Link address line of codes.
Preferably, in above-mentioned jerk latch switch, the quantity of the double control switch is 5~8.
Preferably, in above-mentioned jerk latch switch, including housing and the guide rod in the housing, the dual control is opened
The actuating mechanism of pass and the guide rod slidable connection.
Preferably, in above-mentioned jerk latch switch, the terminal board for being easy to wiring, the terminal are provided with the housing
Plate has multiple terminals.
Preferably, in above-mentioned jerk latch switch, including drawstring, the drawstring is opened by executing agency with the dual control
The actuating mechanism of pass is connected, and the executing agency has mechanical locking function.
A kind of ribbon conveyer for colliery, including jerk latch switch, the jerk latch switch are above-mentioned any
Jerk latch switch disclosed in one.
It can be seen from above-mentioned technical proposal, in the jerk latch switch that the present invention is provided, there is provided multiple double control switches, and
And, the fully synchronized action of double control switch, because the normally opened contact of double control switch is connected with geocoding line, it is possible to according to urgency
Numbering and binary system the principle selection of lock-switch of closing down needs the normally opened contact of link address line of codes, records jerk with this and closes
The address of lock-switch, thus can realize being quickly found out the function of abort situation using the jerk latch switch, and due to the urgency
Lock-switch of closing down comes coded address using mechanical switch, it is possible to the adverse circumstances of underground coal mine are adapted to, with conventionally employed collection
Jerk latch switch into circuit board is compared, and the jerk latch switch fault rate that the present invention is provided is few, can efficiently reduce fortune
The maintenance cost of defeated line.

Specific embodiment
In order to make it easy to understand, the invention will be further described below in conjunction with the accompanying drawings.
It is a kind of connection principle schematic diagram of jerk latch switch provided in an embodiment of the present invention referring to Fig. 1 and Fig. 2, Fig. 1,
Fig. 2 is a kind of schematic diagram of jerk latch switch provided in an embodiment of the present invention.
A kind of jerk latch switch provided in an embodiment of the present invention includes multiple double control switches 31, and double control switch 31 is all same
Step is acted, and the tie point of one end of double control switch 31 and the normally-closed contact of the other end are all connected with control signal wire, double control switch 31
Normally opened contact be used for link address line of codes.
As shown in figure 1, input 8 and output end 9 are used for connection control signal line, address end 10 encodes for link address
Line, in the present embodiment, input 8 and output end 9 include six circuits, for connection control signal line, one of line respectively
