A turn signal switch device capable of setting angles (release angles) in case a first lever member deviates from an outer peripheral face of a canceling projection and advances into a rotational locus at the time of right-turn operation and left-turn operation to the same angle is provided. A bent portion that is bent toward a rotational locus of a canceling projection is formed on the side of a free end of a first arm portion that protrudes linearly from a winding portion of a torsion coil spring, and when a distal end of a first lever member is dragged by the rotation of the canceling projection, and rotates in a direction away from the winding portion of the torsion coil spring, a resilient force is given to the first lever member from the bent portion of the first arm portion and a distal end on the side of the free end.

Turn signal switch device

A thin film magnetic head includes a recording and playback element, a lead conductor layer for feeding a power to the recording and playback element, an electrically conductive bump for conductively connecting the lead conductor layer to an electrode pad for external connection, and an insulating protective layer filling between the recording and playback element and the electrically conductive bump. A thermal deformation-preventing layer composed of a material having a thermal expansion coefficient smaller than that of the insulating protective layer is disposed in the insulating protective layer in such a way as to locate between a medium-facing surface and the electrically conductive bump without being exposed at the medium-facing surface. In the resulting thin film magnetic head, protrusion of the recording and playback element toward the recording medium side can be prevented without changing the configuration of the recording and playback element nor the forming material.

Switch stalk device

An in-vehicle knob switch device is provided. The in-vehicle know switch device includes a tubular housing having an opening and defined by a casing and a cover. A holder is disposed inside the housing. A circuit board is disposed on the holder. A first push switch is mounted on the circuit board. An operating knob is exposed through the opening of the housing and provided for pushing the first push switch.
