The proposed device for measuring the force generating by a pressing element contains a casing, a lever with unequal arms, which is installed at a shaft that is fixed to the casing, a contact system, which contains movable contacts and fixed contacts, and indicating light-emitting diodes. The tip of the short arm of the lever contacts a stop provided at the pressing element. The long arm of lever is coupled with the casing by a spring and a link made of conductive material. The link is coupled with the spring and the lever by insulators and electrically connected to the negative terminal of the power-supply source via a button switch. The movable contacts of the contact system are arranged at the link. The fixed contacts are arranged at the casing. The cathodes of the light-emitting diodes are connected with the corresponding fixed contacts, and the anodes are connected to the positive terminal of the power-supply source.
