Contacts - Multi Purpose categorizes the 66582-4 application field and working principle as being especially suited for applications in which the contacts are required to switch multiple functions. These functions can be typically seen in applications such as airplane engines, off-shore platforms, military electronics and other high-performance applications, where contacts are typically used to control multiple sensors, or manipulate other components. In these cases, the contacts must be able to switch between multiple functions without creating a risk of mis-operation.

The 66582-4 contacts are uniquely designed with an innovative combination of bi-metal contact technology and micro-contacts to provide reliable switching performance even when exposed to extreme environments. The contact construction includes a dedicated "side switch" which brings two additional contact surfaces into action when an activated contact is moved to one side. This unique feature enables the contacts to switch multiple functions with minimal power consumption and reduced electromagnetic interference.

The working principle of the 66582-4 contacts is based on the use of an electrically balanced bi-metal contact to activate an internal mechanical latch. This latch is set to either the open or closed position, depending on the status of the inputs. When the contact input is in the open position, a spring-loaded coil on the bimetal disc will push the disc until it flips over and creates a separate contact pair. When the contact input is in the closed position, the spring-loaded coil will push down the bi-metal disc forcing the two contact surfaces to align. The 66582-4 is designed so that when a circuit is closed, the electrical current is conducted through the two contact surfaces, thus enabling switching between multiple functions.

The 66582-4 contacts offer several advantages in comparison to conventional contacts. The high temperature operation range of the 66582-4 contacts is unmatched, and allows for superior performance in extreme temperature environments. This feature makes them ideal for aerospace and off-shore applications. The contacts also offer superior protection against contact mis-operation, and can provide reliable switching performance even in high vibration environments. Finally, the contacts are designed to perform extremely well in applications requiring rapid switching performance.

In conclusion, the 66582-4 contacts are excellent choices in applications which require multiple functions to be switched with minimal power consumption and reduced electromagnetic interference. These contacts offer superior temperature operation range and protection against contact mis-operation, making them ideal for aerospace, off-shore and military applications. Additionally, the contacts offer rapid switching performance, which suits them for applications which require fast and reliable switching. The 66582-4 contacts remain a leading choice for multiple-function switching solutions.
