Abstract (en)

[origin: EP0301469A2] The invention relates to a pulse generator having an operating element which can be moved by a gearwheel over a latching projection, and which, when displaced, can operate contact springs fitted on the sides. A relatively large spacing is required on the sides between the contact springs and the operating element, which is bent from a metal strip of sprung material, in order to prevent a short-circuit between the two mutually opposite contact springs on the sides. This necessitates a dead angle of rotation through which the gearwheel must be rotated before operation of a contact spring is possible. In addition, a separate latching spring is provided and is used to define the rest positions of the gearwheel. <??>The operating element (10) is produced from dielectric material and is pressed against the gearwheel (4) by a compression spring (12). The compression spring is also used as the latching spring. <??>The pulse generator is particularly suitable for the emission of current or voltage pulses for adjusting the frequency of digitally adjustable devices. <IMAGE>
