Electrical appliances are electrical tools used to connect and disconnect circuits or to regulate, control and protect circuits and electrical equipment. Complete automatic control systems consisting of control appliances, called relay-contactor control systems, referred to as electrical control systems.
Electrical appliances are widely used, diverse in function, wide in variety and different in structure. Below are several commonly used electrical categories.
1. Classification according to working voltage level (1) High-voltage electrical appliances are used in electrical circuits with AC voltage of 1200V and DC voltage of 1500V and above. For example, high-voltage circuit breakers, high-voltage isolating switches, high-voltage fuses, etc.
(2) Low-voltage electrical appliances are used for AC 50Hz (or 60Hz), rated voltage is less than 1200V; DC rated voltage is 1500V and below, such as contactors, relays, etc.
2. Classified by action principle
1) Manual electrical appliances that operate by hand or rely on mechanical force, such as manual switches, control buttons, travel switches, etc.
2) Automatic appliances that operate automatically by means of electromagnetic force or a change in physical quantity, such as contactors, various types of relays, solenoid valves, etc.
3. Classification by use (1) Control electrical appliances used in various control circuits and control systems, such as contactors, relays, motor starters, etc.
(2) The main electrical appliance is used in the automatic control system to send action instructions, such as buttons, travel switches, universal transfer switches, etc.
(3) Electrical appliances used to protect electrical circuits and electrical equipment, such as fuses, thermal relays, various protective relays, lightning arresters, etc.
(4) Execution electrical appliances refer to electrical appliances used to perform certain actions or transmission functions, such as electromagnets, electromagnetic clutches, etc.
(5) Electrical appliances used for distribution and distribution of electrical energy, such as high-voltage circuit breakers, isolating switches, knife switches, automatic air switches, etc.
4. Classified by working principle
1) Electromagnetic appliances work according to the principle of electromagnetic induction, such as contactors, various types of electromagnetic relays, etc.
2) Non-electrical control appliances that rely on external forces or certain non-electrical physical quantities to change, such as knife switches, travel switches, buttons, speed relays, temperature relays, etc.

Memory For Mini PC And Desktop
Memory for Mini PC
Form Factor and Type: Mini PCs typically use laptop-style memory modules such as SO-DIMM (Small Outline Dual In-line Memory Module). These modules are smaller in size to fit into the compact form factor of mini PCs.
Capacity Options: The memory capacity for mini PCs usually ranges from 4GB to 64GB or even more in some high-end models.
Impact on Performance: Adequate memory in a mini PC is essential for its smooth operation. With sufficient memory, the mini PC can quickly access and process data, resulting in faster application loading times, seamless multitasking, and better overall system responsiveness. On the other hand, if a mini PC has insufficient memory, it may experience slowdowns, frequent swapping of data between the memory and the storage drive (known as thrashing), and longer waiting times for applications to respond.
Memory for Desktop
Desktop computers mainly use DIMM (Dual In-line Memory Module) memory. DIMM modules are larger in size compared to SO-DIMM used in mini PCs. There are different generations of DIMM memory, such as DDR3, DDR4, and the newer DDR5. DDR5 offers higher bandwidth and lower power consumption compared to its predecessors, enabling better performance for demanding applications.
In conclusion, both mini PCs and desktop computers require appropriate memory configurations to deliver optimal performance.
