Abstract

PURPOSE:To make a spring for reversal, which still functions as a contact, composable in compact in size as compared with such a case as constituting these elements separately, by installing a moving armature spring whose intermediate part comes into contact with a receiver part and a contact part after being turned over, and one end is engaged with a notch and the other end is engaged with a lug. CONSTITUTION:A first terminal 13 projected inside and outside is installed in a bottom plate 12 of a case 11 made up in a nearly rectangular parallelepiped, and a notch 14 is installed in the inner part of this first terminal 13. A receiver part 15 is installed in the case 11 as projected out of the notch 14. A contact part 16 is installed there in opposition to the receiver part 15, a second terminal 17 is installed as one body with a contact part 16, and the second terminal 17 is projected to the outside from the bottom plate 12. A lug 19 is installed in the receiver part 15 and the contact part 16 at the opposite side to the notch 14 free of access motion from an upper plate 21 of the case 11. There is provided with a moving armature spring 26 in contact with the receiver part 15 between the receiver part 15 and the contact part 16, while one end of the moving armature spring 26 is engaged with the notch 14, and the other end is engaged with an upper angle in an engaging recess 23.
