Speed Queen side of
limit switch.

These Speed Queen parts are perfect as limit sw itches since they
are normally open, and close when the plu nger has been pushed
in. Each of the axes requi res two switches-one installed at eit her
end of travel. The switch needs to make contact wit h part of the
moving axis before the axis gets jammed up.

X-axis Limits

On the x-axis motor end. two holes are needed to bolt the limit
switch to the top of the motor and bearing mount (see Figure 9.2 9).
