SOLIGHT electrical components are a commonly used low-current master control device. They utilize the collision of moving parts of production machinery to actuate their contacts, thereby making or breaking control circuits to achieve specific control objectives. Typically, such switches are used to limit the position or travel of mechanical motion, enabling moving machinery to automatically stop, reverse, change speed, or perform automatic reciprocating motion at predetermined positions or travel limits. In electrical control systems, the role of position switches is to implement sequence control, positioning control, and detection of position status. They are used to control the travel of mechanical equipment and provide limit protection. Construction: Composed of an operating head, contact system, and housing. In actual production, limit switches are installed at pre-arranged positions. When a module mounted on the moving part of the production machinery strikes the limit switch, the contacts of the limit switch actuate, achieving circuit switching. Therefore, a limit switch is an electrical device that switches circuits based on the travel position of moving parts; its operating principle is similar to that of a pushbutton. Limit switches are widely used in various machine tools and lifting machinery to control their travel and provide terminal limit protection. In elevator control circuits, limit switches are also used to control the speed of opening and closing car doors, provide automatic door open/close limit protection, and provide upper and lower limit protection for the car.

SOLIGHT electrical components composition

A sensor generally consists of four parts: a sensing element, a conversion element, a signal conditioning circuit, and an auxiliary power supply. The sensing element directly senses the measured quantity and outputs a physical quantity signal that has a definite relationship with the measured quantity. The conversion element converts the physical quantity signal output by the sensing element into an electrical signal. The signal conditioning circuit is responsible for amplifying and modulating the electrical signal output by the conversion element. The conversion element and the signal conditioning circuit generally require power from the auxiliary power supply.

SOLIGHT electrical components function

The starter solenoid switch is a key component of the starter motor, and the design quality of the solenoid switch directly affects the reliability of the starter. The starter solenoid switch has two functions: first, it connects the main circuit to rotate the starter motor; second, it pushes the drive gear out via a shift fork to engage with the engine flywheel ring gear. Therefore, the solenoid switch is required to have corresponding attraction force, corresponding travel, and contacts capable of reliably making and breaking high currents. Additionally, it is required to minimize volume and weight as much as possible. Based on these characteristics, the contact structure of solenoid switches generally adopts a contact form, i.e., the moving contacts are made in bridge or disc shapes to provide a larger heat dissipation surface and thermal capacity. The magnetic system mostly adopts a solenoid electromagnet structure to meet the requirements for corresponding travel, corresponding attraction force, small volume, and light weight. The moving iron core of the solenoid switch can move smoothly within a brass bushing equipped with a solenoid coil. The pull rod of the moving iron core is connected to the one-way clutch via a shift fork. Under the action of the return spring, the moving iron core remains in the non-operating initial position under normal conditions. During starting, the starter drive gear needs to move forward by approximately 12-26mm. Therefore, when the solenoid switch begins to close, a large magnetomotive force is required to generate the necessary initial attraction force. After actuation, the air gap decreases, and the electromagnetic attraction force increases sharply, far exceeding the force required to maintain the closed state. For this reason, the solenoid switch employs two coils (an attraction coil and a holding coil). Initially, both the attraction coil and the holding coil jointly generate electromagnetic attraction. After the switch contacts close, the attraction coil automatically disengages from the operating state, and only the holding coil maintains the switch in the closed state. The current in the holding coil is relatively small, allowing it to be wound with thinner wire. This reduces the volume of the solenoid switch while achieving reasonable attraction force matching. To ensure the reliability of the starter motor, particular attention must be paid to the design quality of the solenoid switch.

SOLIGHT electrical components types

For different application scenarios, the purpose of using varistors varies, and the voltage/current applied to the varistor differs accordingly. Thus, the requirements for varistors also differ. Distinguishing these differences is crucial for correct usage. Depending on the purpose of use, varistors can be divided into two categories: (1) protection varistors and (2) circuit function varistors. Protection varistors: 1 Distinguish between varistors for power supply protection and varistors for signal line or data line protection, as they must meet different technical standard requirements. 2 Depending on the continuous operating voltage applied to the varistor, varistors across power lines can be classified into AC type or DC type. Varistors exhibit different aging characteristics under these two voltage stress conditions. 3 Depending on the abnormal overvoltage characteristics withstand by the varistor, varistors can be classified into three types: surge suppression type, high-power type, and high-energy type. 1 Surge suppression varistors refer to varistors used to suppress transient overvoltages such as lightning overvoltages and switching overvoltages. The occurrence of such transient overvoltages is random and non-periodic, and the peak current and voltage values can be very high. The vast majority of varistors belong to this category. 2 High-power varistors refer to varistors used to absorb continuous pulse groups that occur periodically, such as varistors connected in parallel to switching power supply converters. Here, impact voltages occur periodically with a known period, and the energy value can generally be calculated. Although the peak voltage is not very high, the average power is considerable due to the high frequency of occurrence. 12 High-energy varistors refer to varistors used to absorb magnetic energy in large inductive coils such as generator excitation coils and lifting electromagnet coils. For such applications, the main technical indicator is energy absorption capability. The protective function of varistors can be repeated multiple times in most application scenarios, but sometimes they are designed as "one-time" protective devices similar to current fuses. For example, varistors with short-circuit contacts connected in parallel to the loads of certain current transformers.
