Technical field

The utility model relates to a kind of low tension switch, the long and adjustable push-button switch of especially a kind of delay time.

Background technology

Low pressure time-delay push-button switch is widely used in generally including panel (or adding trim), pedestal or components and parts lid, button and control circuit in the building such as apartment building, and control circuit board is located on the pedestal, and button is located on the panel.

Behind the most of employing of the existing time-delay push-button switch diode rectification, control the controllable silicon conducting by discharging and recharging of Resistor-Capacitor Unit.Be characterized in that circuit is succinct, but delay time is shorter, generally can delays time about 2 minutes.Existing touch delay switch generally adopts capacitance decompression, power supply is provided for behind rectifying and voltage-stabilizing the monostable digital circuit, by human body touch, makes the upset of monostable digital circuit, the conducting of control controllable silicon.Be characterized in that circuit is succinct, easy to use, but delay time is also shorter.

More than two kinds of circuit because after the controllable silicon conducting, the voltage that offers circuits for triggering has only the silicon controlled conducting voltage, so delay time is shorter.In addition, no matter whether load works, load is all charged, makes troubles when giving the maintenance load.

Summary of the invention

The utility model aims to provide the long and adjustable time-delay push-button switch of a kind of delay time.

The technical solution adopted in the utility model is that the composition to delay control circuit improves on existing low pressure push-button switch structure for this reason.

The utility model comprises panel (or adding trim), pedestal (or components and parts lid, or control circuit lid, or the components and parts seat etc.), push-button switch and delay control circuit, pedestal is located at the back side of panel, push-button switch is located on the panel, as set up trim, trim can be located on the panel, the delay control circuit plate is located on the pedestal, said delay control circuit is provided with rectification circuit, voltage stabilizing circuit, delay circuit and control circuit, the input of rectification circuit connects push-button switch and load respectively, the output of the input termination rectification circuit of voltage stabilizing circuit, the output of the input termination voltage stabilizing circuit of delay circuit, the output of the input termination delay circuit of control circuit, the normally opened contact two ends of the electromagnetic relay of control circuit and push-button switch also connect, and establish the hole or the window that are used to regulate delay time on panel or pedestal.

Because the utility model adopts the principle of load step-down and electromagnetic relay control, therefore the voltage of control circuit is stable, delay time is long, but and regulated at will, difference according to circuit design, delay time can from tens seconds to dozens of minutes, even more than several hours, can be designed to usually in 1 to 25 minute.In addition, circuit is before loaded work piece, and load is not charged, and is convenient and safe when therefore keeping in repair load.
