Golf club angular orientation indicating device
摘要:
A golf club angular orientation indicating device includes an indicator housing, a switch plate and a shaft clamp. The shaft clamp is slidably received by the indicator housing. An orientation bore is formed in the indicator housing to receive the switch plate. The switch plate is retained on one end by the indicator housing and on the other end by a power plate. The switch plate includes at least two tilt switches mounted on at least two spring loaded pivot plates. A hold down bolt is used to adjust the angular orientation of the at least two tilt switches. Power is preferably supplied to the at least two tilt switches through at least one battery and an on-off switch. Closing the circuit of the at least two tilt switches will supply power to a light emitting device and/or a sound emitting device.
