Schneider Electric CSW110BPR-GY Switch is a device used to interrupt or divert the flow of electric current in a circuit. It can be manually operated (like a light switch) or automatically operated (like a sensor-triggered switch). 10A is the maximum current the switch is rated to handle safely. 

250V is the maximum voltage the switch is designed to handle. 1G is the number of gangs available in the switch. A gang in this context usually means the number of independent circuits the switch can control. The switch has both momentary and alternate action capabilities.

Momentary action means that the switch returns to its default position when released, while alternate action means it toggles between positions. IP66 is an Ingress Protection (IP) rating. It is dust-tight, providing complete protection against contact. It is protected against powerful jets of water from all directions.

In summary, the Schneider Electric CSW110BPR-GY Switch is a 10A, 250V switch with 1 gang, capable of both Momentary and Alternate action, and it has an IP66 rating, indicating high levels of dust and water resistance. This type of switch might be used in outdoor or industrial applications where it's exposed to harsh environmental conditions.
