Stack-type switch, has switching modules each with axle comprising upper shaft with toothed section and lower shaft with toothed hole, where upper shaft of one module is received in toothed hole of other module

摘要

The switch has switching modules stacked in series, where each module has a seat (10), connecting strips disposed in the seat, movable units received in the seat, and an axle (40) extending in a rotary manner across the seat to electrically connect/disconnect the strips. The axle has an upper shaft (41) comprising a toothed transversal section and a lower shaft (42) with a toothed hole. The upper shaft of one module is received in the toothed hole of the other module. The strips in the same line are electrically connected by conducting bars. Insulating bars are disposed on the conducting bars.
