Abstract

In many instances it is desirable to ascertain the exact position of a moving member, for example, the carrier or other moving implement within a printer. In this connection, it is conventional to employ a brush or other small delicate part positioned against a moving conductive encoder or, for example, against a cam having conductive portions thereon so as to complete a circuit indicating the exact position of the encoder or the cam. The technique described below and illustrated in the drawing utilizes three thin stamped metal fingers individually positioned and attached to a housing, the fingers being formed from conductive paths which are pressed against the rotating encoder or cam for accomplishing the intended purpose.
