The signal light indicator is a device used to communicate with other drivers. It provides information about the driver’s intention and helps others take appropriate action.
· Automotive turn signal lights
· Traffic lights
The first signal light car was introduced in the late 1800s, and they were used to indicate the direction of traffic. These days, they also show if a vehicle is turning left or right, has its hazard lights on, or indicates a right turn by flashing its right-hand indicator.
A big part of being a safe driver is being able to inform other motorists of your intentions. Signaling lights are both at the frontal and rear part of the vehicle and are sometimes also called “blinkers” and “signal light indicators.” Depending on the side you flicked on, your car will indicate whether you’re turning left or right.
The core of industrial control is the control of the motor, the core of the motor control is the contactor, the conventional component of the contactor coil control is the button switch, today we will take the button switch of GQELE Electric as an example, briefly introduce the function of the button switch in the second Function, use and installation in control loops.
Installation category
This series of buttons are φ22mm panel mounting buttons, and the panel mounting holes are φ22.7mm~φ22.3mm. Standard buttons can use 1~6mm thick mounting panels, and economical buttons can use 1~4mm thick mounting panels.
What is an emergency stop push button switch?
Emergency stop switch, also known as emergency stop switch, emergency switch, kill switch or emergency button, emergency stop button switch, is a fail-safe control switch that provides safety protection for machinery and equipment. People who use machines.
specify the following requirements: Emergency stop switches must be highly visible in colour, labeling and shape for easy operation in emergency situations. So the button has to be a red mushroom head with an arrow, emergency or stop symbol.
Common sizes for mushroom heads are 29mm, 30mm, 40mm or 60mm. The direct operating mechanism must be set on a normally closed contact and have a self-holding function. It requires a twist, pull or key to release the electrical contacts to allow the machine to restart.
Emergency Stop Button (E-stop for short) is an emergency stop device, usually used in mechanical and automation systems to prevent accidental injury or equipment damage. The following are the main functions and features of the emergency stop button in production:
effect:
Emergency stop: When a dangerous or unexpected event occurs, press the emergency stop button to stop the machine or equipment immediately to prevent further injury or equipment damage.
Convenient operation: The emergency stop button is usually located in an easily accessible position of the machine or equipment, and is generally easy to identify and operate.
System safety: By using the emergency stop button, it can reduce the negligence and error of the system operator and help ensure the safety of the system.
Protection equipment: the emergency stop button can automatically cut off the power supply in case of equipment overload, overheating, overvoltage, etc., so as to protect the equipment from damage.
characteristic:
Independent control: The emergency stop button is usually not related to the control of other equipment, and has an independent circuit to ensure that the machine or equipment can be stopped immediately under any circumstances.
Easy reset: Once the emergency stop button is pressed, it must be reset manually to restart the machine or equipment. This can prevent the machine or equipment from restarting in an unsafe state.
Reliability: The emergency stop button must be reliable, operable, and highly reliable and durable to ensure that it can work normally when needed.
Standardization: The color and shape of emergency stop button are generally standardized to facilitate identification and operation, and comply with relevant safety standards and regulations.
Start and stop button switch, generally used for start and stop. Generally, there are green, red, yellow and so on. We usually use the green button as start, the red button as stop, and the yellow button as jog.
In fact, their internal structure is the same.
See the start, pass, and reset in the first picture for the physical picture. The start and reset buttons are different from the pass button. The start and reset buttons are push button switches with indicator lights. The physical contact diagram is as follows:
