Applications
Foot switch operated machines such as: shearing machines, spinning machines, spinning lathers, machine tools, wrapping machines, riveting presses, etc.
Foot switches come in five operation formats:
• Free movement: contact position follows pedal movement: actuated when the pedal is pushed down, released when pedal is in state of rest.
• Foot switch locked in neutral position: same operation as above, after unlocking the pedal with the end of the foot.
• Foot switch latched in low position: same operation as free movement, excepted that a state of rest is obtained only after having unlatched the pedal with
the end of the foot.
• Free movement with two-stage actuating force: two different contact blocks are actuated with a different force on the lever.
• Foot switch locked in neutral position with two-stage actuating force: same operation as above, after unlocking the pedal with the end of the foot

Foot Switches PS... / PD...
Double insulation - Plastic Casing IP65 - Description
Devices
1: Free movement of the lever
The lever can be actuated without any particular
device.
2: Movement of the lever dependent of the safety device notch
The pedal can be actuated only by lowering the safety lever fully inserting the foot, thus preventing any accidental actuation.
4: Free movement with two-stage actuating force
5: With safety device notch and two-stage actuating force
Same as above but the pedal can be actuated only by completely inserting the foot in the device.
By applying a light pressure F1 on the lever, the
first contact block will be actuated while the sec-
ond keeps in state.
An higher pressure F2 on the lever will switch also
the second contact block.
3: Device to maintain the lever in lowered position
By pushing the lever the contact switches and the lever remains locked in lowered position.
Push the locking device in order to unlock the
pedal actuator.
Once you release the lever the contacts return to
their initial position.
