What is a micro switch, and how is it different from an ordinary switch?
Published Time:

A micro switch (Micro Switch) is a highly sensitive mechanical switch that uses a snap-action mechanism, with an extremely small contact gap and very short travel. Unlike rocker/push-button switches, its traits are short travel, fast action, high reliability and long life—it can make/break precisely under minimal force, so it is widely used wherever precise position detection and safety interlock are needed. It is the invisible safety guardian hidden inside every appliance, vehicle and machine.
