On some relatively large equipment, the size of the small button is too small to be easy to operate, so a larger button is needed.Today, I will introduce to you the largest metal button of our company FILN, a big push button switch with a 40 mm mounting aperture.
The installation aperture of the 40mm big push button switch is 40mm, the diameter of the head is 45mm, and the diameter of the button section is 33.5mm, so the 40mm big push button switch greatly increases the area of the operating surface and is more convenient to use.
In addition to the 40mm installation aperture, we also produce 12mm, 16mm, 19mm, 22mm, 25mm, 28mm, 30mm.
The sleeve housing material of the 40mm big push button switch is mainly 304 stainless steel. The housing of 304 stainless steel has high corrosion resistance and is suitable for use in harsh environments without rapid rusting. The sleeve material is also nickel-plated brass and black zinc-aluminum alloy, but these two are not commonly used materials for our large-size big push button switch. If customers want these two materials, we need to customize them. Delivery time It will take a little longer. Among them, the brass nickel-plated shell looks a little yellow, and it looks brighter, and the price is relatively high; the black zinc-aluminum alloy looks very beautiful in appearance, suitable for use in electrical appliances that require black buttons.
There are four main types of big push button switch functions, which are 1NO, 2NO, 1NO1NC, and 2NO2NC. The switch functions of the 40mm big push button switch are 1NO1NC and 2NO2NC.
The big push button switch has two functions: self-locking and self-resetting. Self-locking big push button switch refers to pressing the button, the button will not automatically return. You need to press it again to return. The Self-restoring big push button switch means that after pressing the button finger when the hand is released, the button will automatically return.
The big push button switch can be made without light or with light. Among them, the LED light with light has monochromatic colors of red, yellow, blue, green, white, and two-color colors of red, green, red and yellow, etc. There are red, green and blue, red, yellow and blue lights. The two-color and three-color functions are divided into two types: a common cathode and a common anode. Common cathode means that the public lamp pin is connected to the negative pole of the power supply. A common anode means that the public lamp pin is connected to the positive pole of the power supply. You can follow up on your needs. Common Yin or Common Yang. In addition, the big push button switch can also use two or three lamp beads inside the button to form a two-color or three-color effect. In this case, there is no common cathode and common cathode. You can connect it at will light wire.
The waterproof rating of the big push button switch is IP65. In addition, our button series has obtained UL RoHS CE certification.
The following is the working principle of a big push button switch:
The big push button switch is usually used to switch on and off the control circuit. It is a kind of low-voltage electrical appliance that issues instructions in the electric drive. It is a kind of master electrical appliance that is widely used. It is used for manual transmission in electrical automatic control circuits. Control signals to control contactors, relays, electromagnetic starters, etc. 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, only when there is a request, it will switch to the second state (position) under the action of external force. Once the external force is removed, Due to the action of the spring, the switch returns to the initial position.
The big push button switch can complete the basic control of starting and stopping. Usually, each push button switch has two pairs of contacts. Each pair of contacts consists of a normally open contact and a normally closed contact. When the button is pressed, the two pairs of contacts act at the same time, the normally closed contact is disconnected, and the normally open contact is closed.
The colors of the illuminated big push button switch are red, green, yellow, blue, white, etc. To avoid misoperation, the big push button switch lights are usually made into different colors to show the difference. For example, red means stop, green means start, etc. 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.
A big 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.
The opening and closing state of the contacts when the big push button switch is not subjected to external force (i.e. static) is divided into start button (i.e. normally open button), stop button (i.e. normally closed button) and composite button (i.e. normally open and normally closed touch) The head is combined into one button). For the start button, the contact is closed when the button cap is pressed, and the contact is automatically disconnected and reset after being released; the opposite is true for the stop button, the contact is separated when the button cap is pressed, and the contact is automatically closed and reset when the button is released. The composite button is that when the button cap is pressed, the bridge-type moving contact moves downwards so that the normally closed contact is opened first, then the normally open contact is closed; when the button cap is released, the normally open contact is first After breaking and resetting, the normally open contact is closed and reset.
In addition to the pin big push button switch, we also have a button with a wire style. Compared with the pin button, the button with a wire has the higher waterproof performance. From IP65 to IP67, it is suitable for outdoor use. If the environment is more demanding, then you can try our wired buttons.
