Green DS-429A 10MM 2PIN Self-Locking Square Push Button Switch with Lock

Push buttons are simple switches that control the power of a machine or device. They are usually made of metal or thermoplastic and are designed to provide easy access to the user. They are commonly used in controller panels, push-button telephones, kitchen appliances, magnetic locks, and many other mechanical and electronic devices in homes or industries.

Electric circuits work by allowing electricity to flow through wires and components without interruption. However, some circuits are more useful when they can be turned on and off as needed. This is where push buttons come in handy. They can complete or break a circuit with a simple press.
