<p>PURPOSE:To preclude a contact accident beforehand by using a pressure-sensitive conductive rubber sheet for a switch part and fitting the switch to the bumper of an automobile. CONSTITUTION:An electric conductor 5 is connected to electrode substrates 1 and 2 and the pressure-sensitive, conductive rubber sheet 3 is sandwiched between the substrates 1 and 2. the whole body is covered with an insulating protection material 4. The pressure-sensitive switch is put in a pedestal 6 and covered with a sensing cover 7 to form the contact accident preventive sensor. The contact accident preventive sensor is fitted to the bumper of the automobile. Consequently, the switch of the sensor is turned on at the time of contacting and a buzzer sounds to preclude a contact accident before it happens.</p> |
