Abstract
A kind of twice stroke turn on-switch, comprise rolling wheel type travel switch, pulling switch, pulling switch be drawstring through the perforate pole be fixed on rolling wheel type travel switch after, be fixed on the catch bar of rolling wheel type travel switch, the normally opened contact of rolling wheel type travel switch is connected with the switch contact of pulling switch.The catch bar of described rolling wheel type travel switch and the pivoted arm of pulling switch are mechanically connected.A kind of twice stroke turn on-switch of the utility model, can realize closing lamp when people leaves when door and extinguish, the function that lamp is lighted when people enters closedown.Realize light fixture by action of closing the door light and extinguish automation.
Description
Technical field
The utility model relates to a kind of switch, particularly a kind of twice stroke turn on-switch.
Background technology
Have in the enclosure space of door at one, to keep when there being people to enter door close and the light fixture of enclosure space light.When people leaves, door will be closed and the light fixture of enclosure space will extinguish.In prior art, or adopt simple switch, when people closes a switch, light fixture is lighted, and when people's shutdown switch, light fixture extinguishes, and can not realize automation, bring the work of many console switchs in a lot of occasion.Adopt digitalized electron element to realize automation function, but use and maintenance cost is high, and the various reliability of element reduce naturally, causes maintenance workload large.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of twice stroke turn on-switch, and this construction of switch is simple, does not rely on digitizing element, just can realize light fixture when enclosure space has a people and light, nobody time light fixture extinguishing function.
The technical scheme that the utility model is taked is:
A kind of twice stroke turn on-switch, comprise rolling wheel type travel switch, pulling switch, pulling switch be drawstring through the perforate pole be fixed on rolling wheel type travel switch after, be fixed on the catch bar of rolling wheel type travel switch, the normally opened contact of rolling wheel type travel switch is connected with the switch contact of pulling switch.
The catch bar of described rolling wheel type travel switch and the pivoted arm of pulling switch are mechanically connected.
A kind of twice stroke turn on-switch of the utility model, can realize closing lamp when people leaves when door and extinguish, the function that lamp is lighted when people enters closedown.Realize light fixture by action of closing the door light and extinguish automation.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is rolling wheel type travel switch of the present utility model, pulling switch series connection schematic diagram.
Embodiment
As shown in Figure 1 and Figure 2, a kind of twice stroke turn on-switch, comprise rolling wheel type travel switch 1, pulling switch 2, the bracing wire 4 of pulling switch 2 is through after the perforate pole 3 be fixed on rolling wheel type travel switch 1, be fixed on the catch bar 5 of rolling wheel type travel switch 1, the normally opened contact 6 of rolling wheel type travel switch 1 is connected with the switch contact 7 of pulling switch 2.The catch bar 5 of described rolling wheel type travel switch 1 is mechanically connected with the pivoted arm of pulling switch 2.
When the catch bar 5 of rolling wheel type travel switch 1 is owing to closing the door during action, the normally opened contact 6 of rolling wheel type travel switch 1 is closed, and pulling switch 2 action simultaneously, but bit line switch 2 has two kinds of the result of the action: i.e. switch connection and disconnection, and the normally open contact 6 of rolling wheel type travel switch 1 is connected with the switch contact 7 of pulling switch 2, so the utility model is in travel switch twice the result of the action, circuit is for once connected.Thus can realize closing lamp when people leaves when door and extinguish, when people to enter close time the lamp function lighted.
