INC 00302 Electrical Contact Brush
INC 00302 Electrical Contact Brush

An item specifically designed to be used in the transfer of electrical energy to or from another conducting surface. Either the brush or the surface is continually moving during the transfer of energy. The brush is usually composed in part of some form of the element carbon. Includes: (1) a single brush either with or without an attached shunt (flexible wire lead) and/or a helical or flat type pressure spring; (2) a split brush composed of two or more pieces (wafers), which are used in place of one brush usually connected together by individual shunts to a common terminal; (3) paired brushes composed of two identical or non-identical brushes connected together by a common shunt either with or without pressure springs or connected by individual shunts to a common terminal, or with pressure springs and connected to a common bar, bracket or the like either with or without individual shunts; (4) multiple brushes composed of more than two identical or non-identical brushes without pressure springs connected by individual shunts to a common terminal, or with pressure springs and connected to a common bar, bracket or the like by individual shunts. Does not include moving contacts which make and slide past stationary contacts, but are stationary while the circuit is conducting, such as the sliding contacts on a rheostat or the stationary contact on a synchro. Excludes: CONTACT, ELECTRICAL; and CONTACT ASSEMBLY, ELECTRICAL.

Additional Information for Electrical Contact Brush Additional Information for Electrical Contact Brush

Electrical contact brushes are components used in electrical and electronic equipment to establish and maintain electrical contact between two conductive surfaces. They are typically made of conductive materials such as copper, brass, or bronze, and are designed with bristles or filaments that can effectively transfer electrical current.

These brushes are commonly used in various applications, including:

1. Electrical switches: Contact brushes are used in switches to ensure a reliable and consistent electrical connection when the switch is closed.

2. Slip rings: In rotating machinery, such as motors or generators, slip rings are used to transfer electrical signals or power between stationary and rotating parts. Contact brushes are used to maintain continuous contact with the slip rings, allowing for the transfer of electrical current.

3. Carbon brushes: Carbon brushes are a specific type of electrical contact brush that are commonly used in electric motors and generators. They are made of carbon or graphite, which have good electrical conductivity and can withstand high temperatures.

4. Electrical connectors: Contact brushes are also used in electrical connectors to establish a secure and low-resistance connection between two mating connectors.

Overall, electrical contact brushes play a crucial role in ensuring efficient electrical contact and reliable performance in various electrical and electronic equipment.
