Abstract: In the switch, a terminal section and a contact section of a fixed contact are separately formed and the two sections are connected via a coil made of a conductive metal wire. After electrical connection is established between a movable contact and fixed contacts, a weak current with no arc discharge flows between the movable and the fixed contacts. This prevents build-up of oxide or carbide on the contact surface, allowing the switch to have stable contact operation and accordingly reliable electrical connection.

Abstract: A groove-like recess, substantially V-shaped, extending vertically is formed on the outer circumference of an operation shaft, and a projection engaging the recess is provided on a guide hole, namely the inner circumference of a hollow pipe. Such makeup provides an automotive push switch that reduces an impactive force caused when the recess hits the projection within the movable range of the operation shaft, by decomposing or dispersing the force according to the inclination angle of the slope, and so does the hitting sound.

Abstract: The push-type vehicle switch has a case, an actuator, a movable contact, and a cap made of elastic material. The case has an opening and a fixed contact implanted inside thereof. The actuator is contained in the case reciprocably. The movable contact is provided facing the fixed contact and connects to and disconnects from the fixed contact according to reciprocable movement of the actuator. The cap covers the opening of the case.

Abstract: A switch for a vehicle used to control the on-off operation of a stop lamp for an automobile ensures electrical contact and separation with a simple structure.

Abstract: A switch provided with a fixed contact and a movable contact coming into contact with each other and separating from each other. The surface of at least one of the fixed contact and the movable contact is provided with a plurality of recesses whose edges are overlapped with each other, and also provided with a plurality of projections. The projections formed on the contact surface have sharp-pointed tips which can break an oxide film or the like if it is formed on the contact surface, thereby achieving stable contact.

Abstract: A knob section includes an elastic pawl protruding downward and contacting an outer surface of a light guide unit at an inner surface of the pawl. A holder includes a holding section contacting an outer surface of the elastic pawl. An illumination knob is provided by latching a recess of the elastic pawl to a protrusion of the holding section. The elastic pawl is sandwiched between an outer surface of the light guide unit and the holding section, thus allowing constituent components of the illumination knob to be held securely.

Abstract: A vehicle switch is capable of properly switching on/off electrical connection between fixed contacts. The fixed contacts of the switch are oppositely disposed on a substrate so as to be parallel to a moving direction of a moveable piece. A barrier constituted by a dent or a projection is disposed between the fixed contacts to increase the creeping distance between the fixed contacts. With such a simple structure, the vehicle switch can suppress degradation of insulation characteristics between the fixed contacts, whereby the electrical connections between the fixed contacts are properly established or cut-off.

Abstract: To provide a rotation angle detector with high detecting accuracy for use in association with a steering wheel on a vehicle and the like, a rotation angle detector is constructed by providing a recess surrounding a shaft portion in a top face of a detecting member, and extending a shaft support, formed on an upper cover, into the recess.

Abstract: A rotation angle detector includes a rotor, first and second detecting elements which rotate according to a rotation of the rotor, first and second detecting units for detecting rotations of the first and second detecting elements, respectively, and a control unit for detecting a rotation angle of the rotor based on a first signal when a difference between the first and second signals output from the first and second detecting units ranges within a predetermined range.

Abstract: An angle sensor can be re-mounted properly. This angle sensor includes a detecting sensor that detects a turned volume of a rotary shaft, and a governor connected to the detecting sensor. The governor includes a comparator that compares a turned angle data obtained before the angle sensor is detached with a turned angle data obtained after the angle sensor is re-mounted. This angle sensor produces a remarkable advantage when it is used in cars which are governed using the data about a turned volume of the steering wheel or the shaft.

The tactile feedback member is urged by the resilient member and brought into contact with a recess provided in the lower case.

Abstract: A rotational angle detector detects, with a detecting unit, a rotation of a rotary body rotating in cooperation with a steering wheel as a detection signal having a cyclic waveform that gradually increases or decreases in one cycle, calculates the detection signal as a rotational angle of the rotary body, and stores the detection signal. The rotational angle detector is used for detecting the rotational angle of a steering wheel of a car and allows the angle detection at a high solution in a simple structure.
