For status detecting, signal generating or on-off control. Micro Limit Switch is mainly used for automotive, home appliances, new energy and industrial control. Typical application include different latching or detecting devices in automotive vehicles, appliances like dishwasher, ice maker, washing machine, refrigerator, coffee machine, vacuum cleaner, and etc.
Because of its snap action mechanism with small movement and rapid switching function. The word "micro" means small or tiny, so micro switch is small in size, whose normal length does not exceed 30mm; and the inner machanical structure is also in mini dimensions; not to mention the featured snap action mechanism accomplished by small but rapid switching movements.

Automotive industry, home appliances, new energy, industrial control and gaming control. For instance, lock system in cars, dishwasher, EV charging devices, automatic lubrication system, and mechanical keyboards.
A micro switch functions through a simple mechanism with three main parts: an actuator (like a lever or plunger), a spring, and electrical contacts. When the actuator is pressed or released, it moves the spring to a critical point where it snaps into a new position. This movement quickly changes the state of the electrical contacts inside the switch, either opening or closing them.
To test a micro switch, start with a visual inspection for damage or wear.
Use a multimeter set to continuity mode to probe across the switch terminals; it should show low resistance (closed circuit) when the switch is pressed and high resistance (open circuit) when released.
Operate the switch to confirm it audibly clicks and controls the device as intended.
