Abstract

Particularly compact, removable bellows-type timing device for electric contacts whose closing or opening can be delayed. This timing device comprises a movable contact-holder pivotally mounted on two pivots disposed on the internal surface of the shell of the device, on either side of the bellows, the shape of the holder, ring or fork, being such that it surrounds at least partially the bellows when the latter is in expanded configuration: as a result, the dimension of the device, parallel to the direction of displacement of ghe bellows, is reduced.
