Pushbutton Switches

The ALD31120DNUW is a type of pushbutton switch, specifically a momentary action spring return switch. Pushbutton switches are electro-mechanical components against which a user can push, triggering an operating sequence and then releasing it at the end.

The ALD31120DNUW pushbutton switch is most often used in control systems and industrial automation as part of a network of devices that communicates with each other. It is important to note that this switch is only momentary action, meaning that power is applied to the switch only while it is being pushed. The switch will not stay in the "on" position after being released. This is a versatile switch which can be used in many applications ranging from HVAC systems to medical monitoring systems.

Application Field

The ALD31120DNUW pushbutton switch is a versatile and reliable switch with a wide range of applications. As an example, one can use the switch for HVAC and air conditioning systems, allowing users to quickly switch on or off the machines. Additionally, the pushbutton switch can be used for signalling and alarm systems. It could be used to detect a threshold level and then trigger an alarm or other signals. This can be especially useful in medical monitoring or industrial settings.

The ALD31120DNUW also has many applications in control systems, such as motor control, switching on/off lighting, switching between operational modes and many others. The versatility of this switch makes it a popular choice for many industries, including healthcare and defence.

Working Principle

The ALD31120DNUW works using two main principles: two-position switching and momentary action. Firstly, the two-position switching principle is used to switch between two different states, either on or off. Secondly, the momentary action means that the contact is only made when the switch is activated by a user pushing it, and the contact is lost when the user has finished pushing it. This ensures that the switch will not stay in the "on" position after being released, thus ensuring a dependable operation.

The most common form of contact mechanism used in the ALD31120DNUW is the snap action switch. This type of switch consists of a frame fitted with two internal contact blocks. When pushed, the contacts are brought together and a connection is made; when the switch is released, the contacts are separated again. The snap action makes this type of switch very reliable and popular among industrialists and DIYers alike.

In addition to the contacts, the ALD31120DNUW also uses a coil to create a magnetic field which keeps the contacts in place. The coil is used in conjunction with an N/O (normal open) contact, allowing for a positive locking of the switch in the “on” position.

Conclusion

The ALD31120DNUW is a versatile and reliable pushbutton switch. It is momentary action, meaning that power is applied to the switch only while it is being pushed and the contact is made when the switch is opened. The switch is suitable for a wide range of applications, including HVAC and medical monitoring systems. It uses two main principles: two-position switching and snap action to ensure dependable operation. This makes the ALD31120DNUW a popular choice for many industries, including healthcare and defence.
