Abstract:
A remote controller for setting timer programming items wherein a display section is constructed in such manner that display items are provided in parallel with mechanical rotary switches, the distance between the rotary switches and their displays is adjacent and the relation between them becomes one to one correspondence, whereby an operator manipulates operational switches without making mistakes while looking at display items corresponding to the operational switches.
Abstract:
In a position detecting switch, a first movable contact is disposed in a first receptacle formed in a sliding body and is urged toward a casing member by a first spring so as to engage first and second stationary contacts mounted in the casing member when the sliding body is in a selected position. In order to prevent non-contact due to rotating moment of the first movable contact relative to the stationary contacts one or more features for inhibiting or reducing the relative moment are provided such as: (1) The first and second stationary contacts can be urged toward the first movable contact by fourth and fifth springs. (2) An elastic member or members can be disposed in a clearance between end walls of the sliding body and walls of the first receptacle. (3) The first spring can be restrained to apply its load to a substantially middle portion of the movable contact. (4) A plurality of the first springs can be provided to apply load the movable contact at a plurality of locations in a lengthwise direction. (5) An interval between the first and second stationary contacts can be increased. (6) An auxiliary receptacle member can be provided in the contact receptacle in the sliding body. (7) A lid can be disposed in the opening of the contact receptacle and have an opening larger than the movable contact but smaller than the contact receptacle.
Abstract:
A rotary switch having a terminal base molded on a lead frame which includes internal contacts and external terminals, along with the connecting straps between them, all formed of a single metal part. Portions of the metal of the lead frame are selectively removed in order to create a variety of switch configurations. Different switch actuating rotors are provided which further allow creation of different switch modes (single throw, double throw, etc.). The rotor is also provided with detents in order to allow for retention and indexing of the switch positions. A ramp may be selectively installed into the rotor to eliminate unwanted detent positions without requiring a different rotor. One or more "floating" movable contact elements complete the circuits when the rotor allows a respective spring to force a floating movable element into contact with both of a corresponding pair of stationary contacts of the terminal base. A separately usable illuminated indicator module is mounted on a bushing surrounding the switch rotor and the knob of the switch transmits light passing from the indicator module to the front of the knob where it can be viewed. The module includes a light distributor which directs the light from a single lamp to several positions corresponding to the switch positions.
Abstract:
A displacement detecting switch device is assembled with ultrasonic welding techniques, so that easiness of assembling work for it is further increased. The device comprises a switch body including a cover body and a base plate; an operation lever disposed pivotably outside of the switching body; and a movable plate disposed inside of the switch body and linked with the operation lever. There are disposed a first joint portion and a second joint portion formed by ultrasonic welding between the cover body and the base plate and between the operation lever and the movable plate, respectively.
Abstract:
An illuminated multi-position rotary selector/control switch assembly for switching substantial direct current (20 amps) at low voltages (12 V). A lower plastic housing shell is molded in a two-stage process with the first stage comprising molding platable thermoplastic resin strips and molding thereover second stage unplatable thermoplastic with exposed surface portions of said first first stage subsequently plated to form conductive strips having stationary switching contacts attached. The connector terminal pins are formed integrally with the strips in the first stage molding. The second stage thermoplastic molded thereover forms the part outline. The upper housing shell has a transparent arcuate window molded integrally therein for collecting and feeding light from a lamp to a light pipe carried by the user rotatable actuation knob.
Abstract:
A see-saw type illuminating switch apparatus having an illuminating portion provided on the upper surface of an operating portion, the apparatus having a light conduction body for conducting light of a light source, the light conduction body having a light issuing portion disposed in an oscillating direction of the operating portion under the operating portion, the operating portion being provided with a light conduction path leading to the upper surface thereof, the operating portion having a lower end formed into a forked configuration so as to ride on the light issuing portion.
Abstract:
A switch for detecting an erroneous erase protection fin provided on a side wall of a video tape cassette including a stationary contact strip made of electrically conductive metal, a movable contact strip made of electrically conductive metal, and a main body formed by an integral molding of electrically insurating synthetic resin. The main body includes a base portion for supporting the stationary and movable contact strips such that they are aligned in a direction in which they are resiliently deformable, a first actuation portion which is engaged with the stationary and movable contact strips, a first flexible portion provided between the base portion and the first actuation portion, a second actuation portion which is engaged with the movable contact portion, and a second flexible portion which is provided between the base portion and the second actuation portion. When the cassette has the fin, the first and second actuation portions are pushed and the stationary and movable contact strips are placed in contact with each other, but when the fin has been removed from the cassette, the second actuation portion is not pushed and the movable contact strip is separated from the stationary contact strip.
Abstract:
A joystick mechanism having a barrel rotator is capable of multiple axis movement and multiple axis analog signal control. The joystick mechanism can be selectively spring centered on two axes, spring centered on one axis and frictionally positioned on the other, or frictionally positioned on both axes. A pair of switch mechanisms, one for each axis of movement, selectably engage or disengage the respective centering spring mechanism. The analog signal generators are adjustable from the outside to provide biasing as required.
Abstract:
A multifunction human digit control includes a rotating cylinder journalled in a movable bar slidable in a groove in a deflectable support track. Rotation of the cylinder by a thumb or finger generates a first motion signal and movement of either or both of the bar and the cylinder by tactile movement, generates a second motion signal, representing, for example, X-axis and Y-axis positions, respectively, of a cursor on a computer screen. Various types of motion detectors or encoders are disclosed to detect the various movements of the bar and cylinder. The mechanism also permits actuation of a switch or other motion detector in a Z-axis by deflection of any one of the bar, the cylinder or portions of the support track with respect to a support structure. In a preferred embodiment, the overall control has its digit-operated tactile surfaces exposed in an aperture contained in a device casing, such as an opening in a computer keyboard or in an instrument housing or control panel.
Abstract:
A bistable switch for use, in particular, as a headlamp dipswitch on a motor vehicle, comprising a housing (100) which receives a control crosshead (200) guided in translation (O) between a rest position and a working position, a toggle bar (300) extending in the direction of crosshead displacement and being pivotally mounted to the crosshead about an axis (302) extending transversely to the direction of crosshead translation, a contact carriage (400) capable of moving in a direction (Q) generally perpendicular to the direction (O) of crosshead displacement and to the pivot axis (302) of the toggle bar (300), the carriage being provided with at least one contact stud (450) and with two camming slopes (460, 470) provided on a common face of the carriage facing the toggle bar (300) in such a manner that the camming slopes (460, 470) are placed alternately opposite the toggle bar (300) depending on the position of the carriage in the housing.
