ABSTRACT:
A probe for checking linear dimensions comprising an arm movable along two opposite directions with respect to a support, a pair of electrical contacts fixed with respect to the support and a pair of flexible laminae having first ends connected to the movable arm and carrying at second ends a pair of movable electrical contacts, which--in rest conditions--are closed against a relevant one of the fixed contacts. An element fixed to the movable arm is adapted to cooperate with two surfaces coupled to the laminae next to the movable contacts, for causing, upon displacements of the movable arm from a rest position, release of either of the movable contacts from the corresponding fixed contact.
