Product Selection
“PMS” – Pringle Mill
switches are opened or
closed by means of a side
mounted operating handle,
which compresses disc
springs (Eaton Pringle
exclusive) in the drive
mechanism. The mechanism,
in turn, quickly opens or
closes the switch blades at a
speed independent of the
speed of handle movement.
Additionally, the handle can
override the springs for
positive connection with the
switch blades.
PMS design is typically
sold as an enclosed device
