Looks like it would have to be a grounding switch with only two terminals. Juat make sure you get a good ground between the switch and where you mount it.

Run another wire from the ground terminal of the horn to the switch. I would put an inline fuse in the hot wire. Evidently the switch grounds the circuit.
