AH71553569-A Snap Action, Limit Switches Application Field and Working Principle

The AH71553569-A snap action, limit switch is a device used for controlling an electrical circuit. It works on the principle of a snap-action switch, whereby an actuator, when it moves beyond a certain distance, causes the switch mechanism to rapidly move the contact either together (closing the switch) or apart (opening the switch). It is widely used in controlling a range of applications in the automotive, home appliance, HVAC, and electronic industries.

Applications

The AH71553569-A Snap Action, Limit Switch is a versatile device that is widely used in many different applications and sectors. Such applications include:

• Automotive
• Home white goods
• HVAC
• Electronics

In the automotive industry, the switch is used for controlling and regulating components such as fuel pumps, wipers, starters, windows and more. In home white goods, it can be used for controlling power, on/off settings, thermostats and cooking oil settings. In the HVAC sector, the switch is used for controlling fan settings, temperature and humidifiers. In the electronics industry, limit switches are used for controlling motors, solenoids, and other electro-mechanical components.

Working Principle

The AH71553569-A snap action, limit switch operates using a snap-action switch. The switch has two separate contacts and is composed of an actuator. When the actuator is moved beyond a certain distance, it causes the contacts to rapidly move either together (closing the switch) or apart (opening the switch). The switch is triggered by the movement of some kind of plunger actuator, typically mounted on the side of the switch body. When the plunger is depressed, it causes the switch contacts to move together and make contact. When the plunger is released, the springs push the contacts apart and open the switch.

The switch is made from high-quality materials such as stainless steel, plastic, and bronze. It features a built-in overload protection along with short circuit and reverse polarity protection. The switch also features a wide voltage and temperature range, making it suitable for a wide range of applications.

Conclusion

The AH71553569-A snap action, limit switch is a versatile device that is widely used in automotive, home appliance, HVAC, and electronic applications. It works on the principle of a snap-action switch, whereby an actuator, when it moves beyond a certain distance, causes the switch mechanism to rapidly move the contact either together (closing the switch) or apart (opening the switch). It is made from high-quality materials and features a wide voltage and temperature range, making it suitable for a wide range of applications.
