ABSTRACT:
A pulse switch capable of producing a large number of pulses for its reduced size. The pulse switch has a rotatable shaft, a gear having peripheral teeth and provided with a hub portion, the gear being adapted to rotate as a unit with the shaft, an operation member provided at its end with an integral cam portion for engagement with the valleys of teeth of the gear and disposed to loosely fit the hub portion of the gear, and a switch having a center resetting mechanism. The center resetting mechanism is adapted to take a neutral position when the operation member is in the initial position, and to bring a slide contact into engagement solely with respective stationary contacts as the shaft is rotated selectively either in the clockwise direction or counter-clockwise direction.
