Claims (6)

1. A normally closed mechanical test relay designed to open the electrical circuit connecting the test object with a node or block, or the whole device, for a period of at least sufficient to evaluate the individual electrical parameters or characteristics of this object with the necessary accuracy, having at least one a switch containing at least a pair of mechanical electrical contacts, the first of which is configured to lead to said opening movement relative to the second the mechanical impact of the relay from the side of the object external to the test relay includes an external structural element that can be accessed from outside, the shape of which provides the required detachable connection of the test relay to the accessory of the measuring device while ensuring the relative position of the relay and accessory, for which the shape of the external structural element requires the presence of at least one protruding and / or in-depth fragment-stopper, available At least for the part of the designated accessory and intended to interface with the latter to form the desired connection, the first contact being made with the possibility of elastic deformation when it is moved under the action of mechanical stress exerted on this contact from the side of an external object directly or indirectly through another element or other elements of the test relay, despite the fact that this contact is configured to provide guaranteed closure of the test relay to restore its shape in the event of Avoiding mechanical impact from an external object. 2. The relay according to claim 1, characterized in that at least one fragment-stopper is made spring-loaded or elastically deformable. 3. The relay according to claim 2, characterized in that at least one fragment-stopper is located at a predetermined distance from the first contact, which allows, when the required connection is formed, to achieve the specified opening with a delay of at least the time of said fixation. 4. The relay according to claim 1, characterized in that the stopper fragment is either a toroidal, trapezoidal, rectangular or triangular protrusion, or a hole of arbitrary shape, or a groove, a pin, or a thread. 5. The relay according to claim 1, characterized in that it includes an electronic passive and / or active component, either a node or a block — an object of study. 6. The relay according to claim 5, characterized in that the object of study is located on the basis of the test relay.
