We offer three different
push button switches to operate your start gate equipment. The push buttons
may be used to trigger your gate directly, or if you are using our light
tree, they may be used to initiate the light tree count down.
The switches are often
purchased as a backup method of operating the start gates in the event that
there are problems with the computer, or light tree.
Switches are supplied
with an 8 foot cable because they are most often used at a computer postion
located at the starting line. Other cable lengths available on special order.
All switches look identical
from the outside. The difference is what is inside. Here are the three models
with the cover removed for clarity.
Model PB1 $19
Use the PB1 on Latching
Start Gates, Model GLB, GLM, or GLW which require only the closure of a
circuit to operate.
The PB2 contains a Lithium
battery and will operate Latching Start Gates Model GLB, GLM, or GLW. They
can also be used to start the count down of our Light Trees. The
PB2 can activate the Full Motion gates directly, but is not recommended.
See the Model PB3 below.
The PB3 contains a Lithium
battery and a pulse stretching circuit. This is the recommended model to
be used to operate Full Motion Start Gates. The pulse stretcher gives a
2.5 second pulse even if you just momentarily touch the button. The idea
is to insure the cars are safely past the pegs so that they will not be
thrown off the track if the pegs return too early.
