Momentary switch automatic reset button switch is a kind of automatic reset switch, which includes a bottom shell and a button.
In terms of the reset method of the Momentary switch button, there are unilateral resets, bilateral reset, multilateral reset and vertical reset.
A momentary switch generally adopts a water accumulation structure, which is composed of a button cap, a return spring, a static contact, a moving contact and a shell, etc. It is usually made into a composite type, with a pair of normally closed contacts and normally open contacts, and in some products The number of contact pairs can be increased by connecting multiple elements in series.
There is also a self-holding button, which automatically maintains the closed position after being pressed, and can only be opened after the power is cut off.
When the button is not pressed, the moving contact is connected to the static contact above, and this pair of contacts is called a normally closed contact.
At this time, the moving contact is disconnected from the static contact below. This pair of contacts is called the normally open contact: press the button, the normally closed contact is disconnected, and the normally open contact is closed; release the button, The original working state is restored under the action of the return spring.
The difference between Momentary switch and other switches
The reset switch is simply a switch that can automatically reset. The reset switch can be cylindrical or square. In terms of appearance, it is no different from ordinary switches, but it is different in function.
The difference between the reset switch and the self-locking switch: After the reset switch is pressed, the initial state will be restored when the hand is released; after the self-locking switch is pressed, the hand will not return.
The reset switch is very similar to the jog switch. Strictly speaking, it is also a kind of jog switch, but the difference between the reset switch and the ordinary jog switch is that the selection of the reset switch is longer, and the contact is not a point, but a stroke
What is the function of the momentary switch with key reset in the security
The main purpose is to ensure that the relevant person in charge comes to the scene in person. The purpose is not to reset, but to let the person in charge check the on-site alarm situation and confirm the situation.
Use and maintenance
(1) Check the button frequently to remove the dirt on it. Due to the small distance between the contacts of the button, after many years of use or the seal is not good, the inflow of dust or various stages of engine oil emulsion will cause the insulation to be reduced or even a short circuit accident.
In this case, insulation and cleaning must be done, and corresponding sealing measures must be taken.
(2) When the button is used in a high-temperature environment, it is easy to deform and age the plastic, causing the button to loosen, causing a short circuit between the terminal screws.
According to the situation, a fastening ring can be added to tighten it for use during installation, or an insulating plastic tube can be added to the wiring screw to prevent loosening.
(3) For the button with indicator light, the bulb will heat up, and the plastic lampshade will be deformed for a long time, which will make it difficult to replace the bulb. Therefore, it is not suitable to be used in places where the power is on for a long time; if you want to use it, you can appropriately lower the bulb voltage to extend its life.
(4) If poor contact is found, the reason should be found out: if the contact surface is damaged, it can be repaired with a fine file;
If there is dirt or soot on the contact surface, wipe it with a clean cotton cloth dipped in a solvent; if the contact spring fails, it should be replaced;
If the contacts are severely burned, the product should be replaced.
