用于机械式计时开关的手动开关
摘要：
本发明涉及一种机械式的计时开关，它具有能旋转驱动的双开关星轮(20)，所述双开关星轮具有两个沿轴向前后顺序设置的具有开关齿圈齿(22)和(24)的开关齿圈(21)。此外，计时开关具有触点弹簧组，该触点弹簧组具有一个中间的触点弹簧(52)和两个外侧的触点弹簧(51和53)。为了自动地切换触点弹簧组，设有两个能旋转的开关杠杆(1和2)，这两个开关杠杆交替地与触点弹簧组的触点弹簧(51、52、53)相接合。为了手动地切换触点弹簧组而提出，给触点弹簧(51、52、53)和第二开关杠杆(2)配设能手动旋转的、能使其从中性的中间位置进入第一和第二开关位置的调节杠杆(35)。通过所述调节杠杆(35)，能使中间的第二触点弹簧(52)在第一开关位置中与外侧的第三触点弹簧(53)持久地接触，同时能使其与外侧的第一触点弹簧(51)相分离。在第二开关位置中，能通过所述调节杠杆(35)这样调节第二开关杠杆(2)，使得外侧的第三触点弹簧(53)与中间的第二触点弹簧(52)分离，而外侧的第一触点弹簧(51)可靠地、持久地与中间的第二触点弹簧(52)接触。
摘要（英）：

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 manuallyrotatable 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).
