At the far end, inside the equipment pack, that pressure pulse trips this switch, and the switch is what actually makes and breaks the circuit to the pump or blower. Keeping the electrical switching at the pack and away from the water is the whole point of the design.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen it fails\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eAir switches see thousands of cycles and are usually the first thing in the chain to give out. Before condemning the switch, check the air tube from the button. A tube that is split, pinched or holding water will stop the pressure pulse getting through and produce exactly the same dead button.\u003c\/p\u003e","brand":"Tecmark","offers":[{"title":"Default Title","offer_id":48634967982292,"sku":"TDI-851-0310","price":22.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_934fd402-c10a-4414-b2b6-05d254681a74.jpg?v=1788839162","url":"https:\/\/www.activepoolsupply.com\/products\/air-switch","provider":"Active Pool Supply","version":"1.0","type":"link"}
