Snap action limit switches are mechanical components used as sensing and control devices in a broad range of industrial and commercial applications. The ZD20S20A02 is a snap action limit switch that is used for a wide variety of applications in multiple industrial and commercial industries. This article will discuss the application field and working principle of the ZD20S20A02.

The ZD20 S20A02 is typically used in the appliance, automotive, lighting, HVAC, and automated systems industries. It is typically used to detect a change in an object\'s position or to sense physical parameters such as force or speed. It can be used to actuate a relay or a device such as a motor. In addition, the switch is often used to detect an open or closed circuit and to ensure that a given operation continues when a certain condition is met.

The ZD20S20A02 is a normally open momentary contact limit switch. This type of switch is used when constant power is applied to the switch, the contacts remain closed, and when the power is switched off, the contacts make contact. This type of switch is most commonly used for applications that require a single momentary contact closure. The ZD20S20A02 is also available in normally closed configurations, in which the contacts remain closed until the power is switched off.

The working principle of the ZD20S20A02 is relatively simple. A normally open or closed contact is connected to one end of the switch. When power is applied or the object\'s position is changed, the armature moves, and the contact is closed. When the power is switched off or the object\'s position is changed back to its original position, the armature moves back, and the contact is opened again.

The ZD20S20A02 has a maximum operating temperature range of 65 degrees Celsius, and it is capable of operating up to 25A at 125/250V AC. It is available in a variety of forms, which makes it versatile enough to fit most applications. In addition, the switch is very reliable, with an estimated lifetime of 50 million cycles with proper usage and maintenance.

In conclusion, the ZD20S20A02 is a commonly used snap action limit switch for a wide range of industrial and commercial applications. It is a normally open momentary contact limit switch, with a maximum operating temperature range of 65 degrees Celsius, and a maximum current rating of 25A. It is available in a variety of forms and is highly reliable and durable. The working principle of the switch is relatively simple, and it is easy to install and maintain.
