JM Concept electrical components utilize the good conductivity and fluidity of mercury to control the opening and closing of electrical circuits. They consist of a glass tube, mercury, fixed electrodes, lead wires, etc. After evacuating the air from the tube, it is filled with various gases and sealed. They are suitable for environments with dust, oil, water vapor, and corrosive gases, and can also serve as explosion-proof switches in areas with explosive gases. Due to the high surface tension and specific gravity of the mercury inside the tube, as well as its fluidity, the position of the mercury changes immediately when the glass tube is slightly tilted, making surface contact with the electrodes, thus enabling the switching of high AC and DC currents. Additionally, this type of switch features a lifespan of up to several million cycles at rated current, compact size, high sensitivity, no mechanical noise, and low cost, making it widely used as a switch for automatic control.

JM Concept electrical component characteristics

Resolution refers to the ability of a sensor to detect the smallest change in the measured quantity. That is, if the input changes slowly from a non-zero value, the sensor output will not change until the input change exceeds a certain value, meaning the sensor cannot resolve changes in the input below this threshold. Only when the input change exceeds the resolution does the output change. Typically, the resolution varies across the full scale range of the sensor; therefore, the maximum input change within the full scale that causes a step change in the output is commonly used as the indicator for resolution. If this indicator is expressed as a percentage of the full scale, it is termed resolution. Resolution has a negative correlation with sensor stability.

JM Concept electrical component classification

Classification by application: toggle switches, band switches, record/playback switches, power switches, selector switches, limit switches, control switches, changeover switches, isolator switches, travel switches, wall switches, smart fire protection switches, etc. Classification by structure: micro switches, rocker switches, toggle switches, slide switches, push-button switches, key switches, as well as fashionable membrane switches and dot switches. Classification by contact type: switches can be divided into a type contacts, b type contacts, and c type contacts based on their contact types. The contact type refers to the relationship between the operating condition (pressing the switch) and the state of the contacts after operation. It is necessary to choose a switch with an appropriate contact type according to its intended use. Classification by number of switches: single-control switches, dual-control switches, multi-control switches, dimmer switches, speed control switches, splash-proof boxes, doorbell switches, sensor switches, touch switches, remote control switches, smart switches, card-operated power switches, and dedicated bathroom heater switches.

JM Concept electrical component applications

AC asynchronous motors are the most widely used among various electric motors. They are easy to use, reliable, inexpensive, and robust in structure, but have a low power factor and difficult speed regulation. Synchronous motors are commonly used for high-capacity, low-speed prime movers. Synchronous motors not only have a high power factor, but their speed is independent of load size and depends only on the grid frequency, offering stable operation. DC motors are often used in applications requiring wide-range speed regulation. However, they have commutators, complex structures, high costs, and difficult maintenance, making them unsuitable for harsh environments. With the development of power electronics, AC motor speed control technology is maturing, equipment prices are decreasing, and applications are increasing. The maximum output mechanical power a motor can handle under specified duty cycles without overheating is called its rated power; users must adhere to the nameplate specifications. During operation, ensure the load characteristics match the motor characteristics to avoid runaway or stalling. Motors provide a wide power range, from milliwatts to tens of megawatts. Motor use and control are very convenient, featuring capabilities such as self-starting, acceleration, braking, reversal, and holding. Generally, during speed regulation, the output power of a motor varies with speed.
