旋转开关,因为其用途的关系,整体采用密封结构,有一定的防水效果,基本可达到IP65的防水级别。
同时需要采用比较坚硬耐用的金属材质,在档位上有2档或者3档的区别。如AS系列(RIVERSUN (HONG KONG) LTD ):
Electrical Ratings 1A @ 24VDC;1A @ 125VAC;0.5A@ 250VAC
Dielectric Strength 2000Vrms min contact to contact
Insulation Resistance ≥ 100MΩ min
Operating Temperature -25ºC to 55ºC
Sealing Degree IP65 standard
Storage Temperature -25ºC to 55ºC
Electrical Life 50,000 cycles typical
Contact Resistance ≤50mΩ initial
