How to read and understand the bar chart information
The following example relates to a unit which has a snap action basic and which has a roller
pin plunger actuator. Follow the black arrows and the black strip on the chart. The black strip
indicates that there is a circuit between the terminals whose numbers are shown on the left and
when white there is no circuit.
Look at Figures A and B as examples. Actuator type used for test is the linear Cam travel type
(b) shown left. The start point is at the arrow marked ‘‘A’’ (See fig. B). This shows the free posi-
tion to be 5.3 mm from the vertical center line of the unit. At this stage there is a circuit between
the terminals 2122 but no circuit between terminals 1314. The unit can be actuated until it
reaches the operating position which is 10,5 mm from the center line – a travel distance of 10,5
– 5,3 = 5,2 mm from the free position. At this point the circuit arrangement changes – no circuit
between 2122 but making a circuit between 1314. If, however, the contacts of terminals 2122
weld together and will not separate, a mechanical safety feature will take effect if the switch is
travelled past the point from which positive opening is assured, 13,9 mm. As the switch returns
it reaches the release position at 8,9 mm from the center line. The circuit will change back to the
original state and the difference between the operating position and the release position gives
what is known as the differential travel i.e. 10,5 – 8,9 = 1,6 mm. The asterisk (*) indicates the
point from which the positive opening is assured.
