About our Switches

Here's what the acronyms mean:

SPDT = Single Pole Single Throw
SPDT = Single Pole Double Throw
DPST = Double Pole Single Throw
DPDT= Double Pole Double Throw
Long Tog. = Long Toggle (1-1/2" long. Standard toggle is 11/16" long)
Mom-Off-Mom = Center off, spring loaded to return to center "off" from
          both "on" positions
Lever = lever operated
Keyed = Key Operated
P-Pull = Push Off, Pull On
HLamp = Headlight Switch, designed to control Headlights & Running lights.

Our toggle, rocker, ignition and battery switches are manufactured by either Cole-Hersee, Pollack, or Hella. These manufacturers are OEM suppliers to companies like Caterpillar, Freightliner and other on and off-road heavy equipment manufacturers, and are widely used in applications like NASCAR and Formula 1.

Here's why: these are all are heavy duty switches, and are far more rugged mechanically and electrically than the switches found in your local retail parts store.
That means they won't fail due to vibration or transient overload like the lower cost switches found in retail stores, and are rated 25 to 75 amps @24VDC. The cheaper switches are rated 10 amps or less.

The toggle, rocker and ignition switch terminals are either .250 quick disconnect (push-on) terminals or #6-32 or #8-32 screw.

The Battery Switches are rated from 175 to 300 amps continuous, and 1000 to 3000 amps intermittent.

The Double Pole Battery Switches have an independent set of contacts to cut off the ignition and alternator. (Otherwise, cutting off the battery wouldn't necessarily stop the motor and fuel pump in an emergency situation. And, it's required by many race sanctioning bodies.)

The Battery Switch terminals are #10/32 studs, for the alternator, and 3/8" studs for the battery circuit.
