Abstract:
A temperature-protected electrical switch component, comprising:a switch component conducting a load current;a first temperature sensor disposed at a first location, said first temperature sensor effecting an oscillation of the load current by causing said switch component to switch the load current off when a temperature detected by said first temperature sensor exceeds a first threshold value and to switch the load current on when the temperature detected by said first temperature sensor falls below a second threshold value, the second threshold value lying below the first threshold value;a second temperature sensor disposed at a second location spaced apart from said first location, said second location assuming a lower temperature than said first location during an operation of said switch component, said second temperature sensor having a third threshold value below the second threshold value and a fourth threshold value below the third threshold value, said second temperature sensor causing said switch component to switch off the oscillation of the load current when the temperature detected by said second temperature sensor exceeds the third threshold value and to switch the oscillation back on when the temperature detected by said second temperature sensor falls below the fourth threshold value.
