The 1658540-3 contact is a multi-purpose contact typically used in switches and relays. It is a mechanical device that closes and opens an electric circuit when the switch is operated. The 1658540-3 contact is a silver-plated, beryllium copper contact that is rated at 5A at 250VAC and 5A at 24VAC in power applications switch use. It is a single-pole single-throw (SPST) normally open contact, which means that when the switch is off, the circuit is open (off), and when the switch is on, the circuit is closed (on).

The 1658540-3 contact is available in both latching and non-latching versions. The latching version has a mechanical latch that holds the contact when it is closed, requiring manual resetting. The non-latching version does not have a mechanical latch, so it will return to the open position when the switch is released. This type of contact is typically used in high-load applications like heavy machinery, conveyors, and other industrial applications.

The 1658540-3 contact can also be used in less demanding applications such as vehicle lighting, cameras, sound systems, and security systems. Its high contact resistance and low voltage drop make it suitable for these applications. The contact is also highly resistant to corrosion, making it suitable for use in wet or humid environments.

The 1658540-3 contact’s working principle is simple. When the switch is operated, the contact closes, and an electrical current is allowed to pass through. When the switch is released, the contact opens and the current is blocked. The contact is designed to provide high contact resistance and low voltage drop, so that the switch can effectively control the amount of current flowing through the circuit.

In summary, the 1658540-3 contact is a multi-purpose contact suitable for various applications, including high-load applications, vehicle lighting, cameras, sound systems, and security systems. It is available in both latching and non-latching versions. Its working principle is simple; when the switch is operated, the contact closes, allowing an electrical current to pass through. Its high contact resistance and low voltage drop makes it suitable for these applications.
