The 4-Element Switch, often referred to as a 4 Pole 4 Throw (4P4T) switch, is a versatile electronic component used in multi-layer printed circuit boards (PCBs). It features four electrical terminals that can connect or disconnect various parts of a circuit. When selecting such a switch, consider factors of the switch, voltage, current compatibility, size, actuation method, durability, and environmental suitability. Proper PCB layout and thorough testing are crucial when integrating this switch into your design to ensure reliable functionality in different switch positions and under varying conditions.

Attributes:
• Ensure it is a 4 Pole 4 Throw (4P4T) switch with four separate circuits
• Designed to handle particular current levels
• Consider the expected durability and lifecycle of the switch

Applications:
The 4-element Switch enables the controlled switching and connection of electrical circuits.
