An electrical contact is an electrical circuit component found in electrical switches, relays, connectors and circuit breakers. Each contact is a piece of electrically conductive material, typically metal. When a pair of contacts touch, they can pass an electrical current with a certain contact resistance, dependent on surface structure, surface chemistry and contact time; when the pair is separated by an Web4 de ago. de 2024 · NO and NC, and Other Proximity Sensor Basics.

The middle pin is always connected to the pin on the right [NORMALLY CLOSED], whenever the relay is turned on this middle pin is connected to the pin on the left [NORMALLY OPENED]. You should definitely test this using a multi-meter. I remember buying a relay module from a Chinese vendor and this drawing was wrong ! WebConversely, if a button usually acts like a short circuit unless actuated, it’s called a normally closed (NC) switch. NC switches are “push-to-break”; actuating the switch creates an open circuit.
