FOOT CONTROL FOR SWITCHING OF AN ELECTRIC DRIVE

摘要

A foot control particularly for a dictating apparatus. The electric drive of the dictating apparatus is to be switched between an inoperative mode, a forward mode and a reverse mode and the switching between these modes is to be sequential. A housing includes an upwardly open lower shell section and a superimposed downwardly open shell section having two spaced marginal portions. The sections are connected with bayonet-type closures permitting the upper section to move upwardly and downwardly with reference to the lower section. A leaf spring is located in the housing and has a first end portion fixed to the lower shell section and urges the upward shell section upwardly with its remote second end portion. A spherical element is interposed between the second end portion and the upper shell sections so that the latter rocks about the spherical element with reference to the lower shell section when downward pressure is applied on one of two spaced marginal portions of the upper shell section. Pressure on one of these marginal portions causes the upper shell section to be rocked downwardly to a first position in which the drive is switched from inoperative to forward mode, and pressure on the other marginal portion causes the upper shell section to be rocked downwardly to a second position in which the drive is switched sequentially past the forward mode to a reverse mode.
