tastschalter

Tastschalter, also known as push-button switches, are electrical switches operated by a user pressing a button or lever. When pressed, the switch causes a temporary change in the electrical circuit, typically completing or breaking it. Upon release of the button, the switch usually returns to its original state, either through a spring mechanism or by the nature of the circuit. This momentary action is a key characteristic distinguishing them from latching switches, which remain in their activated state until pressed again.

These switches are ubiquitous in electronic devices and everyday applications. They are commonly found on keypads of calculators and remote controls, for starting and stopping motors in appliances, and as reset buttons on various electronic equipment. Their simplicity of operation and relatively low cost make them an ideal choice for many control interfaces.

Tastschalter come in various forms, including tactile switches, which provide a distinct physical and audible click to confirm activation, and non-tactile versions. They can be designed for surface mounting on printed circuit boards or for panel mounting in enclosures. The electrical contacts within a tastschalter can be configured as normally open (NO), where the circuit is closed only when the button is pressed, or normally closed (NC), where the circuit is open when the button is pressed.
