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:
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.
Button (button) is a commonly used control electrical component. It is a switch used to control certain functions of machinery or programs, or to turn on and off control circuits, so as to achieve the purpose of controlling the operation of motors or other electrical equipment. Generally speaking, the red button is used to stop a certain function, while the green button is to start a certain function.
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.
