spark discharge, occurring between the discharging electrodes of the rotor and each said stationary terminal, is generated via a through hole formed inside the hollow insulating member and the arc-shaped discharging portion.

An Electric Dispatcher switching system is actuated by an electric clock mechanism and is designed to set in motion automatically, either simultaneously or consecutively, and to stop in the same way, a number of electric appliances or machines. The Electric Dispatcher comprises concentric circles of connecting structure energized by the rotating commutator arm of an electric clock having permanent magnets or gliders fixed on the commutator arm. Electric current is distributed through the connector structure to an electric wire system connected to technical equipment of a factory or institution in conformity with a time table previously dialed on a sectorized dial plate of the Electric Dispatcher.
摘要:
A switching device, notably for the control of an electrical motor in an air conditioning or ventilation installation of a vehicle, wherein a rotary knob carrying a slider contact is mounted on a small column of the bottom of a cage, and a circuit plate is mounted on the end of the column and immobilized by snap-in engagement with walls of the cage. The cage is adapted to be fixed in a casing or support provided in an instrument board of the vehicle.
摘要:
A combination selector and directional switch for electrically operated remote control rearview mirrors in which a single control fixture allows the operator to select a right or left hand mirror and then by manipulation of a pendant, movable in two plane directions, to orient the mirror glass as desired. The linear movement of a selector lever causes rotational movement of a selector ring whereby the left or right hand mirror is connected to be controlled by the selected manipulation of the pendant.
摘要:
A rotor formed with an integral hold down spring for use in a high voltage distributor to maintain a predetermined height in the commutation cavity.
摘要:
An electrical current transfer assembly includes a slip ring and a brush ring having an annular array of contact elements engaging the slip ring as one ring rotates with respect to the other, the brush ring being divided into a plurality of equal sectors each carrying a group of the contact elements, the contact elements being interlaced with respect to length among the plurality of groups to provide a distributed balanced engagement of the contact elements with the slip ring.
摘要:
An improved four-way switch operated by a single manual push button at the end of a control column includes an axially extending shaft mounted to pivot on a stud. The shaft and stud are retained within a housing. An elastomeric washer with a frusto-conically shaped center passage is affixed on the shaft and engages the housing to radially bias the shaft and thereby maintain the shaft in proper axial alignment. Contacts are attached to the shaft and engage selected contacts on the housing when the shaft is pivoted. Guide slots in the housing cooperate with the pivotal shaft to control the direction of pivotal movement of the shaft.
摘要:
A distributor for distributing a high voltage from an ignition system of an internal combustion engine to sparking plugs arranged so as to oppose to the rotating electrode through very small gaps is improved by the provision of a filmy layer made of an oxide of an alkaline-earth metal which is formed on the discharge portion of the rotating electrode or the surface of each of the fixed electrodes.
