One minute to take you to understand the double action switch
Double action switchIt has the characteristics of two-way operation, there are two operating positions, each position can control the switch state of the device. When the switch is on one side, the current can pass, and when the switch is on the other side, the current is blocked.
For some devices that need to prevent accidental touch, the double action switch is an important choice. Since there are two operating positions, a force is required in a specific position to trigger the switch. Therefore, the chance of false contact is reduced a lot.
In some occasions with high safety requirements, the double action switch also plays an irreplaceable role. For example, some nuclear power plants are equipped with double-action switches on the control panel to ensure the safety of operation.
However, the design of double-action switches is relatively complicated and the cost is high, so it is not common in some low-end devices. In addition, the double action switch also has a short service life, not easy to clean and other shortcomings.
Learning to use the double action switch is very important. Only at the right time, with the correct method and attitude to adjust their position, in order to get better results.
Double-action switch is a kind of switch with high safety, which has greatly improved the safety compared with single-action switch. However, the advantages of double-action switches are not only this. Here we come to the specific analysis of the advantages of double action switch where.
1. Low error rate. In contrast to a single-action switch, a double-action switch requires a two-step operation to turn the circuit on or off. This effectively reduces the possibility of misoperation, so it is widely used in many important occasions.
2. More suitable for high voltage field. In the high voltage field, the single action switch is easy to burn out because of the instantaneous high temperature. The double-action switch can be turned on and off separately, which greatly reduces the chance of circuit overheating.
3. Prevent false triggering. The operation of some switches is relatively sensitive. If you accidentally touch them, it is easy to operate by mistake. The double action switch needs to apply the corresponding force in two directions to really operate the switch. Can effectively avoid the problem of false trigger.
4. Strong resistance to operation. The double-action switch is designed to withstand greater force and impact, so it is widely used in heavy-duty and high-strength places of use.
5. Widely used. Due to the safety and reliability of the double action switch, it is widely used. From household appliances to high-voltage equipment, from ordinary circuits to railway signals, double-action switches play an important role.
