Abstract
The utility model discloses a discrimination sound switch, belonging the field of to a control device of an appliance switch. The utility model is of a switch recognizing the on and the off state of the switch through sound. A ratchet wheel comprises a concave cavity, a hollow room, and L-shaped materials. The on and the off state of the switch are differentiated obviously by the utility model through different sound and different positions, wherein, the different sound and the different positions is generated by the contact and collision of different materials or different structures with a metal sheet. The utility model has the advantages of simple structure, energy saving, safety and convenience, and convenience provided for the blind and the dumb.
Description
The utility model provides a kind of Discrimination sound switch, belongs to the electrical apparatus control equipment field.
The sound people ear that existing switch sends when switching on and off can not distinguish it is logical or disconnected, can only see electrical appliance is whether luminous or listen an electrical appliance whether sounding is judged, circuit has a power failure or electrical appliance has fault to install when overhauling, judge that switch on and off is very inconvenient, and accidents happened easily, after the power failure people withdrew from a room, electricity came the bright electricity wasting of lamp.
The utility model provides a kind of switch that can recognize break-make sound, just often still is easy to use at circuit and electrical appliance.When circuit power failure or installation and maintenance or people withdrew from a room, it was logical or disconnected just can recognizing switch with sound, to avoid the generation of accident, i.e. and safe ready, but electrical energy saving again.
The utility model Discrimination sound switch is the alternative sounds that sends during according to the material of different materials or the structure contact-impact other break-make of breaking, when former switch disconnects, sheet metal and bakelite contact-impact are sounded, settle an insulating material that can send sound when being different from out at bakelite one side's contact point place, with insulating material softness or hard, or constitute special construction in the bakelite contact position, as hollow or change the contact distance of metallic laminas bakelite, to produce especial sound.
Fig. 1 is the insulating material three-view diagram, makes with sponge or other soft material, and its structure is cylinder three forked types that coincide with ratchet, and soft insulating material is placed on the ratchet, sends weak sound when making shell fragment and its collision and is in off-state to show switch.
Fig. 1. be an embodiment of the present utility model.
Fig. 2-1 is the ratchet front view.
A is the special construction of a cavity.The A cavity can be placed soft insulating material, and in the time of also can placing the conducting copper sheet ratchet is rotated, shell fragment and its collision produce extraordinary sound.
B is-hollow, and shell fragment sent different sound with its collision when ratchet was rotated.
C is-L type structure, to weaken the collision of shell fragment and ratchet.
Fig. 2-2 is the ratchet left view.
Fig. 2-3 is the ratchet cutaway view.A, B are for cuing open the position.
Fig. 2 is another embodiment of the utility model.
The utility model, simple in structure, using electricity wisely, safe ready uses extensively, also can be the blind person and provides convenience.
Claims (1)
1, a kind of novel switch of arguing is characterized in that in the switch and the identical cylinder three forked type soft materials of ratchet, and the structure of ratchet has cavity (A), hollow (B), L section bar material (C).
