摘要

An electrical contact device especially an electric vibrator with possibility of regulation of a body that this effect is associated with a frame part regulate strain whose particularity is that the frame part regulate cooperates with a second piece of deformable frame whose deformation determines the displacement of the part of said frame first and may further have the contact piece or the contact device the following features taken separately or as various combinations: a) the frame part carrying the electric organ and the frame part whose deformation determines the displacement of said piece of first frame are associated with each other. b) the frame part carrying the electric organ and the frame part which depression allows to regulate the fixed contact one conta abut each other c) the two frame parts have such dimensions that in regulating the frame part bearing the electric organ is subjected to an elastic deformation whilst the other frame part is a plastic deformation d) a displacement of the frame part carrying the electrical organ is determined by further displacement of the frame part which deformation determines the moving the part of said frame first: e) there adjustability magnet core which sends the moving contacts this core formed by a stud projecting from a plate frame and the frame part being the deformation of which determines a displacement of the frame part carrying the magnet core is constituted by the part of the plate bastid or which it is arranged behind the cleat and having a bore whose dimensioens relative to the plate material surrounding are such that a widening of the plate surrounding it are such that a widening of the aperture determines a displacement in the direction of the length of the block; f) a stationary contact mounted on its elásticaemnte termination on a flexible portion B of frame part A and precise regulation of the fixed contact becomes however possible abatement elsewhere (c) of the same part (A) ; g) the portion (B) carrying the fixed contact and the part (c) whose depression enables regulation of the fixed contact have the form of a tape or a sheet and not associated with each rather than one end to the frame part a; h) the tape-shaped parts (B and C) are parallel to one another and are associated on the same side of the part A; i) a fixed contact is fastened to a frame part (A) in one of its form above and part (B) carrying the fixed contact and qeu was originally in one plane with the workpiece A has been made in known manner to a deformation such that has been subjected to a displacement which can be considered as a superposition of a displacement in the plane and a displacement perpendicular plane of said part whilst the part (C) whose depression enables precise regulation and fixed contact was originally directly next to the part (B) has been subjected to a depression such that rests against the part (B); j) the fixed contact is fastened to a frame part in the form of tape near the two ends it has bores through which is fixed to rods insulation together with this part and other identical parts constitute the frame of the vibrator step the frame part as citna has on one side an extension which makes contact pin times.
