In addition, pay careful attention to use the solvent. （2）The cleaning method is limited to immersion cleaning only. The cleaning time is 2 minutes, max, but be sure to minimize the time as much as possible. （3）To clean the switch after soldering, wait until the switch temperature has cooled down to room temperature (30℃ or below). （4）The product must be dried sufficiently after cleaning. Improper drying may result in fluctuation in torque or electrical damage.
