What is the contact resistance of Micro Switch AZ - 7110?

Hey there! As a supplier of the Micro Switch AZ - 7110, I often get asked about the contact resistance of this little but powerful device. So, let's dig into it and find out what makes the contact resistance of the Micro Switch AZ - 7110 tick.

First off, what the heck is contact resistance? Well, in simple terms, it's the resistance that occurs at the point where two electrical contacts meet. When the switch is closed, current has to flow through this contact area. And just like any other conductor, this contact area has some resistance. It might seem like a small thing, but it can have a big impact on how well the switch works.

For the Micro Switch AZ - 7110, the contact resistance is a crucial factor. It affects the overall performance of the switch, including things like the amount of power loss and the accuracy of electrical signals. A high contact resistance can lead to more power being wasted as heat, which isn't good for the switch's lifespan or for the efficiency of the circuit it's in.

The contact resistance of the Micro Switch AZ - 7110 is designed to be as low as possible. This is achieved through a combination of high - quality materials and precise manufacturing processes. The contacts in this switch are made from materials that have good electrical conductivity, like certain alloys. These materials are carefully selected to ensure that they can handle the electrical current without causing too much resistance.

Another important aspect is the surface finish of the contacts. A smooth and clean contact surface helps to reduce the contact resistance. During the manufacturing of the Micro Switch AZ - 7110, special attention is paid to the surface treatment of the contacts. This includes processes like plating to create a uniform and conductive surface.

Now, let's talk about how the contact resistance can change over time. One of the main factors that can affect it is wear and tear. Every time the switch is opened and closed, there's a small amount of mechanical stress on the contacts. This can cause the surface of the contacts to become rough or develop small pits, which in turn increases the contact resistance.

Environmental factors also play a role. For example, if the switch is used in a dusty or humid environment, dirt and moisture can build up on the contacts. This can create an insulating layer, increasing the resistance. That's why the Micro Switch AZ - 7110 is designed to be durable and resistant to environmental factors. It has a protective housing that helps to keep out dust and moisture, reducing the risk of an increase in contact resistance.

To measure the contact resistance of the Micro Switch AZ - 7110, special testing equipment is used. This equipment can accurately measure the resistance at the contacts when the switch is closed. During the production process, each switch is tested to ensure that its contact resistance meets the specified standards.

If you're in the market for a reliable micro - switch, the Micro Switch AZ - 7110 is a great choice. Its low contact resistance means better performance and efficiency for your electrical circuits.
