It is the genuine Tecmark part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow an air switch is used\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eAir switches let a bather start a pump or a blower without any electrical connection at the button. Pressing the button sends a pulse of air down a small tube to the switch, which sits back at the equipment. The diaphragm inside moves and closes the circuit. Because only air travels to the button, there is no line voltage anywhere the user can reach.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBefore you order\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eMatch the configuration to what the equipment needs. This one is SPNO, single pole and normally open, so it closes a single circuit when actuated. If your panel uses a different pole or contact arrangement, a different Tecmark switch is required.\u003c\/p\u003e","brand":"Tecmark","offers":[{"title":"Default Title","offer_id":48634972176596,"sku":"TDI-851-0339","price":23.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_3cdecf87-416c-4ad2-9f4d-e71e48feb47e.jpg?v=1788839239","url":"https:\/\/www.activepoolsupply.com\/products\/air-switch-1","provider":"Active Pool Supply","version":"1.0","type":"link"}
