Abstract
The electric switching apparatus assembled of a plurality of consecutively arranged modular units, includes snap action arresting means integrally formed on opposite side walls of each unit. The arresting means includes frame-shaped resilient arresting pieces leveled with the upper surface of the assigned side wall and being at one edge thereof integrally connected thereto and cooperating with matching arresting points on the adjoining unit.
Claims14
An electric switching apparatus, particularly a cam switch including a driving unit, a detent chamber unit, and at least one switch chamber unit, said units having a modular construction and being consecutively arranged in axial direction one after the other, comprising snap action arresting means integrally formed on opposite side walls of each unit and including on respective side walls resilient arresting pieces, and rigid arresting points, said points on one unit being releasably engageable with the arresting pieces in the adjoining unit, and recesses formed in said side walls of respective units opposite the free edge of each arresting piece to accommodate a screwdriver-like tool for lifting said arresting pieces during the disassembly of respective units, said side walls in each unit being asymmetrically staggered relative to each other to define a central step for preventing angular displacement of said unit.
An electric switching apparatus, particularly a cam switch including a drying unit, a detent chamber unit and a plurality of switch chamber units, said units having a modular construction and being consecutively arranged in axial direction one after the other, comprising snap action arresting means integrally formed on opposite side walls of each unit and including on respective side walls resillient arresting pieces and rigid arresting points, said points on one unit being releasably engageable with the arresting pieces in the adjoining unit, each of said plurality of switch chamber units having staggered lateral sides of its housing interconnected by resilient arresting pieces engaging rigid arresting points on the adjoining unit, the chamber unit being coupled to said driving unit by means of yokes provided on the top and bottom sides of the detent chamber unit and engaging angular projections on said driving unit, and each of said switch chamber units having binding posts arranged on its top and bottom sides.
