The unit pairs a round selector actuator with a keyed cylinder lock, enabling the switch to be locked in one of two positions to prevent unauthorized or inadvertent changes to machine mode. Its spring-return mechanism ensures the actuator returns to its default state when released, delivering predictable standby behavior in control circuits. As part of the 800MR family, the H48B variant identifies the cylinder-lock option within the two-position MR selector lineup, aligning with Allen-Bradley’s approach to securing critical transitions such as run\/manual or auto\/manual modes. Typical applications include start-up sequencing, mode selection on packaging lines, conveyors, and presses, where restricted access to mode changes enhances safety and process control. This device is designed for robust, field-serviceable performance in standard industrial environments, offering the reliability associated with Allen-Bradley hardware while delivering straightforward, mechanical control of two discrete states.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":51657511928110,"sku":null,"price":43.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_7305d41c-6e7f-4422-b1e8-a7da1e8f2b5b.jpg?v=1769469721","url":"https:\/\/plgautomation.com\/products\/allen-bradley-800mr-h48b-cylinder-lock-selector-switch","provider":"PLG Automation ","version":"1.0","type":"link"}
