ABSTRACT:
An improved clearance detecting device for warning the driver of a vehicle of a impending obstruction. In a detecting device consisting of a base, an antenna, spring means connecting the base and antenna, and an electrical circuit with an alarm device and normally open switch means, the improvement consists of switch means comprising a contact surface and an elongate spring with two ends. One end of the spring is attached to the clearance detector device while the other end is responsive when the antenna is deflected to engage the contact surface so that the electrical circuit is closed and the alarm device activated.
