Abstract
The utility model discloses a plastic time delay switch which is made of plastics except the electrode and the spring. The pressing of the push button can make the circuit communicated, and after one or two minutes, the electricity is cut automatically. The using of the utility model in the corridor can omit the trouble of switching off the light by the way when going upstairs or downstairs. One time delay switch can replace two two-way switches. The cost is less than one Yuan. The utility model is the upgrading and generation changing product. Through one year using and working, the plastic time delay switch is completely reliable.
Description
This switch belongs to civil electric appliance.
The corridor switch that uses in the building is bidirectional switch mostly now, needs lamp holder of two switch control, Zong the trouble that unavoidably Turn Off Lights When Leaving, otherwise be exactly bright whole night altar lamp, or the ornaments that do not work always.Therefore the modern life be starved of a kind of inexpensive, the automatic time delay stopcock that the life-span is long.The complicated cost height of existing electronic time-delay switch and mechanical timer is not suitable for promoting and makees the corridor switch.
These plastics delay switch has solved above-mentioned all disadvantages, and it is simple in structure, and cost less than 0.5 yuan is very easy to use.One touches the button promptly switches on, through one period that you set up (1-2 minute) outage automatically.Saving the trouble that Turn Off Lights When Leaving, is energy-conserving product, and this switch sample 1 year on probation proves reliable fully.
Delay switch is by panel, button, moving electrode, and stationary electrode and air chamber part are formed.Its moving electrode is a slice dish copper sheet, and the air chamber part is made up of air valve, valve seat and bellows etc.Wherein bellows core has a spring to prop up air valve and valve seat so that switch resets.Bellows and valve seat, base tight fit, valve seat can slide in the supporting slice mesopore.Base is connected with shell.There is the screw and a soft packing ring of an adjusting intake velocity at its base center.
