What is a Dust Collector Switch Box?

In this video, Calvin shows viewers how to install automated dust control on his table saw using the iVAC model Switch Box and Contactor. He also provides detailed explanations on how motor controller contactors operate and how to wire them in 240 volt circuits.

Does anyone know if it's possible to have both an auto start with the remote switch?

Hello BNS Software. I forwarded your question to iVAC for a response. I do believe they have a product that will do what you need and you can check their website at www.ivacswitch.com to get a full explanation of their products and how to incorporate them into a system that works for you. Tom from iVAC said you can also send your questions to [e-mail] and he will answer directly.

Nice video. Is there any difference between a contactor and a relay aside from the size?

[@brashair7652]

The biggest difference is size in that a contactor is designed to handle higher current and the contact points are usually made of a more durable material. Also the cores in smaller relays are typically round armatures whereas contactors typically have “E” type laminated core windings similar to what you would see in an AC transformer. Also you’ll probably see more DC relays than AC relays and more AC contactors. The AC windings have a shaded pole to assist with offsetting the phase, and combined with the natural eddy currents in the winding will magnetically hold the contactor closed (assuming NO type contactor) when the AC phase changes direction.
