Rotary stepping switch latching mechanism - has spherical locking member on switch axis coacting with latching collar in housing

摘要

The latching mechanism is intended for a rotary stepping switch with variable rotary range limiting and spring resetting. A stopping strip cooperates with angular stops secured to the switch housing. The switch axis carries a present resetting wound spring in axial direction next to the spherical locking member. This spring is further stressed by the switch axis rotation from a present switching position, being released when the switch axis is delocked. The switch housing is divided into two parts, having in the first part a deep set latching rim, and in the second part circumferentially distributed grooves, corresponding to the switching positions. These grooves are engageable by the sprung stop, onto which abuts one end of the wound spring supported by the housing.
