The button switch may be the simplest component in the electrical circuit, but it controls the lifeblood of the entire control circuit, so it is also called the "master switch". Understanding all kinds of button switches and using them skillfully and flexibly can make us get twice the result with half the effort.
Button switches are used to switch on or off small current circuits in a short period of time, and are mainly used in electrical control circuits. The current allowed to flow through the button switch is small, generally not more than 5A.
The button is generally composed of a button cap, a return spring, a bridge-type moving contact, a static contact, a pillar connecting rod, and a housing. The opening and closing state of the contacts when the button is not subjected to external force (that is, static), is divided into a stop button (that is, a dynamic break button), a start button (that is, a dynamic close button) and a reset button (that is, a combination of a dynamic close and a dynamic break. integrated button). When the button is under the action of external force, the opening and closing state of the contact changes: the normally open contact under static state is closed, and the normally closed contact under static state is open.
China push button manufacturers should have the following certifications in the European and American markets
push button CE certification: This is a mandatory certification for products sold in the European Economic Area (EEA) and indicates that the product meets EU safety, health, and environmental protection requirements.
RoHS certification: This certification indicates that the product does not contain any hazardous substances such as lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers.
UL certification: UL (Underwriters Laboratories) is a safety consulting and certification company that tests and certifies products for safety and compliance with industry standards in North America.
FCC certification: This certification is required for products that emit radio frequency energy, such as wireless devices, to ensure that they do not cause harmful interference to other devices.
ISO 9001 certification: This is a quality management system certification that indicates the manufacturer has implemented effective quality management processes to ensure consistent product quality and customer satisfaction.
IEC certification: This certification indicates that the manufacturer's products comply with international standards set by the International Electrotechnical Commission (IEC) for electrical and electronic products.
REACH compliance: This regulation restricts the use of certain hazardous chemicals in products sold in the EU and requires manufacturers to register and provide information on the chemicals used in their products.
Note: The specific certifications required may vary depending on the product and market.
A push button is a manually controlled master electrical appliance. It is mainly used to issue operation commands, turn on or off the control circuit, and control the operation of mechanical and electrical equipment. The working principle of the button is very simple. For the normally open contact, the circuit is disconnected before the button is pressed. After the button is pressed, the normally open contact is connected and the circuit is also connected; for the normally closed contact, Before the button is pressed, the contacts are closed, and when the button is pressed, the contacts are opened and the circuit is broken. Due to the needs of the work of the control circuit, a button can also have multiple pairs of contacts that act simultaneously.
Buttons have a wide range of uses, such as starting and stopping of lathes, forward rotation and reverse rotation, etc.; start, stop, rise, fall, forward, backward, left, right, slow or fast operation of tower cranes, etc., all need buttons control.
The push button switch refers to a switch that uses a button to push the transmission mechanism to make the moving contact and the static contact press on or off and realize the circuit switching. The push button switch is a kind of master electrical appliance with simple structure and wide application. In electrical automatic control circuits, it is used to manually send control signals to control contactors, relays, electromagnetic starters, etc.
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.
