Accessories
A pneumatic foot switch or an automatic grip controller are optional accessories
for opening and closing the grips.
Foot Switch
The pneumatic foot switch is a switch assembly and three air lines. Figure 1-4
illustrates the foot switch. Two hoses from the air outlet lines, marked upper grip
and lower grip, have quick disconnect fittings that attach to the corresponding
grips. The third air line has a female threaded fitting on both ends which connects
the foot switch and the air supply.
The design of the pneumatic foot switch lets you open and close the grips while
leaving your hands free for installing and aligning the specimen in the grips. You
can operate the pneumatic grips with an in-house air supply or a small self-
contained compressor.
