The push button switch is actually a device that requires people to manually send various signals to control the circuit or device. It is mainly used to push the transmission mechanism through the button to achieve the switch that turns the static and electric shock on and off. Generally, the basic start and stop, Variable speed and so on can be controlled by it. A push button switch has two pairs of electric shocks, each pair consists of a normally open and normally closed electric shock. When pressed, two pairs of electric shocks will simultaneously emit motion, normally closed contacts. Disconnected, normally open contact closed.
The push button switch is generally used in various electrical automatic control circuits. People can manually control the various contactors, relays, electromagnetic starters, etc., and everyone must decide according to the environment used.
If you need to purchase, you must first determine its use environment and use, such as embedded in the operation panel, this can be selected to open, and some need to display the working state of the device, then you need to select the cursor However, there are occasions where it is easy to operate incorrectly, which is suitable for the key-operated push button switch.
Those who have seen the button switch should know that its button color is different, the most common ones are red, black, white, green, etc., green can be used as the start button, emergency stop button needs to use red, stop button can In black, gray or white, depending on the requirements of different circuits, you need to determine the number of button switches you need. Common ones are single button, double button and triple button.
It should be noted that the installation and use of the push button switch must be ensured to be safe and reliable, that is, it must be checked repeatedly during installation, whether the wiring is reliable or not. If the push button switch needs to be placed in a high temperature environment, it is easy to be deformed and loosened. In this case, an insulating plastic tube is placed on the terminal screw to prevent a short circuit.
