Rotary drive for lever-operated switchgear module - has input spindle with segment gear engaging rack on moving element to transmit motion to other spindles

摘要

A lever operated switch has a box shaped housing (60, 80) with a lever coupled to a spindle (12). The lever has an integral segment gear (6) that meshes with a formed gear rack (54) in a switch actuator element (50) that can move within the housing. The actuator element has additional racks (56,58) formed on the outer walls and these are engaged by further segment shaped elements (20, 30) with spindles that project from the main housing. When the input spindle is moved by the lever, rotary motion is transmitted to the side spindles. These may connect to the other switch modules. ADVANTAGE - Improved connection possibilities for operating switchgear.
