Tact Switch

A tact switch, also known as a sensitive switch, is designed to activate when a specific operating force is applied. It enables on-off control by closing the circuit upon pressing and opening it once the pressure is released, ensuring momentary actuation.

The internal structure includes an insert, base, shrapnel, button, and cover plate. In waterproof models, a polyimide film is added to the shrapnel for enhanced protection against moisture, improving durability and reliability in challenging environments.
