Abstract: An improved rotary line switch provided with an upper cover, a lower cover with trapezoid blocks and mushroom blocks on the internal walls thereof, a contact strip held by the mushroom block at one end of the lower cover, an inverted U shaped catch-contact strip having a catch end and a contact end held by the mushroom block at the other end of the lower cover, a control consisting of a knob and a lower ratchet wheel and an upper ratchet wheel each having four teeth, and a screw having a journal for the control to fit on and used to fasten the upper and lower cover together. The switch is constructed in such way that the S shaped end of a contact strip engages with a tooth of the lower ratchet wheel while the catch end of the catch-contact strip engages with a tooth of the upper ratchet wheel and serves as a catch of the same, and that when the knob is turned 90 degrees the lower ratchet wheel will push the S shaped end of the contact strip to contact with the contact end of the catch-contact strip once.
