Abstract: An electromagnetic relay includes a fixed contact holder, a moving contact holder, an electromagnetic device, and a magnet. The fixed contact holder extends in a predetermined direction and is provided with a fixed contact. The moving contact holder also extends in the predetermined direction, and is provided with a moving contact. The magnet is arranged perpendicularly to an opening/closing direction of the fixed contact and the moving contact. A stretch space in which an arc generated between the fixed contact and the moving contact is stretched is provided, in the predetermined direction, beyond respective tips of the fixed contact holder and the moving contact holder. The stretch space also faces a surface of the fixed contact holder and a surface of the moving contact holder.

Abstract: A first end portion includes a first contact. A second end portion includes a second contact. At least a first end portion, out of the first end portion and a second end portion, is curved to be folded back from a tip in one direction of the first end portion. The first contact is located in a folded-back part of the first end portion and faces the second contact.

Abstract: An acceleration sensor includes a weight portion having a recess section and a solid section, beam portions, a movable electrode provided on the opposite surface of the weight portion from an open surface of the recess section to extend over the recess section and the solid section, a first fixed electrode arranged at the opposite side of the movable electrode from the recess section, and a second fixed electrode arranged at the opposite side of the movable electrode from the solid section. The acceleration sensor detects acceleration using a change in capacitance between the movable electrode and the fixed electrodes caused by rotation of the weight portion. The beam portions are shifted toward the recess section such that an angle between a perpendicular line extending from a gravity center position of the weight portion to the rotation axis and a surface of the movable electrode becomes equal to 45 degrees.
