The difference makes the difference - Push Button/Switch Often, push buttons and switches are used as synonyms. Although both are operated to control the flow of electricity, a push button is not a switch and vice versa. A switch retains its position after being activated and locks in place. A push button returns to its original position, serving only as a momentary activator. Capacitive switches/push buttons Click/Clack - this is the sound we imagine a switch makes when activated. However, this is not ideal for all applications: Mechanical switches/push buttons with a travel mechanism always have a gap between the housing and the actuator due to technical reasons. This can allow water and dirt particles to enter in both outdoor and indoor applications, which is absolutely undesirable. Additionally, the moving parts of mechanical push buttons lead to wear and tear, which is something that industries want to avoid as much as possible. Special feature: capacitive.
