Manual switch for a mechanical time-switch clock

Abstract

The invention relates to a mechanical time-switch clock with a rotary driven duplex star wheel (20) having two ratchet-tooth gears with ratchet-gear teeth (22) and (24) arranged in axial sequence.  Furthermore, the time-switch clock has a contact spring set with a middle (52) and two outer contact springs (51 and 53).  For automatic switching of the contact spring set, two rotary switch levers (1 and 2) are provided which alternately are engaged with the contact springs (51, 52, 53) of the contact spring set.  For manual switching of the contact spring set, the invention provides that a manually rotatable control lever (35) which can be moved from a neutral, middle position into a first and into a second switch position, is provided for the contact springs (51, 52, 53) and for the second switch lever (2).  By means of the control lever (35) the second, middle contact spring (52) in the first switch position can be brought into permanent contact with the third, outer contact spring (53) and simultaneously is disconnected from the first, outer contact spring (51).  In the second switch position, the second switch lever (2) is adjustable by the control lever (35) so that the third, outer contact spring (53) is separated from the middle contact spring (52) and the first, outer contact spring (51) is in a permanent contact with the second, middle contact spring (52).

Description

technical field [0001] The invention relates to a mechanical timing switch, which has: [0002] Double switching star wheel drivable in one direction of rotation, with a first switching ring gear with teeth of a first switching ring gear and a second switching ring gear with teeth of a second switching ring gear, wherein the second switching ring gear A switch ring gear and a second switch ring gear are arranged in sequence along the axial direction, the teeth of the second switch ring gear are staggered by half a tooth pitch relative to the teeth of the first switch ring gear, [0003] A contact spring group, the contact spring group has an outer first contact spring, a middle second contact spring and an outer third contact spring, the contact springs of the contact spring group are spaced apart from each other and extending substantially parallel to each other, [0004] A rotatable first switch lever, which engages with the first switch ring gear and by means of which the...

Problems solved by technology

Here, in systems with double switching starwheels, there is the difficulty that the switching system has to be engaged in such a way that after returning from normally-1 (normally open) or normally-0 (normally closed) to automatic The switching state set via the switch panel is re-identified and assigned at runtime
