ABSTRACT:
Flexible wire loop slip ring brushes for use in miniaturized gyroscopes. A lurality of flexible wire loop brushes hug or embrace opposite peripheral sides of respective slip rings in resilient sliding contact over a substantial arc for establishing a redundancy of "a" spots for assured paths through which electrical current may pass with minimal resistance. The rings and the brushes are gold alloy which in sliding contact provide good electrical conductivity and low noise.
