A golf swing training device configured to be removably attached to the handle of a standard golf club. The training device includes a light source that generates a parallel light beam, such as a laser beam, which enables a golfer using this device to visually monitor the position of the club with accuracy throughout the golf swing. The light source is enclosed within a pair of housings that are threadably coupled, such that the light source is activated by rotating one of the housings relative to the other. The method of activation employs an elasteromic member that permits current flow from a battery to the light source upon the elastomeric member being sufficiently compressed in order to achieve electrical contact between one of the battery's contacts and the housing in which the elastomeric member is contained. |
