    Broadly defined, it COULD be ANY device that operates on DC (direct current) and uses semiconductors. (transistors or other solid state component.)

    ONE such device is a DC to DC SOLID STATE RELAY.

    Have a look at some, here:

    But, your question is so broad, that EVEN a simple TRANSISTOR, or a THYRISTOR, or many OTHER, solid state devices, could be regarded as a DC semiconductor switch, since if it used in a simple DC, on-off application, it would fit that description.

    Does this help ?
