Introduction

Mounting hardware included with the Safety
Sentry Breakaway Switch kit:

Qty Part

1 Chain/lanyard with snap hook
1 2-1/2" Bolt
1 1-5/8" Sleeve
2 Eyebolts
5 Lockwashers

Failure to follow these
instructions may result in product damage,
equipment damage, and fatal injury to
personnel.

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.

Figure 1 - Typical Layout

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.
