Introduction

A 66428-4 contact is a multi purpose contact that is used in a variety of applications. It is designed to be used in any type of relatively low power, high current switch with a low level of contact resistance. This type of contact consists of two parts: the contact and the base. The base is made of either nickel or brass and the contact is composed of a variety of metals, including stainless steel, silver plated brass, and copper.

Applications

The 66428-4 contact is used in a number of different applications. It is found in automotive ignition systems, security systems, elevators, industrial control systems, and pump systems. It is used in applications with low power/high current switching, low voltage/high current switching, and eliminating arcing of an electrical contact.

Working Principle

The 66428-4 contact works on the principle of contact resistance. When the two parts, the contact and the base, are brought together, the contact creates a continuous electrical path, allowing the current to flow. The contact resistance of the contact is what is responsible for low power and high current switching. As the contact gets worn down, the resistance increases, causing the current to be reduced, thereby creating a low voltage/high current switching effect.

Why Use the 66428-4 Contact?

The 66428-4 contact is designed to provide a reliable and durable contact for a variety of applications. It is designed to reduce arcing of an electrical contact, making it safer for use in any application where contact resistance could potentially become an issue. Furthermore, the contact is corrosion-resistant, making it ideal for use in harsh environments or with corrosive materials.

Conclusion

The 66428-4 contact is a multi purpose contact designed for use in low power/high current switch applications with a low level of contact resistance. It is corrosion-resistant, eliminating arcing of an electrical contact, and provides a reliable and durable contact for a variety of applications. For these reasons, it is an ideal choice for anyone looking for an all-purpose switch contact.
