Abstract

A manually operated control mechanism for permitting a high frequency detection signal to be selectively produced is provided. A selection circuit is coupled to a divider circuit for receiving therefrom a low frequency timekeeping signal and a higher frequency detection signal. The selection circuit is normally disposed in a first mode and transmits the low frequency timekeeping signal applied thereto and is adapted to be disposed into a second mode to thereby transmit the higher frequency detection signal applied thereto. A manually operative member is adapted to be coordinately displaced between a first non-engaging position and a second position wherein the manually operative member engages said selection circuit to thereby dispose same in a second mode in order to effect the transmission thereby of the higher frequency detection signal.
