1. A multi-position electrical connector, comprising:
- a first connector member having only one conductor, said conductor having only three electrical contacts, said contacts being symmetrically arranged with respect to each other; and
a second connector member comprising a set of three symmetrically arranged lead terminals;
said first and second connector members being arranged to be engageable with each other in three different relative positions such that said conductor selectively provides three direct paths of electrical continuity between;
(a) all three said lead terminals;
(b) a first set of only two said lead terminals; and
(c) a second set of only two said lead terminals;
wherein said second connector member comprises four engagement locations for selectively engaging said three electrical contacts, and said three direct paths of electrical continuity are attainable by selectively engaging said three contacts with said second connector member at said four engagement locations.

Abstract
A plug and socket form a simple and compact electrical connector for selectively distributing an electrical signal along different paths. The plug and socket are symmetrically arranged so that they are engageable with each other in different positions to achieve different electrical connections. The electrical connector saves printed circuit board space, minimizes parts, and improves switching flexibility in an RF signal amplification device for amplifying an RF (e.g., CATV) signal transmitted along an RF cable, and in a power coupler for coupling an AC power signal into an RF cable.
