<p>The device is mounted on the cable control (1) of the fuel metering system of the engine, and includes mobile contacts (10) and (11) mounted on a contact-holding piece (28) solid with sheath (2), the mobile contacts (10, 11) working with stationary contacts (13) and (12) mounted on conductive tongues (15) and (14) placed in the upper part (16) of the switch. The contact-holding piece (28) is returned into position by a spring, which rests on the lower part (5) of the switch so that for a non-zero force on contact-holding piece (28) the circuit opens between contacts (11) and (12), and (10) and (13). The spring is calibrated so that the return force that it exerts, when the mobile unit of the contact-holding piece (28) comes against stop (22) of lower part (5) of the switch, is less than the force necessary to open the fuel metering system of the engine from its idle position.</p> |
