Application
KW3A micro switch which is a basic micro switch features higher current and higher temperature selection compared to other micro switches. Adaptable to a variety of household appliances, it is widely used in microwave ovens. Not only does it act as a main power switch, but it can also act as a door control switch, which is very powerful.
The KW3A micro switch also has a larger current selection range and can carry a larger current, so it is very convenient to use in some high-power household appliances. In addition, its high-temperature selection range also makes it difficult to damage in high-temperature environments, more durable and reliable.
