Solid state electronic switch for motor vehicles
An apparatus is described for selectably energizing a power consuming device with an electrical current signal from an electrical power source in response to a command signal presented. The apparatus consists of: gated switch means, having a first terminal connected to the power source and a second terminal connected to the power consuming device, for conducting the electrical current signal in the presence of a gate signal presented to a gate input and for not conducting the current signal in the absence of the gate signal; reference signal source means for providing, in the presence of the command signal, a time variant signal representative of reference current signal magnitudes for each of succeeding time intervals occurring in the presence of the command signal; and detection means, responsive to the time variant signal and including sensor means for providing sensed signals indicative of the actual magnitude of the electrical current signal, for providing the gate signal to the gate input in each of the time intervals in which the sensed actual current signal magnitude is less than the reference current signal magnitude.
