PURPOSE: A rotation angle limiting double stopper device of a hollow type volume switch improves the braking ability of a rotor as first and second stopper protrusions protrude. CONSTITUTION: A rotor (40) with a terminal (30) grounded to a rotary substrate (20) combined with a base (10) and a rotary plate (50) are successively combined with the base to be rotated. After a pair of first stoppers (14a,14b) and a pair of first stopper protrusions controlling the rotation angle of the rotor are formed on the lower surfaces of the base and the rotary plate, respectively, a cover (80) is combined with the front of the base. A pair of second stoppers is bent to the lower side of the cover. A pair of second stopper protrusions separately protrudes from the upper part of the rotary plate. The second stoppers are formed by punching a part between the upper part of a fixing part (82) and a second main body part (81). |
