Abstract

A dual-purpose switch comprises a normal switch button, a time-delay switch button, and a time-delay control module. An AC (alternating current) power supply, a normal switch button and a bulb are connected in sequence; and the AC supply, the time-delay switch button, the time-delay control module and the bulb are connected in sequence. When the normal switch button is turned on, the time-delay switch button and the time-delay control module do not work, so that the dual-purpose switch has the same functions as the normal switch; when the bulb lighting is needed for the short time, the time-delay switch button is pressed, and then the AC power supply charges the time-delay control module for a short time, and provides a short-period electric power in about one minute to the bulb through the time-delay control module.

Description

dual purpose switch

Technical field

The utility model relates to an electric control device, in particular to a switch.

Background technique

In some places such as aisles and toilets in the home, users often need to temporarily enter and then leave. After the ordinary switch is turned on, it is necessary to operate the switch again to turn off the light. If you forget to turn off the light, it will cause power waste.

Contents of the invention

In order to overcome the above problems, the utility model provides a dual-purpose switch, the dual-purpose switch has two switch buttons, the normal switch button controls the same function as the ordinary switch button, after the delay switch button is pressed, the bulb lights up for one After about 10 minutes, it will be closed, and the user can operate the corresponding switch according to different needs.

The technical scheme adopted by the utility model to solve its technical problems is: the dual-purpose switch includes a normal switch button, a delay switch button, and a delay control module, and is characterized in that: the AC power supply, the common switch button, and the bulb are connected in sequence, and the AC power supply, The delay switch button, the delay control module and the light bulb are connected in sequence. When the ordinary switch button is turned on, the delay switch button and the delay control module do not work, and the dual-purpose switch has the same function as the ordinary switch; The module is charged for a short time, and the light bulb is provided with short-term power for about one minute through the delay control module.

The beneficial effect of the utility model is that the structure is simple, the cost is low, the production is easy, and the utility model has extensive use value.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is a functional block diagram of the utility model; Fig. 2 is an electrical structure diagram of the utility model.

In the figure, 1. AC power supply, 2. Common switch button, 3. Delay switch button, 4. Delay control module, 5. Light bulb.

Detailed ways

In Fig. 1, the dual-purpose switch includes a normal switch button 2, a delay switch button 3, and a delay control module 4. The switch button 3, the delay control module 4, and the light bulb 5 are connected in sequence. When the ordinary switch button 2 is turned on, the delay switch button 3 and the delay control module 4 do not work, and the dual-purpose switch has the same function as the ordinary switch; 1 pair of delay control module 4 is charged for a short time, and the bulb 5 is provided with short-term power for about one minute through the delay control module 4 .

In Fig. 2, when normal lighting is required, the switch K is closed, and 220V alternating current is directly applied to the light bulb. If it is only a short-term lighting, you can press the S button switch. At this time, the mains will quickly charge the capacitor C through the button switch, resistor R1, and D. After releasing the S button, the thyristor will be turned on due to the discharge of the capacitor through R2, and the bulb will be turned on. The delay is about 1 minute.

Claims (1)

1. a kind of dual-purpose switch comprises normal switch button (2), delay switch button (3), delay control module (4), is characterized in that: AC power supply (1), common switch button (2), bulb ( 5) Connecting in sequence, the AC power supply (1), the delay switch button (3), the delay control module (4), and the light bulb (5) are connected in sequence.
