HORN RELAY SWITCH ON PHANTOM III CHASSIS. The operation of the horn on the Phantom III chassis is accompanied by an objectionable clicking sound which was thought to emanate from the horn button but which we now find to be in a large measure due to the operation of the relay switch mounted on the dash board. We should be glad if consideration could be given to some method of noise insulating this relay switch by either mounting it in some new position isolated from the dash or in some way insulating the relay switch itself by means of a rubber mounting and special cover.
