Micro Switch With CUL

2.5.1

Cold

The switch should be tested at -40±2℃ for 96 hours. After the testing period, it should be allowed to rest in a normal room temperature and humidity environment for 1 hour. Within 1 hour of resting, measurements must be taken, ensuring that any water drops are removed.

Contact resistance(item 4.1):

100mΩ MAX

Insulation resistance (item 4.2):

50MΩ MIN

Voltage proof: (item 4.3)

No dielectric breakdown shall occur.

Operating characteristic (item 5.1):

A wide range of operating characteristics falls within a ±10% tolerance of the specified value. To create a highly similar content, the above information can be rearranged as follows: "The operating characteristic variety encompasses a tolerance range of ±10% around the specified value."

Appearance and construction must exhibit no irregularities or anomalies.

2.5.2

Dry heat

During the 96-hour test at 105±2℃, it is required that the switch remains in normal room temperature and humidity conditions for 1 hour before conducting any measurements within the following hour.

2.5.3

Damp heat

After subjecting the switch to a 40±2℃ temperature and 90-95% relative humidity (RH) for a duration of 96 hours, it is necessary to allow the switch to remain undisturbed under normal room temperature and humidity conditions for a period of 1 hour. Following this, measurements must be taken within 1 hour of the switch being removed from the test environment, ensuring that any water drops are carefully eliminated.

2.5.4

Change of

temperature

After 20 cycles of following conditions the switch shall be allowed   to stand under normal room temperature and humidity condition for 1h, and   then measurement shall be made within 1 h. water drops shall be removed.

2.5.5

Salt mist

Switch shall be checked after following lest.

1) Temperature: 35±2℃

2) Salt solution: 5±1% (solids by mass)

3) Duration: 24±1h

After test, salt deposit shall be removed in running water

No remarkable corrosion shall be recognized in metal part

2.6.2

Resistance to soldering heat

The switch will be inspect under such conditions   below

          Temperature and impregnated time

All of the appearance, motor functions, electrical   properties are no abnormal.
