What is the difference between a microswitch and a tact switch?

A microswitch and a tact switch are both types of electrical switches used for different applications due to their distinct designs and operational characteristics. Here’s a detailed comparison highlighting their differences:


Design and Operation:

  • A microswitch, also known as a snap-action switch, operates based on a tipping-point mechanism.

  • It typically has a small lever or button that, when actuated, causes a rapid "snap" movement of internal contacts.

Actuation Force:

  • It requires a relatively small force to actuate, but the force must be applied in a precise manner.

  • The actuation point is highly consistent, making it reliable for repeated operations.

Durability and Lifecycle:

  • Microswitches are known for their durability and long operational life, often rated for millions of cycles.

  • They are built to handle high loads and frequent use.


  • Commonly used in devices where precise, reliable, and rapid switching is crucial, such as in safety mechanisms, appliances, industrial controls, and automotive systems.

Tact Switch:

Design and Operation:

  • A tact switch, or tactile switch, is designed to provide a noticeable tactile feedback (a "click") when pressed.

  • It generally has a smaller form factor and is often surface-mounted on a PCB.

Actuation Force:

  • Tact switches require a moderate force to press, and the tactile feedback helps users know when the switch has been activated.

  • The actuation force can vary, but it is typically consistent within a specific switch model.

Durability and Lifecycle:

  • Tact switches have a shorter operational life compared to microswitches, often rated for thousands to tens of thousands of cycles.

  • They are suitable for low to moderate usage applications.


  • Commonly used in consumer electronics, remote controls, keypads, and other devices where user interaction is less frequent and less demanding than in industrial settings.

  • Microswitches are robust, precise, and designed for high-load, high-frequency applications. They offer long life and consistent performance.

  • Tact switches provide tactile feedback, are compact, and are suitable for lower-load applications where user interaction requires feedback but not necessarily high durability.

Choosing between the two depends on the specific requirements of the application, such as the need for durability, tactile feedback, size constraints, and the frequency of use.
