Important Parameters Of Waterproof Micro Switch

1. Anti-leakage index: It is the maximum withstand voltage value that inserts 2 electrodes into the test product and drops 50 drops of the specified solution (ammonium chloride 0.1[%]) between the electrodes without short circuit. There are the following 5 types grade. The relationship between the CTI value and PTI of the UL Yellow Book is shown in the following table.

2. Number of operations: indicates the number of times of switching in the durability test specified in the specifications. Each manufacturer chooses from the number of times in the table below, which is indicated by a symbol on the switch. In the IEC specification, the switch standard for high-frequency operation is 50000 times, and the switch standard for low-frequency operation is 10000 times.

3. Operating environment temperature: the temperature range that the switch can use. Please refer to the following for the meaning of the symbols:

Representation symbol T85 25T85

Temperature 0~+85℃ -25~+85℃
