MWK-3 Series

MWK-3 Series Aviation & Military Micro Switch

1. Small size, light weight, large load capacity;
2. With instantaneous action function, the action is sensitive and the parameter accuracy is high;
3. The contact system of the entire switch is enclosed in a metal shell, which is an airtight micro switch;
4. Electrical life up to 10,000 to 12,000 cycles.
