Elevator Door Lock Silver Contact Switch broadly refers to the intersection point of mutual separation and contact when the elevator electronic appliances are disconnected and closed. Since the metal conductor terminal is prone to generate instant heat and sparks at the moment of contact, the Silver Contact Point of elevator limit switch is In the multi-frequency process used, oxidation and electrolysis are prone to occur, so the Electrical Silver Contact Rivet of the elevator push button switches is enlarged and thickened, or it is made of polymer metal (mostly copper and silver). Therefore, the bussmann elevator disconnect Electric Contact made of polymer metal, or the Contact Rivet of eaton elevator control switch that is enlarged and thickened with the same material, is called the Silver Contact of the elevator switch button.
What are the elevator safety circuit switches?
Control panel emergency stop switch, phase sequence relay, thermal relay, speed limiter switch, upper limit switch, lower limit switch, etc. The elevator system must be equipped with a safety circuit which the key part is the Electrical Silver Contact. The safety circuit means that each safety component of the elevator is equipped with a safety switch . All safety switches are connected in series to control a Silver Alloy Electrical Contact safety relay. Only when all safety switches are connected, the safety relay Pull in, the elevator can run with electricity.
What are the common elevator safety switches?
1. Machine room: control panel emergency stop switch, phase sequence relay, thermal relay, speed limiter switch which made of the Silver electronic contact;
2. Well: upper limit switch, lower limit switch (some elevators put these two switches in the safety circuit, and some use these two switches to directly control the power supply);
3. Pit: broken rope protection switch, pit maintenance box emergency stop switch, buffer switch;
4. In the car: the emergency stop switch of the control box;
5. Car top: safety window switch, safety gear switch, emergency stop switch of car top inspection box.
What are the safety precautions for elevator use?
1. The elevator can not be overloaded. When an alarm occurs, it is necessary to voluntarily exit and wait until the next trip. It is very dangerous to know that the elevator is overloaded.
2. Do not block the elevator door. When the door is about to close, you must not rush in forcibly, let alone put one foot in the elevator and leave the other outside. Doing so is also very harmful.
3. Don't press the emergency button casually. This is set to deal with unexpected situations. During normal operation, you must not press it, or it will cause trouble.
4. When taking the elevator, if it starts to run before the door is closed, it means that there is a fault in this case. Do not take the elevator, but tell the maintenance personnel.
5. When a fire breaks out, stop the elevator on the floor where the smoke and fire have not yet spread. You cannot use the elevator to escape, and you should escape from the safety exit.
6. When a fault occurs, you must not panic at this time. You should press the walkie-talkie to notify the maintenance personnel to repair it. Don't press randomly. It is a wise choice to wait.
7. After the elevator has stopped, it is necessary to observe whether the floor of the elevator car is level with the floor. If it is not normal, it means that there is a fault in this case. The maintenance personnel must be called to overhaul to ensure the safety of passengers.
