Terminology - Forces - Positions - Travel
The reference point for the figures given for travel and forces is a point F situated on the button in the case of a plain microswitch, or, generally, 3 mm in from the end of a plain actuator.
The reference point for the positions is one of the fixing holes, unless otherwise indicated.

RP Rest position
Position of the operating device
when no external mechanical force is
applied. Also described as "height at
rest".

RP
OF Operating Force
Maximum force which must be applied to
the operating device to displace the rest
position RP to the tripping point TP.
TP Tripping point
Position of the operating device relative
to the fixing point (hole, face) at the
moment when the microswitch trips.
PT Pre-travel
Distance between the rest position RP
and the tripping point TP.

force
OL Overtravel limit
Position of the operating device when an
extreme force has moved it to the
effective end of the available travel.
TTF Total travel force
Force required to displace the operating
device from its rest position RP to its
overtravel limit position. (We only specify
this value if it is higher than the operating
force. When not quoted, it is equal to or
less than the operating force).
MOF Maximum overtravel force
The maximum force which can be
applied to the operating device, without
damaging it, in the end of travel position
where it is in abutment internally or
against the face of the case.
OT Overtravel
Distance between the tripping point TP
and the overtravel limit OL.

RLP Release position
Position of the operating device at the
moment when the snap-action mechanism
trips on its return to its original position.
RF Release force
Force to which the operating force must
be reduced to allow the snap-action
mechanism to return to its release
position RLP.
DT Differential travel
Distance between the tripping point TP
and the release position RLP.
