All of these signalling systems are
C C hand resettable and fitted with silver-
2 1 2 1
NC NC plated 3-terminal microswitch C, NO
and NC.
NO NO
4 4 The C terminal is on the top and
connection is made via 6.35 mm
Non-blown fluse Blown fluse clips except for watertight models
Microswitch ON Microswitch OFF
NOTE (2): The 26.4 dimension is the same with whose clips are 4.8 mm wide.
1 or 2 separated circuits NO-NC.
Tests with sine vibrations carried out at ambient with scanning of the three main holder axes.
Spectrum: 1st segment (2 to 16 Hz) constant trip x = 5 mm peak.
2nd segment (16 to 250 Hz) constant acceleration g = 5 g peak.
Exponential scanning speed : 1 octave per minute.
Duration: 2 hours per axis.
