Working breakaway switches are essential equipment on all travel trailers. A breakaway switch automatically sets the trailer brakes in case of accidental trailer breakaway.
Breakaway switch manufacturers recommend that the units be replaced every 3 to 5 years.
Most breakaway switches available today have plastic housings. This all metal breakaway switch is the same style used for decades. The pull pin is brass and contact points are silver so they remain corrosion-free for positive contact.
