character which button should i push the red button

The push button switch generally consists of a button cap, a return spring, a bridge-type moving contact, a static contact, a pillar connecting rod and a shell.Īccording to the opening and closing state of the contacts when the push button switch is not subjected to external force (ie static), it is divided into start push button switch (normally open button), stop push button switch (normally closed button) and composite push button switch (NO and NCd contact combination buttons). The main parameters, type, mounting hole size, number of contacts and current capacity of the button switch are described in detail in the product manual. For example, red means stop button, green means start button, etc. Its colors are red, green, black, yellow, blue, white, etc. In order to indicate the function of each button and avoid misoperation, the button caps are usually made into different colors to show the difference, as shown in the figure below. When the button is pressed, the two pairs of contacts act simultaneously, the NC contact is disconnected, and the NO contact is closed. Each pair of contacts consists of a NO contact and a NC contact. Usually each push button switch has two pairs of contacts. The push button switch can complete basic controls such as start, stop, forward and reverse rotation, speed change and interlock.

Once the external force is removed, due to With the action of the spring, the switch returns to the initial position. Its characteristic is that it is installed in the machine and instrument in the process of work, most of the time is in the initial free state position, and only when needed, it is converted to the second state (position) under the action of external force. It is used in electrical automatic control circuits to manually send control signals to control contactors, relays, electromagnetic starters, etc. The push button switch is usually used to turn on and off the control circuit, and it is a kind of control switch appliance that is widely used. It is a very simple component, but because it controls the entire control circuit, it is called the 'Control switch'. We encounter various push button switches almost every day, such as medical equipment, automated production lines, and communication equipment.
