The Primus Windpower 2-ARAC-101 3-Position Stop Switch is recommended as an easy method for shutting down both Air Breeze and Air X Turbines (a switch is included with each new Air Breeze turbine). This super heavy duty switch is "triple sealed" with a flexible acrylic coating, T5 clear vapor seal and a toggle boot cover.brbrThe DC rated 50 amp switch allows you to "stop" the turbine. The switch first disconnects the battery and then shorts the turbine output wires together causing the turbine to stop spinning (in high winds the blades may spin slowly). Shorting the turbine does not cause any damage or additional wear on the unit.brbrul li1.1" Chrome Lever/li liZinc Die Cast Metal Body/li li#8 Screw Terminals/li li.5" Diameter Mounting Hole/li/ul
