The momentary action makes it ideal for start\/stop type control circuits or any application that requires a temporary closing contact to energize a function, then return to the open state after release.\u003c\/p\u003e \u003ch3\u003eIdeal use cases\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eRetrofit projects where equipment expects the 800T-T4T8 form factor and contact behavior, enabling seamless part swaps without redesigning panels.\u003c\/li\u003e \u003cli\u003eLegacy control panels undergoing modernization, preserving wiring compatibility and shutdown safety sequences.\u003c\/li\u003e \u003cli\u003eMaintenance planning where keeping a single, consistent part number simplifies stocking, ordering, and service workflows.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eHow it integrates into your control system\u003c\/h3\u003e\n\u003cp\u003eThe 800T-T4T8 provides a straightforward momentary, normally open contact suitable for manual control and switching functions. When pressed, it closes the circuit to actuate a function; when released, the contact reopens, returning the circuit to its idle state. This predictable behavior supports reliable start\/stop logic and quick testing of control loops without lasting engagement.\u003c\/p\u003e \u003ch3\u003eSupport and compatibility\u003c\/h3\u003e\n\u003cp\u003eIf you need help matching a part number or confirming compatibility with your equipment, AmpState is ready to assist. \u003cstrong\u003eMessage us and we’ll help you confirm fit.\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/div\u003e","brand":"AmpState","offers":[{"title":"Default Title","offer_id":46410899325090,"sku":"800T-T4T8","price":10.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/8094\/6850\/files\/allen-bradley-800t-t4t8-switch-momentary-normally-open-ampstate-233.webp?v=1788986728","url":"https:\/\/www.ampstate.com\/products\/allen-bradley-800t-t4t8-switch","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
