Snap action switches, also called microswitches, are switch devices that can open and/or close an electrical circuit at a rapid speed. Triggered by an external force, either human or physical object, which is then applied to the actuator, requiring very little pressure to operate. They are characterized by their quick and decisive switching action, often producing a sharp “snap” sound when the contacts move from one position to another.
Reliability and long operating life make these switches ideal for many applications and devices, but what are the best snap action switches for 2024 markets?
