Multi-Purpose Contacts 66360-1

The 66360-1 standard defines the general design, assembly and testing standards for various types of contacts that are used across a wide variety of applications. This includes contacts for electrical, telecommunications, media and data communications, fire protection systems, automotive, railroad and process control applications. This standard is managed by the American National Standards Institute (ANSI).

A contact is defined as a device for completing a circuit by establishing an electrical connection from one point to another. For example, a standard electrical outlet has two contacts which provide the connection between an electrical cord and the power source. Contacts are used in a variety of devices, including circuit breakers and switches, as well as in industrial machinery and other equipment.

The 66360-1 standard requires that all contacts conform to certain design, assembly and testing requirements in order to assure a reliable electrical connection. Design requirements include the contact’s physical structure and materials, contact capability rating, a rating for corrosion resistance, and a range of temperature ratings.

The design of contacts is also important when considering the various working principles they are capable of providing. Standard electrical contacts are usually keyed for proper orientation, allowing for a specific type of contact action. Other contacts may utilize spring action, in which a specific force must be applied to the contact in order to open or close the circuit. Still other contacts are designed for tactile action, meaning that there is a physical feedback when the contact is opened or closed.

In addition to design requirements, the 66360-1 standard also defines assembly and testing requirements. Assembly requirements cover proper assembly of the contact’s constituent parts to ensure proper operation. This includes proper orientation and alignment of the contact’s parts. Testing requirements include tests for operation, contact reliability and compliance with specified environmental requirements. This includes tests for electrical shock, vibration, corrosion resistance and temperature cycles.

The 66360-1 contacts standard is essential to the delivery of reliable electrical connections in a variety of applications. The various design, assembly and testing requirements ensure that contacts used in the modern environment will provide reliable operation and protect against failure.
