Abstract: Fit structure of a housing formed of first and second halves is provided. The first half has a fit projection piece having a fit tongue at the tip. The second half has a presser part and an engaging piece constituting a fit groove. The fit projection piece, presser part and engaging piece are formed so that the fit tongue is positioned in the inner part of the fit groove along the root of the presser part. The housing further has a nail stuck out in an inward or outward direction of the housing and a nail holder engaged with the nail. The nail and nail holder are located at one and the other of a part of the fit projection piece and a corresponding part of the engaging piece. The part of the fit projection piece is nearer to the root of the fit projection piece than the fit tongue.

Abstract: A sealed receptacle includes a case, a cylindrical member, and a closure plate. The sealed receptacle is configured to house a fixed contact, a movable contact, and an arc protection member. The arc protection member includes a peripheral wall, and a bottom. The peripheral wall is configured to conceal a junction between the case and the cylindrical member from the fixed contact and the movable contact. The bottom is interposed between the movable contact and the closure plate. The sealed receptacle houses a contact pressure provision member configured to bias the movable contact to come into contact with the fixed contact. The contact pressure provision member is interposed between the movable contact and the bottom so as to come into resilient contact with both the movable contact and the bottom irrespective of a position of the movable contact.

Abstract: This electromagnetic switching device comprises an electromagnetic device 1 in which a movable core 15 comes into contact with or separates from a fixed core 14 in response to energization of an excitation coil 11 wound around a coil bobbin 10 a contact device 2 with a fixed contact 21 and a movable contact which comes into contact with or separates from the fixed contact in conjunction with a movement of the movable core 15 of the electromagnetic device, and a boxy case 3 configured to house the electromagnetic device and the contact device.

Abstract: A contact device including a pair of fixed terminals 2 with a fixed contact 2a each, a movable armature 3 with movable contacts 3a which contact to or separate from the fixed contacts 2a, a movable shaft 4 connected to the movable armature 3 at its one end, a movable core 8 secured to the opposite end 4b side of the movable shaft 4, a movable core receiver 7 slid onto the movable shaft 4 so that it faces a surface 8b on the movable armature side of the movable core 3 to receive the movable core 8 driven by an electromagnetic mechanism, an impact absorber 17 disposed on a surface 7a on the movable armature side of the movable core receiver 7 to absorb an impact generated when the movable core 3 hit the movable core receiver 7, and a stopper 16 (a movement restriction member) disposed on a surface on the movable armature side of the impact absorber 17 to restrict a movement of the impact absorber 17.
