Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of electromagnetic relay, comprise lever 1, fulcrum 2, extension spring 3, first solenoid 4, first touch-pressure switch 5, second solenoid 6, second touch-pressure switch 7, power supply tie-in line 11, first power outlet 8, second source outlet 10, bidirectional switch 9, described bidirectional switch 9 comprises plug-in strip 91, upper contact 93, lower contact 92, described first touch-pressure switch 5, second touch-pressure switch 7 includes feeler lever, the contact, described fulcrum 2 is located at lever 1 lower end, the plug-in strip 91 of described bidirectional switch is connected the back and is fixed on the left end of lever 1 with power supply tie-in line 11, the lower contact 92 of described bidirectional switch is connected with first power outlet 8, the upper contact 93 of described bidirectional switch is connected with second source outlet 10, described first solenoid 4, the series connection back, contact of first touch-pressure switch 5 is connected with external power source AC, described second solenoid 6, the series connection back, contact of second touch-pressure switch 7 is connected with external power source AC, the feeler lever of described first touch-pressure switch 5 is connected on the lever 1 between lever 1 right-hand member and the fulcrum 2, the feeler lever of described second touch-pressure switch 7 is connected on lever 1 right-hand member, and described extension spring 3 is connected on the lever 1 between lever 1 left end and the fulcrum 2.Distance between the feeler lever of the feeler lever of described first touch-pressure switch 5 and second touch-pressure switch 7 is 1/4 of lever 1 length overall.Described fulcrum 2 is 1/4 of lever 1 length overall with the distance of lever 1 left end.
Relay is in conducting when going into off-state, drives bidirectional switch 9 control power supply tie-in lines 11 by lever 1 and connects with first power outlet 8 and second source outlet 10 respectively, to reach the effect of relay.
When control relay circuit disconnected, this moment, bidirectional switch was strained by extension spring 3 one, and the power supply tie-in line 11 and first power outlet 8 are connected.
When control relay circuit was worked, first touch-pressure switch 5 was a conducting state, first solenoid, 4 work this moment, and the lever right-hand member is pulled down, and lever 1 drives bidirectional switch 9 at this moment, and the power supply tie-in line 11 and first power outlet 8 disconnect; While lever right-hand member touches second touch-pressure switch, 7, the second solenoids, 6 circuit and is switched on, and second solenoid 6 is started working, and continues pull lever 1 to pressing down.When lever 1 contact second solenoid 6, this moment, lever 1 pressed first touch-pressure switch 5, and first solenoid 4 is quit work.This moment, the work pulling force that produces of second solenoid 6 made the bidirectional switch connection lambda line power line and the second source outlet 10 of lever left end.Relay is finished the operation of commutation circuit.
When control relay circuit cut out, lever set back under the effect of extension spring one, power supply tie-in line 11 and 8 conductings of first power outlet.Relay returns back to initial condition.
