Safety locks Each electric device in the car requires only the certain, precisely established quantity of a current. According to this consumption of a current in the given electric chain, naturally, the cross-section section of its wire has been defined. If current consumption increases in this electric chain, for example, at the expense of the consumer connected in addition or as a result of short circuit the wire is overloaded. Thus the wire is warmed up or even is heated, if current giving in time is not interrupted. It is done by safety locks. Replacement of safety locks
Additional safety locks At the certain expanded complete set on a 8-seater support of additional relays at the left under a control panel auxiliary safety locks take places. Thus it is a question of so-called thermosafety locks more often. These are safety locks which at an overload of an electric chain for a certain time interrupt a current stream, and then again restore connection. Inside (3) left face parties of a control panel in a clip are in facing small plastic nippers (2) to take out safety locks, and a crank (4) for an emergency control a sliding roof. In drawing placing of safety locks in a box (1) is below shown.
