That left\/right detail is important for installers and service techs working inside tight control cabinets where physical clearance and wire routing matter. Application-wise, SPDT auxiliaries are excellent for interlocks, alarm logic, and controller inputs where you want one clean “on\/off” state without tapping the power circuit. You can use it to provide a single status point to BAS, to flip a control signal between two modes, or to enable a downstream function only when the primary contactor is engaged. Because it includes both NO and NC behavior via a common terminal, it reduces guesswork during retrofits. It’s part of the A2L‑compliant auxiliary lineup intended for use with compatible contactors, supporting modern HVAC\/R builds and replacements.","brand":"Mars","offers":[{"title":"Default Title","offer_id":67778877456751,"sku":"61604-ROC","price":126.8,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0958\/4335\/2943\/files\/61604-aux-20e4ce4c.png?v=1792147911","url":"https:\/\/www.rsl.ca\/products\/mars-auxiliary-a2l-1-no-910-780-7596-61604-roc","provider":"RSL.ca","version":"1.0","type":"link"}
