The self-locking switch is a common button switch. When the switch button is on for the first time, the switch is connected and held, that is, self-locking. When the switch button is on for the second time, the switch is disconnected and the switch button pops out at the same time. Self-locking switch generally refers to the switch with mechanical locking function, press down, let go of the button is not completely jump up, in a locked state, need to press again to unlock completely jump up, it is called self-locking switch. Most users do not know the difference between self-locking switch and self-reset switch in fact, the following misaki joint parts for you to brief!
First, what is the self-locking switch
1. Self-locking switch refers to the locking function of the switch that will not automatically spring up when it is pressed. The button will not spring up when it is pressed down and released. It's called a self-locking switch.
2. Self-locking both after power-on self-locking (itself will not disconnect), to other lines to disconnect it. A contactor is used to control a motor of higher power. The start button in the control circuit generally has no self-locking function, and it will spring up after being pressed down. Therefore, a group of normally open contacts in the contactor should be used and connected to the press button to do self-locking, also known as self-protection, so that the circuit can work normally.
3. Self-locking switch in positive and negative rotation and other multifunctional control circuit, self-locking can also prevent wrong action, to ensure the accuracy of the control circuit. In a normal circuit, a switch is pressed and the circuit is energized. Release the switch and the circuit breaks again. Once the switch is pressed, it can automatically maintain continuous power until it is disconnected by pressing other switches; Such a circuit is called a self-locking circuit.
4. Self-locking switch, that is, when you press it, it will be connected, until you press the second time, its latch will pop open, the principle is just like your oil pen.
Two, what is the self-reset switch
1. Self-reset switch, also can be understood as, since the compound key, press down to connect, you let go, it also follows the disconnect.
2. Automatic reset switch refers to the button press no matter to which travel position, will automatically return to the initial position, self-reset switch is more common, such as touch switch, straight Key Switch, Micro Switch, Toggle Switch and so on have a self-reset function, mostly used in hair dryer, rice cooker, computer boot key, induction cooker, refrigerator and so on. On the circuit is the understanding of the motherboard on the plug connection of one of the objects, hand press it short circuit, release and restore the open circuit, the short circuit will let the computer restart, simply said is a restart button.
3. The difference between the self-reset switch and the self-locking switch mainly lies in the mechanical and physical structure of the control of the internal travel. The self-locking usually has a card, and when the travel goes to the card, it will automatically lock. In fact, self - locking and self - reset is a structural function of the name, can cover all types of switches.
4. The price of the self-locking switch is mostly slightly more expensive than the reset switch, because on the design principle of the key structure, the internal working state of the self-locking relative to the reset, more structure, used to press the first time to lock the switch, disconnect the reset. For example, the intelligent luminous button switch in our common decoration furniture has self-locking and self-reset. The universal self-locking switch is used to control the fans and curtains in the room. However, self - reset is used more in the waterproof touch switch above.
