Abstract
The hybrid relay may include a plurality of input and output terminals, and a voltage supply terminal. The hybrid relay may also include an electromagnetic coil connected to the input terminals and a latching mechanism that may include first and second contacts movable between open and closed latched positions based upon the electromagnetic coil. The first contact may be connected to the voltage supply terminal so that the second contact provides a switched voltage supply. The hybrid relay may also include an output transistor having a control terminal and having conduction terminals connected to the output terminals of the hybrid relay. A transistor driver may be connected between the switched voltage supply and the control terminal of the output transistor.
