Review on Kleinn Air Horns 318 Detonator with Red Activator Button by Joe Garczynski

Tough little horn. The threads on the barrel, bezel nut, and support nut are very thin and not as deep as others have noted. Hope they last many years. The rear contacts are brass with fine thread screws to either attach the crimp terminals or alternatively place the bare stranded wire into the brass blocks (see product image) and tighten the terminal screws. The screws on the switch we received were properly cut/threaded. The momentary switch works as follows: When the button is pressed, the phenolic separator separating the internal copper contacts has a rivet contact at (middle point) which (when the button is pressed) can touch the copper contacts and the buzzer (or other connected Device). When the horn button is returned to the depressed position, the copper contacts are again separated by a phenolic separator.
