Abstract
The utility model relates to a point type multi-control magnetic pull switch which can conveniently control the same one operating circuit in different positions. The switch adopts the structure that a ratchet wheel, an normally open switch and an electric magnet are arranged in an insulating casing; a driving pawl of the ratchet wheel and a check pawl of the ratchet wheel are electrically connected in sequence through the ratchet wheel; the electric magnet and a return spring are respectively arranged on two sides at the tail end of a swing link of the ratchet wheel; and the electric magnet is connected with the built-in normally open switch in series. When the switch is connected with a power source, the operating circuit and a plurality of external normally open switches, by only pressing any one of the normally open switches, the operating circuit can be controlled, and the switch can be widely applied to the controlling of various circuits in multiple positions.
Description
Technical field
The utility model belongs to a kind of circuit control device, especially can control the point type ten thousand control magnetic drag switches of same operating circuit from several different locations.
Background technology
At present, known circuit control device is though can carry out break-make control to circuit, but, a lot of workplaces require to control same operating circuit from several different locations, and require cost low, easy for installation, and general circuit control device is difficult to meet the demands.
Summary of the invention
Can not satisfy the point control of many ground, low cost and deficiency easy for installation in order to overcome the available circuit control device, the utility model provides a kind of point type ten thousand control magnetic drag switches, these point type ten thousand control magnetic drag switches both can be controlled same operating circuit from several different locations easily, and cost is low, easy for installation.
The technical scheme that its technical problem that solves the utility model adopts is: in insulation crust, a ratchet, a back-moving spring, an electromagnet and a built-in normal open switch are set, and make electromagnet and back-moving spring be separately positioned on the both sides of ratchet swing rod end, ratchet initiatively pawl-and-gearing check pawl is electrically connected by the ratchet order, and electromagnet is connected with built-in normal open switch.When these point type ten thousand control magnetic drag switches are connected with power supply and operating circuit, when built-in normal open switch follows several external normal open switch in parallel, as long as built-in normal open switch or any one external normal open switch closure in parallel with it once, make the electromagnet moment energising in the point type ten thousand control magnetic drag switches, electromagnet produces magnetic because of energising, attract fork that ratchet is rotated, the active ratchet of ratchet and the contact position of check pawl on ratchet just change, thereby the break-make situation that reaches the circuit of forming between active ratchet and the check pawl changes, so that the break-make of operating circuit change, thereby reach the purpose of Control work circuit.
The beneficial effects of the utility model are: when operating circuit is carried out control, can realize the point control of many ground, and easy to operate; External normal open switch adopts parallel way to connect, and is easy for installation; The component structure that adopts is simple, and cost is low.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is circuit theory diagrams of the present utility model.
Fig. 2 is the control principle figures of point type ten thousand control magnetic drag switches to circuit.
1. built-in normal open switch among the figure, 2. electromagnet, 3. ratchet active ratchet, 4. ratchet swing rod, 5. back-moving spring, 6. operating circuit contact, 7. electric light, 8. power contact, 9. power supply, 10. ratchet check pawl, 11. ratchet, 12. metal wires, 13. external normal open switch contacts, 14. external normal open switch.
Embodiment
In Fig. 1, ratchet 11 is made of plastics, and metal wire 12 is installed, ratchet active ratchet 3 and ratchet check pawl 10 are made of metal, ratchet swing rod 4 is made by ferrous metal, end at ratchet swing rod 4, initiatively electromagnet 2 is set the same side of ratchet 3 with ratchet, opposite side is provided with back-moving spring 5 traction ratchet swing rods 4, electromagnet 2 is connected with built-in normal open switch 1, operating circuit contact 6 can connect operating circuit, and power contact 8 can be connected with power supply, and external normal open switch contact 13 can external normal open switch in parallel.
In embodiment illustrated in fig. 2, electric light 7 is linked to be path by ratchet active ratchet 3, metal wire 12, ratchet check pawl 10 and power supply 9, and electric light 7 is normally luminous.
In the above-described embodiments, when pressing built-in normal open switch 1 or external normal open switch 14 to make it closure, electromagnet 2 energising band magnetic, attract ratchet swing rod 4, ratchet 11 turns over a tooth pitch, and ratchet is initiatively become by path between ratchet 3 and the ratchet check pawl 10 and opens circuit, and electric light 7 breaths go out; After built-in normal open switch 1 or external normal open switch 14 lost the external force disconnection, electromagnet 2 lost magnetism, and ratchet swing rod 4 resets under the traction of back-moving spring 5.When pressing built-in normal open switch 1 or external normal open switch 14 to make it closure once more, electric light 7 place circuit become connection by disconnection again.Be every when pressing built-in normal open switch 1 or external normal open switch 14 to make it closure, the break-make situation of electric light 7 place circuit just changes once, thereby realizes electric light 7 place circuit are controlled.
In the above-described embodiments, as long as at built-in normal open switch 1 two ends several external normal open switch in parallel, the circuit of electric light 7 is during for operating circuit arbitrarily, just can be implemented in several different places and same operating circuit is carried out controlled.
Claims (1)
1. a point type ten thousand is controlled the magnetic drag switches, in insulation crust, ratchet initiatively pawl-and-gearing check pawl is electrically connected by the ratchet order, it is characterized in that: at the terminal opposite side with back-moving spring of ratchet swing rod an electromagnet is set, and this electromagnet is connected with a built-in normal open switch.
