AK Series Aviation & Military Micro Switch

1. Large load capacity;
2. With instantaneous action function, the action is sensitive and the parameter accuracy is high;
3. Operating Temp.: (-55～85) ℃,  high-temp resistant products can reach up to 200℃;
4. The minimum Differential Travel range is 0.04mm max;
5. The electrical life can reach up to 10000-37000 cycles; the mechanical life of some products can reach up to more than 50000 times.
6. Auxiliary pressing mechanisms such as levers and rollers can be added according to user requirements, or they can be manufactured according to user-specified circuit structures.

Standard: AK type micro switch technical conditions (group Ⅰ) (internal) AK type micro switch technical conditions (group Ⅱ) (internal) AK1-3 micro switch technical conditions (internal) AK1-7, AK1-8 , AK2-7, AK2-8 precision micro switch technical conditions (internal)
