Short-strike microswitch - has leaf spring connected to end of contact lever opposite to that carrying stroke limiter

摘要

Increased sensitivity of the microswitch is achieved with the reduction of the differential stroke in the moving contacts operating mechanism. The insulating base holds the fixed contacts, and the selective commutation of the moving contact is ensured by the series connection of the drive lever, intermediate lever, leaf spring and the contact carrying lever. The latter as well as the drive lever are pivoted on the insulating base, while the ends of the intermediate lever and of the leaf spring are interlinked and bear against the motion abutment. The leaf spring is connected to the end of the contact lever opposite to the end which holds the moving contact, and the centre of the lever is connected to the base. In addition to the articulation of the contact lever (9) on the insulating base (1), it is connected to the end (15) of the leaf spring (S) which is tied to the intermediate lever (7). The free end of lever (9) carries the stroke limiter (17) controlling the end (13) of the intermediate lever (7), and the connection of lever (9) to the base is between moving contact (4) and the joint of lever (9) with the leaf spring (7).
