Abstract
The disclosure describes an impact sensor having an electrical switch for actuation when an optical probe to which it is attached comes within a predetermined distance of an obstruction. An impact or contact element connected with the electrical switch sets the predetermined distance to actuate the switch. A resilient connector, such as piano wires, interconnect the contact element with the electrical switch, whereby the electrical switch is maintained in a non-actuation condition until the optical probe comes within the predetermined distance to the obstruction.
