Push switch

摘要

A push switch is adapted for use in combination with a variable resistance. The switch comprises an insulating driving body rotatably mounted on a slider which is adapted to be moved by a push rod or shaft, and at least two metal pieces carrying electrical contacts. These members are positioned within a casing in such a manner that the movement of the slider causes the driving body to be rotated by contact with a projection formed on one of the metal pieces. The rotation of the driving body causes electrical contacts to move to and from each other.
