ABSTRACT:
A probe for checking linear dimensions of mechanical parts comprises a support, a movable arm carrying a feeler adapted for contacting the part to be checked and an integral member coupled to the movable arm and the support. The member includes a first portion fixed to the movable arm a second portion fixed to the support and an intermediate portion having two sections with reduced thickness which define two axes of mutual rotation of the first and second portion. An electrical circuit closed under rest conditions comprises two pairs of electrical contacts which are opened in consequence of displacements of the movable arm along opposite directions or of an axial displacement of the arm.
