Abstract: A switch that includes a hermetically sealed container including a container wall separating an inside of the hermetically sealed container from an outside of the hermetically sealed container, a magnetic sensor arranged in the hermetically sealed container and configured to be turned ON/OFF by a magnetic field of a magnet acting from the outside of the hermetically sealed container through the container wall of the hermetically sealed container, and a first magnetic body provided at the container wall of the hermetically sealed container and serving as a path of the magnetic field acting on the magnetic sensor from the magnet.

Abstract: A rotary connector including a stationary housing, a rotating housing and a lock member. When the lock member is mounted on the rotary connector, both housings are reliably locked with no free rotation therebetween permitted. The lock member is easily broken at a thin portion to release the locked state. A holder having a slot is integrally formed with the outer cylindrical portion of the stationary housing, while a projection is formed on the top surface of the rotating housing. The lock member is integrally formed of a horizontally extending arm portion, a ring-shaped finger-hook portion integrally connected to one end of the arm portion, and a coupling portion that extends downward from the other end of the arm portion. Formed on the border between the arm portion and the coupling portion is a V-shaped groove, as the thin portion, which is mechanically weaker than the rest of the lock member.

Abstract: Disclosed is a rotary connector mounting structure which involves no rattling after the mounting to thereby achieve a reduction in noise in spite of the adoption of a snap-in system, which allows the rotary connector to be easily mounted to the steering device of an automobile. A displacement absorbing member such as an elastic member 5 or a cushion member 13 is provided on the bottom surface of a first, stationary housing 1, and a mounting member 4 of the first housing 1 is snapped in on a switch casing 10 of a combination switch, which is the stationary member of a steering device. After this, the bottom surface of the stationary housing and the mounting surface of the stator member are biased by the displacement absorbing member such that they move away from each other, whereby rattling of the stationary housing is prevented.

Abstract: A vehicle lamp having inner and outer lenses and a reflector mirror surface. The inner lens is a Fresnel lens for converting light beams from a light source into parallel light beams, and the outer lens is an ordinary lens for obtaining a desired divergence property of the lamp. The reflector mirror may be a plane mirror, a mirror of a truncated cone shape, or a mirror of a parabolic cylinder shape. The Fresnel lens has as its focal point the virtual image of the light source as obtained by the reflector mirror, thus realizing a compact and small depth housing of the lamp while effectively using the light beams.
