Footswitches
PX/ PA
Heavy duty footswitches with shrouded pedal to prevent
accidental operation
■
Large shroud to allow operators to wear industrial protective
footwear
■
Pedal interlock lever to prevent operation unless the
operator’s foot is fully inside the pedal shroud
10A 500VAC/ 600VDC rated
Bifurcated contacts for low resistance and high reliability –
suitable for switching low-level electronic currents
Positive break of NC contacts for safety circuits in
conformity with BS60947-5-1, VDE 0660 part 206 and IEC
337-1
A second contact block can be fitted giving a total of four
contacts in various combinations of NO and NC
Unshrouded models (stop type) with red terminal cover
Impact-resistant glass-reinforced thermoplastic housing
Non-skid rubber feet plus floor-fixing holes if required

Cable glands
Contact blocks
Cable glands are available to enable standard multi-core cables to be connected
without the use of conduit. Two sizes are possible:
The contact blocks can also be purchased
separately without the footswitches and be
used as stand-alone limit switches.
The contacts are electrically separated so it is
possible to connect different voltages to NO and
NC circuits i.e. Zb contacts. The NC contacts also
have positive break, i.e. suitable for safety circuits.
Contact arrangements:

All PX series footswitches can be converted to a plug-in style by the addition of
an adaptor. See previous page for diagram.
The adaptor is screwed into the footswitch and the four flying leads connected to
the four terminals of the contact block.

Note: There is space under the ter minal cover to allow the fitting of a small amount of
control components, e.g. relays, ter minal blocks etc., which should be secured to
prevent inter ference with the footswitch mechanism.
