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. Suitable 4-wire plug leads are

available.

Ratings:

250VAC/300VDC

3A

IP67

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:

Note: There is space under the terminal cover to allow the fitting of a small amount of

control components, e.g. relays, terminal blocks etc., which should be secured to

prevent interference with the footswitch mechanism.

Terminal screws: M3.5

with rising cable clamps.

Maximum screw

tightening torque:

0.8Nm (8kg cm).
