Today, we're going to talk about the most basic switch in the electrical sequence!
I'm going to post what I know here while organizing it, so please take a look
Before we explain the switch, we need to know about the contact points first.
The contact point is how to connect the wires to the wires.
Contact Type:
- Contact point A: The contact point is always separated, and when the switch is pressed, the contact point sticks.
- Contact B: The contact is always attached, and when you press the switch, the contact falls.
If contact A is used, electricity is energized as soon as the switch is pressed, and electricity is cut off when the switch is removed.
If contact B is used, if the switch is not pressed, electricity is energized, and if the switch is pressed, electricity is cut off.
Press Switch::
Say push switch or push switch.
This switch has both A and B points, and is usually the most commonly used switch in electrical sequences.
The push switch has a total of four ports.
Looking at the internal structure, the top two ports are contact B, and the bottom two ports are contact A.
The press switch has a spring attached to it, so it returns to its original state when pressed.
If the push switch is not pressed as in the internal structure, the two ports on the top are energized, and if the switch is pressed, the ports are energized on the two below.
toggle switch::
The toggle switch has three ports. It is different from the press switch, and there is a port called COM, so contact A and contact B power ports are used together.
If you look at the internal structure of the toggle switch, one wire enters the COM and connects another wire to A or B to move the lever to energize the wire.
The toggle switch has a two- or three-speed switch.
The two-stage switch can only be connected to point A and point B.
The three-speed switch can be connected by contact points A, NONE, and B.
The toggle switch used may be changed according to the circuit diagram. This content will be covered again later when analyzing the circuit diagram.
Emergency switch::
The structure of the emergency switch is the same as the press switch. But there is something different from a push switch. The emergency switch does not automatically return when pressed. You have to manually return it.
It means an emergency switch EMERGENCY, a switch that should be used in dangerous situations. Therefore, all processes must stop as soon as the emergency switch is pressed, and the emergency switch does not return because all emergency situations must be completed and the process must be carried out.
Emergency switches also have contact A, contact B, like press switches, and are usually used by connecting wires to contact A when there is an emergency to contact B during normal operation.
Finish::
We've learned about the switch and the contact point.
I want to deliver the knowledge I know easily and quickly, but it's not easy. Haha
Next time, I will try to write more easily. LOL
Thank you.
