FS-6 Press Brake Foot Switch

These foot switches are designed for some critical
applications such press brake machine control.
These foot switches have at least one of the pedals
with 3 positions, with a pressure point, to control dangerous movements.

For press brake control as an example:
press the pedal to lower down a press brake.
It has 4 working contacts ( 2NC+2NO) to drive
the movement and one safety switches
(1 positive opening NC contact + 1NO)
to stop the movement. Pressing the foot pedal,
until the pressure point where resistance is noticeable.
This allows the changeover of the 2 working contacts
and press is moving downward. When press harder beyond
the pressure point, the 2 working contacts return to
their first position and the positive opening safety contact
is activated as redundant safety circuit in order to initiate
mmediately the dangerous movement. A restart of the
machine is only possible after releasing the foot switch.
