PURPOSE: To provide an electromechanical device for sending a signal to a controlled electric device and displaying its condition, which is disassembled quickly and rationally during failure and reduces largely stress impressed on a printed circuit board by manufacturing errors. CONSTITUTION: An electromechanical device consists of a front subassembly which is fixed on a plate and has an unit interacting with an operator, a link fixing an electric module detachably on the unit, and a printed circuit board which is connected electrically to the electric module at one end and the controlled electric device at the other end. The module is fixed on the printed circuit board to form a back subassembly, two subassemblies are mechanically and detachably combined by the link, and the link is accessible through an orifice in the printed circuit board and is constituted, so that before subassemblies are firmly combined, the link allows a play between the unit and the module on a plane substantially parallel to the printed circuit board. |
