Description
Technical field:
The utility model relates to a kind of rotary switch, is a kind of rotary switch with the parchment coffee heating furnace specifically.
Background technology:
At present, the commercially available used switch of coffee heating furnace mostly is seesaw (ship shape) or trigger piece (rocking arm) switch, by pressing button or pulling the trigger piece console switch, make switch be in the switching state, these switches have only two grades, and shape is single, has influenced outward appearance U.S. of coffee heating furnace and has made coffee heating furnace outward appearance be difficult to accomplish diversity.
The utility model content:
Task of the present utility model is to provide a kind of rotary switch, and it has third gear, again can with the harmony in appearance of coffee heating furnace, increase aesthetic feeling.
For finishing above-mentioned task, the solution that the utility model is taked is: a kind of rotary switch, comprise pedestal, lid, fixed contact, moving contact and rotating shaft, the swiveling wheel lower end is fixed in the hole of pedestal, top links by plate and rotating shaft, copper sheathing is housed in the lateral aperture, sleeve spring in the copper sheathing, pedestal is embedded with Qian shape fulcrum, place the V-arrangement contact bridge that moving contact is set under the two ends in the middle of the Qian shape fulcrum, copper sheathing contacts with the V-arrangement contact bridge, Qian shape fulcrum is connected with middle-end, middle-end is stretched out base bottom, and two limit ends are riveted with two fixed contacts respectively, and the limit end stretches out the pedestal side.
The utility model adopts Qian shape fulcrum and V contact bridge structure, makes it to become third gear switch, promptly makes switch be in the ON-OFF-ON state respectively by rotating shaft.Rotating shaft rotates swiveling wheel by plate, and the action of V-arrangement contact bridge makes the switch on-off.The active force of spring acts on the V-arrangement contact bridge by copper sheathing, and the V-arrangement contact bridge is contacted well with Qian shape fulcrum, and the moving contact below the V-arrangement contact bridge two ends contacts well with fixed contact.Owing in the rotating shaft of this switch various knob can be installed, make it to coordinate mutually in appearance with the coffee heating furnace, can accomplish harmony, increase aesthetic feeling, improve people's desire to buy; And this switch can directly be installed and used under the situation that does not change former other accessory size of coffee heating furnace, replaces existing seesaw (ship shape) or trigger piece (rocking arm) switch.This rotary switch also can be used for other household electrical appliance.
