Miniature bellows contact springs insure electrical connections

Miniature, flexible, gold-plated bellows contact springs like this insure reliable electrical continuity.

They are for electrical connection applications where tolerance buildup, vibration, and thermal expansion become a problem with lifetime spring and force repeatability. Spring flexibility allows them to minimize shock and vibration in dynamic applications.

Because of very low spring-rates, force requirements of 0.04-oz per 0.001 in. of travel are available. This allows designs to be made where contact with a delicate component or material is required. The springs come in diameters from 0.02-in. / 0.5-mm to 0.245 in. / 6.2 mm from electrodeposited nickel alloy and gold-plated to ASTM B 488-01 for enhance conductivity.
