Contacts - Multi Purpose: These types of contacts involve multiple applications and working principles, and 66473-3 contacts are no exception. This contact type is designed for use in a wide range of HVAC applications and is also suitable for lighting control and even industrial applications. Its primary purpose is to provide a single contact point for an HVAC system. It has two contact points, one for an electrical contact and one for a mechanical contact.

66473-3 contacts use a unique mechanism to achieve their purpose. The contact point for the electrical contact is usually the larger of the two, and features what is referred to as the “hump.” This hump is essentially a ledge which allows the electrical current to pass from one contact to the other. The mechanical contact is mounted on the same side of the contact as the electrical contact, and when they are both closed, they form a single contact point.

When a current flows from the humps to the mechanical contact, a small electrical circuit is formed. This circuit is used to control the HVAC system. Depending on the current flow, different levels of power may be sent to various parts of the system, controlling the temperature or humidity of the air, the fan speed, and so on. Basically, using this contact, power can be efficiently and accurately distributed throughout the HVAC system, allowing for control of temperature, humidity, and fan speed.

In addition to HVAC applications, 66473-3 contacts can also be used in lighting control and industrial applications. They are typically used to control the lighting in a building, as well as the various phases involved in industrial machinery. They are excellent for providing power to motors and controlling the speed and direction of motors. Most of the time, these contacts are used with a device such as a STAR-Delta or 3-Phase motor to provide proper control of the motor.

The 66473-3 contact is made from a solid metal material, such as steel, and it is designed to withstand the rigors of harsh environments. This makes them ideal for industrial and commercial applications. They are typically found in air conditioning systems, industrial machinery, lighting control, and a variety of other applications where reliability and durability are paramount.

In summary, 66473-3 contacts are an excellent contact type for a variety of applications, ranging from HVAC, to lighting control, to industrial machine control. They are made from a solid metal material and are designed to withstand the rigors of harsh environments. They use a unique mechanism to enable efficient power distribution throughout a HVAC system, and can be used in a wide range of applications in both commercial and industrial settings.
