Notes for Turquoise Switches (BJ, BS, BV type)
• Dust protection test
Test conditions: The talcum powder used shall be able to pass
through a square- meshed sieve the nominal wire diameter of 7
μm. The amount of talcum powder to be used is 2 kg per cubic
metre of the test chamber volume. The duration of the test is 8
hours.
No damage observed after the test.

■ Oil-proof and chemical-proof characteristics
The rubber elastomer swells when exposed to oil and chemicals.
The extent of swelling will vary widely depending on the type and
amount of oil and chemicals.
Check with the actual oil or chemicals used.
In particular, be aware that solvents such as freon, chlorine, and
toluene cannot be used.
■ Washability [ABJ (BJ) and ABS (BS)]
Do not clean the switch. Doing so can cause problems. Please
contact us if cleaning is necessary.

REFERENCE
■ Dust-protected type
This type of construction prevents dust that is large enough to
have an effect on operation from getting inside the unit. This
construction is stipulated by protective classes against solid
matter in the IEC standards (IEC60529).
The talcum powder used shall be able to pass through a square-
meshed sieve the nominal wire diameter of 7 μm. The amount of
talcum powder to be used is 2 kg per cubic metre of the test
chamber volume. The duration of the test is 8 hours.
No damage observed after the test.
■ Immersion-protected type
This type of construction prevents any harmful effects even after
the device is left underwater at a depth of 1 m for 30 minutes.
This construction is stipulated by protective classes against
water in the IEC standards (IEC60529).
■ IEC’s IP Codes
The IEC (International Electrotechnical Commission) has
defined the IP characteristic code that represents the levels of
protection described in IEC standard (IEC60529).
The two numbers that follow the IP code (the characteristics
numbers) indicate the suitability of this protection for all
environmental conditions.

1st characteristics number
2nd characteristics number
