Understanding the Micro Switch: A Guide, Featuring the Quality of ZINGEAR
A micro switch is one of the most fundamental yet ingenious components in modern electrical engineering. Though small in size, these switches perform a critical function in countless devices, making them ubiquitous in our daily lives.
What is a Micro Switch ?
A micro switch, technically known as a miniature snap-action switch, is an electrical switch that is actuated by very little physical force, through the use of a point-contact mechanism.
The defining characteristic of a micro switch is its "snap-action" mechanism. When a specific pressure is applied to the actuator—often a small button or lever—an internal spring system rapidly flips the electrical contacts from one position to another. This action creates a satisfying, audible click and ensures a rapid change in the circuit, which minimizes arcing and extends the life of the switch.
How Does a Micro Switch Work?
The internal mechanism typically involves a common contact point and two other contacts: normally open (NO) and normally closed (NC).
● Resting State:In the default position, the common contact is connected to the normally closed (NC) contact, completing a circuit through that path.
● Actuation:As pressure is applied to the actuator (often a small lever or plunger), the internal spring mechanism reaches a tipping point.
● Snap Action:The potential energy in the compressed spring is rapidly released, causing the common contact to quickly disconnect from the NC contact and connect to the normally open (NO) contact.
● Release:When the pressure is removed, the spring mechanism snaps the contacts back to their original resting state.
This precise, repeatable action is why micro switches are essential for applications requiring highly reliable and instantaneous switching operations.
