## Product: iVac Pro Switch S11520NA
**Brand:** iVAC

## Pros
- Works exactly as advertised and suits its intended application well, especially for automating dust collection in workshops.
- Offers advanced features like automatic dust collector activation based on power sensors and blast gate control, improving convenience and energy savings.
- Supports a highly expandable system for remote start automation, allowing future upgrades and customization.
- High manufacturing quality that surpasses many competitors in durability and reliability.
- Responsive and excellent online customer support helps navigate programming challenges.
- The amperage rating is accurate and clearly labeled for typical dust collection motors (1.5 HP), alleviating earlier concerns about underestimated current capacity.
- Automatically turns dust collector on/off with CNC routers or similar tools, helping reduce power costs and improve workspace cleanliness.
- Functions reliably in single-unit setups and effectively boosts signal when used individually.

## Cons
- Programming the switch can be somewhat challenging, especially initially.
- Relay contacts can fail quickly under high startup current or inductive motor loads, leading to welded contacts.
- Not suitable for direct use with inductive motors like 1.5 HP dust collectors without an additional contactor; iVac recommends adding a contactor to protect the switch.
- Accessories such as remotes required for full functionality are sold separately and can add up in cost.
- Using multiple units in close proximity causes signal interference, so spacing units apart is necessary for best performance.
- Warranty replacements require proof of purchase and are contingent on the buying source, adding some hassle if purchased through third parties.
- Does not work out-of-the-box with magnetic switch dust collectors and may require electrical modifications or a different model for compatibility.
- Some negative reviews result from misunderstanding the setup requirements and motor load limitations described by iVac.

## Bottom Line

The iVac Pro Switch 115 Volt - 20 Amp #S11520NA is a solid choice if you want a rugged, expandable automation solution for your dust collection system and are willing to invest some time in proper setup and accessories. However, it is *not* a simple plug-and-play for inductive motor loads like 1.5 HP dust collectors without adding a contactor for protection. If you want a model designed to handle 1.5 HP motors directly, consider looking for the newer S11520-A-NA version, which addresses this limitation more gracefully. Overall, this switch shines in reliability and flexibility but demands careful planning and possible extra investment on your part to get the most out of it.
