Abstract

The utility model relates to an electric switch, it has solved the defect that the non-delay function that the background art exists and produce electric arc. The technical characteristic is that a switch contact 5 and a control contact 7 arranged below the shell of the original mechanical switch are connected with an electronic delay circuit board 4, and an alternating current power supply input line connector 6 and an output line connector 8 are arranged on the electronic delay circuit board 4. The utility model has the effects of time delay and safety, and can be widely used for controlling the on-off of circuits in places such as houses, hotels and the like.

Description

A kind of appliance switch

The utility model relates to a kind of appliance switch, particularly a kind of appliance switch with delay function and the generation of no electric arc.

During the background skill is asked, dwelling house, the used appliance switch of hotels and other places, modal is common wall dibit appliance switch.The basic structure of this switch is: the shell of switch is provided with button and panel, is provided with the binding post of power supply input and output line below the shell.The switch of obvious this structure can only make circuit be in conducting and disconnect two states when working, time-delay closing after needed switch disconnects when can not realize some, the another kind of defective of this kind switch is to disconnect or turning circuit by Mechanical Contact, thereby generation electric arc, under some inflammable condition, may bring out fire, be unfavorable for safety utilization of electric power.

The purpose of this utility model is to propose a kind of appliance switch with electronic delay plate structure, to solve existing the above defective of background technology.

The technical solution of the utility model is to realize like this, a kind of appliance switch, panel and switch key are set above the switch housing, mechanical switch contact and control contact are set below the shell, close contact and be connected the electronic delay wiring board, AC power incoming line joint and output line joint are set on the electronic delay wiring board with the control contact.

Advantage and good effect that the utility model and background technology comparison are had are: owing to adopt the appliance switch that has the electronic delay wiring board, on the one hand needing under the situation of time-delay closing (closing again after needing the people to leave as the passageway lighting lamp), can first off switch button, at this moment because the still conducting of application circuit of delay circuit plate.Automatically close after lasting till the delay time of setting.On the other hand, the conducting of circuit or disconnection adopt electronic component to realize, have avoided the electric arc that mechanical collision produced, and are applicable to the safety utilization of electric power of Combustible Place.

The utility model description of drawings is as follows:

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model electronic delay wiring board electrical schematic.

Below with embodiment the utility model is further elaborated:

Embodiment: with reference to figure 1, panel 1 and switch key 2 are set above the electric switch shell 3, mechanical switch contact 5 and control contact 7 are set below the shell 3, switch contact 5 is connected electronic delay wiring board 4 with control contact 7, the electrical schematic of delay circuit plate 4 as shown in Figure 2, AC power incoming line joint 6 and output line joint 8 are set on the electronic delay wiring board 4, and then whole proposal is implemented to finish.

Claims

A kind of appliance switch, panel 1 and switch key 2 are set above the switch housing 3, mechanical switch contact 5 and control contact 7 are set below the shell 3, it is characterized in that switch contact 5 is connected electronic delay wiring board 4 with control contact 7, is provided with AC power incoming line joint 6 and output line joint 8 on the electronic delay wiring board 4.
