Summary:The utility model discloses a contact type pull switch. A gear (5) and a rotary gear (3) are driven to slide in a guide way by a pull wire body (6); the four teeth of the rotary gear (3) alternately enter a depth guiding groove in the guide way (4) to control the circuits to be switched on or switched off instead of the traditional pull switches. The quantity of metallic material is reduced, and except for conductors, springs and screws, other components are made of plastic; the number of broken times of the pull wire is reduced; the installation of the pull wire is carried out out of the contact type pull switch, which is convenient and safe.
