Introduction
The main purpose of any trailer breakaway switch is to automatically engage the electric trailer brakes should the trailer become detached from the towing vehicle. In addition to this basic function, your Safety Sentry Breakaway Switch will:
1.Test the battery under load for approximately 10 volts minimum.
2.Illuminate its green light to indicate that the trailer battery and breakaway switch are
operating properly.

Mounting
Note the general layout in Figure 1 as you proceed through the mounting instructions. Refer to the parts list, page 2.
1.Drill a 9/32-inch hole for an eyebolt in a convenient structural member on your towing vehicle chassis near the hitch (not on the hitch assembly).
Mount the eyebolt, with the eyebolt pointing toward the breakaway switch, using two 1/4-inch nuts with lockwashers. Tighten securely. See Figure 2.

2.Position the breakaway switch on a horizontal or vertical surface of the trailer tongue or A- frame. The pin in the switch must point towards the towing vehicle.
The switch must be positioned far enough forward so the lanyard will reach the towing vehicle.
It must also be set back far enough to allow an eyebolt to be mounted to the tongue in front of the switch.
3.Drill a 9/32-inch hole through the tongue for mounting the switch.
Insert the furnished metal sleeve into the mounting hole in the switch. The sleeve allows the switch to pivot so the lanyard stays aligned with the towing vehicle.
Bolt the switch to the tongue using the bolt, nut, and lockwasher provided.
