It is designed for panel mounting and pairs with standard 800T contact blocks such as the 800T-XA, enabling straightforward wiring of normally open and normally closed configurations in control circuits. Part of Allen-Bradley’s 30 mm selector switch lineup, the 800T-H4 fits within the broader 800T\/800H ecosystem, supporting common accessories and replacement parts for reliable, long-term panel integration. Typical applications include operator-initiated signals in machine control, such as start\/jog\/reset or select inputs in automation systems, where a momentary input is required to trigger a PLC or relay logic.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51657275081006,"sku":null,"price":36.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_2bb8d69e-6074-458a-bf8e-ccef3040c3a4.jpg?v=1769467433","url":"https:\/\/plgautomation.com\/products\/allen-bradley-800t-h4-momentary-selector-switch","provider":"PLG Automation ","version":"1.0","type":"link"}
