I believe that everyone is familiar with the switch, and every household cannot do without it. A switch is an electronic component that can energize a circuit, terminate current, or pass current to other circuits. The electrical switch is an electrical accessory that connects and cuts off the current; the socket switch is responsible for the connection between the electrical plug and the power supply. Switches bring safety and convenience to our daily electricity use. The closure of the switch represents the path to the electronic node, allowing current to flow. The disconnection of the switch means that the electronic contacts are non-conductive, no current is allowed to pass through, and the load device cannot work to form a disconnection.
There are various types of switches, mainly in the following categories:
1.Classified by use:
fluctuation switch, power switch, preselection switch, limit switch, control switch, transfer switch, travel switch, etc.
2.According to the structure classification:
micro switch, rocker switch, toggle switch, button switch, key switch, membrane switch, point switch, rotary switch.
3.Classification according to contact type:
switches can be divided into three types: a-type contact, b-type contact and c-type contact according to the contact type. The contact type refers to the relationship between the operating condition and the contact state, “after the switch is operated (pressed), the contact is closed”. It is necessary to select a switch with an appropriate contact type according to the application.
4.Classified according to the number of switches:
single-control switch, double-control switch, multi-control switch, dimmer switch, speed control switch, doorbell switch, inductionswitch, touch switch, remote control switch, smart switch.
So do you know where button switches are used?
Give a few examples of important pushbutton switches
1.LA38 push button switch(Similar types of Xb2 buttons are also called lay5 buttons, y090 buttons, high current buttons)
The la38 series is a 10a high current button, which is usually used to start and stop the equipment in large start control equipment.Usually used in some industrial CNC machines, machine tool equipment, children’s rocking chairs, relay control boxes, power engines, new energy machines, electromagnetic starters, etc.
2.Metal shell push button switch(AGQ series,GQ series)
The metal buttons are all made of metal materials.It is mainly punched out with a mold, and can also be made with a laser. which are waterproof and dustproof. It has high strength and anti-destructive performance, not only beautiful and elegant, but also has the advantages of complete varieties, complete specifications and wide range.
Metal push buttons are not only practical but also have a variety of styles. Push-type metal buttons are usually used in Charging piles, medical equipment, coffee machines, yachts, pump control panels, doorbells, horns, computers, motorcycles, automobiles, tractors, audio, industrial machines, machine tool equipment, purifiers, ice cream machines, model control panels and other equipment.
3. Emergency stop switch(Plastic arrow emergency stop,Metal zinc aluminum alloy button)
The emergency stop button is also the emergency start and stop button. When an emergency occurs, people can quickly press this button to achieve protection. Eye-catching red buttons can be seen on some large-scale machinery and equipment or on electrical appliances. The method of using the button can quickly stop the entire equipment immediately by pressing down. If you need to reset the equipment, just rotate the button clockwise. Release the head after about 45°, and the head will automatically spring back.
In industrial safety, it is required that any machine whose transmission parts will directly or indirectly cause harm to the human body in the event of abnormal conditions must take protective measures, and the emergency stop button is one of them. Therefore, an emergency stop button switch must be added when designing some machines with transmission parts. It can be seen that the emergency stop button plays a very important role in the industry.
