Whether in the electrical industry or the home appliance industry, switches are a key component that interrupts the power supply of equipment. The main function is to cut off and open the current in the equipment, so that your equipment can keep running or stopped. With the development of technology, switches have become inseparable from our daily work and life. In this article, we introduce several commonly used electrical switches.
Push button switch
As the name suggests, the push button switch is to realize the function of connecting and disconnecting the current in the equipment by pressing the button up and down. Usually, the installation form and button of the push button switch are round, because there is no direction distinction when the switch realizes the function, and the main thing to realize is the concave and convex form. The spring and hook inside the button keep the normally open or normally closed state. Similarly, the buttons of the push button switch have many different shapes and colors. They represent the unique functions and effects of their own industry, and can more intuitively let users clearly know the specific purpose and usage habits of the switch.
Micro switch
Micro switch is also called micro travel switch. The switch has different operating forces, but the switch triggering stroke is usually very small, and the relative reaction speed is very fast. The life of the electrical switch is also quite long, with a service life of hundreds of thousands, millions, or even tens of millions of times (internationally outstanding micro switches include brands such as Omron and Honeywell)
The micro switch also has an additional accessory, which is its drive. It is usually made of stainless steel pressure rods, or pressure rods with rollers, which can better drive the switch to connect and interrupt the power supply of the device. As early as the last century, due to technical problems, most micro switches were small currents and signal currents, but with the development of technology, new silver contact materials have been upgraded, and micro switches can also pass large currents to 20A or 30A. WEUP specializes in the research and development of switches and has solved the problem of using large currents for major brands around the world.
Electromagnetic switch
Electromagnetic switch is also called magnetic switch. It can automatically absorb and drive the circuit to connect through the coil. Similarly, the electromagnetic coil is connected to the contact piece of the switch body, so that the switch can keep the power on. If you want to cut off the power, just cut off the power supply of the coil to make the electromagnetic lose its magnetism and the electromagnetic switch can achieve the power-off function. So what special functions does the electromagnetic have? Here we need to introduce the most powerful function of the electromagnetic switch in detail. That is, when the electromagnetic switch is powered off, the electromagnetic coil will automatically disengage when there is no current in the electromagnetic coil. This is especially for areas with frequent power outages. This can ensure the personal safety of the operator and the equipment will not continue to work when the power is repeatedly called.
Another very important function of the electromagnetic switch is that when the voltage is unstable, the electromagnetic coil cannot maintain the driver of the switch due to the strength of the magnetic force, so the power supply of the switch is cut off. Similarly, after the switch is cut off, the switch needs to be manually started to make the equipment operate normally. If the voltage used by your equipment is unstable, the electromagnetic switch is your best choice.
Boat switch
Boat switch is also called rocker switch. Its appearance is square, round or oval. The main feature is that its actuator button is like a boat or a rocker. Just push the button a little harder and one side of the button can start the switch. It is usually indicated by “O” or “I”. O usually indicates the disconnected state, and I indicates the connected state. This allows users to know the working state of the switch more intuitively. Most of the rocker switches can be upgraded to have a light function. In a dark or low-light place, the position and function of the switch can be better operated at a glance.
A rocker switch has a single button, a double button, and three buttons. This can better implement the unique functions of the device. So the rocker switch is the most common switch here. If your device has any unique design, please contact us. We will design a switch that best suits your application to replace your original switch and make your device more perfect.
Toggle switch
The toggle switch is driven mainly by the metal lever on the switch. The important functions of the toggle switch are similar to those of the rocker switch. The main difference is the driver and installation. Usually the toggle switch is installed in a round hole. Similarly, the toggle switch is stronger than the rocker switch. Most of the wave switches are made of metal and bakelite lamp materials.
The toggle switch has a unique function. The toggle switch is installed on a switch panel. This panel has a very safe function, that is, it will not cause the equipment to be misoperated due to careless touch, causing danger. It is usually used in airplanes or racing cars.
Tactile switch
Tactile switch is also a kind of button switch, but its operating force is very small, so everyone calls it a touch switch. Tactile switches are self-locking and non-self-locking. Usually, the current of the touch switch is relatively small. They are all used in integrated circuits on PCB circuit boards, especially on button-intensive operation panels, typically on the operation panels of CNC equipment.
The above are relatively common switches, but there are more switches in the industrial industry. This article will not introduce them one by one. If you need any switches, please contact us directly.
