The maximum current rating of a micro switch, also known as a snap-action switch or miniature switch, can vary depending on the specific make and model. Generally, micro switches are designed to handle low to moderate levels of electrical current, typically in the range of 5 to 15 amps.
However, some micro switches may be rated for higher currents, up to 20 or 25 amps. It's important to consult the manufacturer's specifications to determine the maximum current rating of a specific micro switch before using it in an application.
It's also important to note that the current rating of a micro switch is only one factor to consider when selecting a switch for a particular application. Other factors to consider include the voltage rating, operating force, mechanical life, and environmental conditions, among others.
