A-2-B switch, type 0910 For limiting the hoist height BROSA A-2-B switches prevent the hook block or load hook to be pulled against the boom head. During the operation a suspended weight keeps the A-2-B switch contact closed. The uplifting of the suspended weight will open the contact only when the hook block has reached the maximum admissible position. The A-2-B switch is characterised by its corrosion-resistant light metal housing and the completely casted electronic functional parts. Two resistors are installed to control the feed lines. An optional suitable counterweight is available. Applications • Cranes • Lifting technology Features • Easy assembly • Corrosion-resistant housing • Positively driven end switch
