Part Numbering: The document provides a detailed part numbering system to identify the specific configurations of the switches, including actuator shape, bracket style, number of poles, and terminal style.

Mounting and Soldering Instructions:

Manual soldering: Use a soldering iron at 380℃ max for 3 seconds max.
Auto soldering: Use jet wave or dip type at 275℃ max for 3 seconds max.
Pre-heating should be below 100℃ and within 30 seconds.
Use PC boards with a hole diameter of 0.8mm.
Do not bend terminal pins before mounting.
Avoid applying excessive load on the actuator.

Cleaning Instructions:

Use fluorine or alcohol-type solvents.
The BT series switches are not washable; clean the soldering surface with a brush.
Ensure terminal temperature is below 90℃ before cleaning.

Optional Accessories: Color caps in round and square types are available in white, red, black, and gray, sold separately.
