PRESENTATION
This is the basic comporent for our whole range of standard 1-pole and 2-poIes hermetically-sealed limit swit-
ches plus the 3-poIes version (special Umit Switches).
The CROUZET hermetic microswitch combines a snap-action switching system with high resistance to shock
and vibration in an hermetically sealed miniature case which encloses an atmosphere of inert gas around its
contacts, ideal for switching very Iow level circuits and higher currents also.
The meticulous care taken in the manufacture of this hermetically sealed cell in terms of assembly processes,
cleanliness of components as well as inspection procedures, result in a product which is ideal for operation in
severe environments where a high level of reliability is essential.
The CROUZET hermelically sealed cell is particularly well suited to sectors such as Aerospace, Armaments,
Marine, Nuclear, etc.

Hermetic sealing
• The microswitch is fi lled with inert gas (nitrogen-hydrogen mixture), the internal pressure being 1 bar.
• The hermetic sealing (membrane-cap - cap-base) is achieved with a continuous seam welding bead.
• 1 x 10-8 atm cm3/s

Mechanical strength
No abrupt increase in the total travel of the
device is noted under rising overtravel forces
of up to 80 N. On return to a normal overtravel
force of 20 N after these measurements have
been carried out on one and the same device, the
total travel will be observed to have varied only
very little (low permanent set).
The device can be damaged if the overtravel
force is pushed up to 150 N.
Change in operating force as a function of
ambient temperature and pressure.
The force values of our hermetically sealed
microswitches are infl uenced by ambient pressure
and temperature; we give the value, for the base
cell, for the increase in operating force (∆ OF) as a
function of these two parameters.
The characteristics are stated for normal
temperature (23°C) and atmospheric pressure at
sea level (760 mm Hg).
Our hermetically sealed microswitches can be used
from atmospheric pressure to absolute vacuum;
some variants allow use at higher pressures.

SP 48-16 sensitive switches
Dear Sirs
Please fi nd enclosed two copies of the reports on the tests to which we have subjected your SP
48-16 sensitive switches.
These tests demonstrated that the hermetically sealed cell 83 151 506 (6 bar) satisfi ed the opera-
ting and environmental conditions (especially in accidents) required for K1 safety equipment.
However, they have led to modifi cations being made to the connection method and control system:
- single-wire connection with STYCAST 2651 resin fi ller/Catalyst 9
- stiffener on the operating lever to reduce the sensitivity to vibrations with extension of this lever to
reduce the actuating force
Yours faithfully

1 – SUBJECT
Tests were conducted to determine the withstand to GAMMA rays (integral dose of 10 rads) of
CROUZET microswitch type electrical components (hermetically sealed cells) that might be
suitable for installing in the irradiated component cell of the PHENIX reactor, a 100 kilocurie
α – β – γ type cell.
2 – CHARACTERISTICS OF HERMETICALLY SEALED CELLS BEFORE IRRADIATION
These hermetically sealed cells are fully sealed microswitches, fi lled with inert gas (hydrogenated
nitrogen) at a pressure of 1 bar.
Part number: 83-151-001

3 – OPERATING CONDITIONS OF HERMETICALLY SEALED CELLS
In the irradiated component cell of the PHENIX reactor:
- Atmosphere: Nitrogen with 2% max. oxygen content
- Pressure: 2 mbar
- Temperature: 50ºC approx.
- Relative humidity: 2% max.
- Maximum dose rate: ≤ 5.105 R/hr
4 – IRRADIATION (test conditions)
- Date: from 15/03/1972 to 10/04/10972
- Place: PAGURE cell (CAPRI) at C.E.N./SACLAY
- Source: 20,000 curies of cobalt 60 – consisting of 10 bars of 2000 Ci
- Atmosphere: Air
- Pressure: Atmospheric
- Temperature: 20ºC approx.
- Relative humidity: 60% approx.
- Exposure dose: 1.078 109 rads
- Dose rate: 2.2 106 R/hr
- Duration: 490 hrs
- Distance: in basket no. 2 (at the heart of the source)
- Integral dose: almost equivalent to the exposure dose, ie. 1.078 109 rads.
NB: During its irradiation with γ rays, no endurance tests were conducted.

6 – CONCLUSION
The test results highlight that the characteristics of the hermetically sealed cells have not
undergone any signifi cant change and that they are suitable for the operating conditions of the
irradiated component cell in the PHENIX reactor.
However, it should be noted that no endurance tests were conducted with γ ray fl ux.
