A weight with optimum weight and high strength can be easily manufactured and the vibration actuator with excellent vibration characteristic is provided. The vibration actuator is formed by a casingwith cylindrical shape, a coilprovided in the casing, and a moverthat vibrates along an vibration-axis direction of the casing. The moverincludes a mover body and a weight fixed to the mover body. A protrusionprotruding toward an opening of the casingis provided at a central portion of the mover body, and a recesswhich is recessed toward the opening of the casingis provided at the central portion of the weight. The mover body and the weightis fixed in a state in which the protrusionis inserted into the recess

Oscillatory actuator

A vibration actuator that can prevent reduction of vibration performance and durability of the vibration actuator and that can prevent occurrence of operation failure and noise when the vibration actuator had impact from the outside is provided. The vibration actuator includes a cylindrical casing having a first coil and a second coil, a movable element arranged inside the casing and having a magnet, and a first inner guide and a second inner guide arranged between the first coil and the second coil, and the movable elementand having extending portions and which sandwich and hold a part of the first coil and the second coil together with the casing.

Vibration actuator

An oscillatory actuatorincludes a cylindrical case, an electromagnetic driver, a mover, a first damper, and an inner guide. The electromagnetic driveris provided inside the case. The moveris enabled to oscillate through driving by the electromagnetic driver. The first damperhas a plurality of armssupporting the moverfrom an inner surface of the case. The inner guideis provided on the inner surface of the caseand restricts movement of the first damperbeyond a predetermined range. The inner guideis located further toward a center of the casethan the first damperin a direction of an oscillation axis ◯ of the mover

A cable switch comprising a first base member of a band shape provided with a conductor on an inner surface and a second base member facing the first base member, and including a flat positive electrode and a negative electrode, the positive electrode being provided on one side of an inner surface thereof and the negative electrode being provided on another side of the inner surface, a gap being formed between the positive electrode and the negative electrode for separating and insulating the positive electrode and the negative electrode from each other.
