Description

The fine motion regulating switch

The utility model relates to power control switch, is a kind of fine motion regulating switch that can regulate lighting brightness, electric fan revolution.

At present, lighting lamp control switch mostly adopts pulling switch and sticks up the formula switch, these control switchs can not be regulated the brightness of illuminating lamp, and indoor illumination needs the brightness height at ordinary times, need brightness low when seeing TV, need brightness minimum in bed, not only waste electric energy but also use inconvenience with this class switch.

The purpose of this utility model provides a kind of fine motion regulating switch, can not regulate the brightness of illuminating lamp to solve existing control switch, not only wastes electric energy but also use inconvenient problem.

The purpose of this utility model is achieved in that this switch is to be made of panel, switch and box body, panel is provided with 1-4 shelves interlocking switch, an indicator light, two screw holes, be provided with a platform at back side of panel, prop up on the platform by the intrinsic circuit board of screw, be provided with through wires hole at the bottom of the box body, in have screw to prop up platform, panel and box body are fixed together by screw.

Circuit is by master switch and the resistance that is connected in parallel, the switch indicating circuit that two-way LED constitutes; By interlocking switch, potentiometer, the phase-shift trigger circuit that resistance and electric capacity constitute; Form by control circuit and load that master control bidirectional triode thyristor BCR and bidirectional trigger diode constitute.

At bidirectional triode thyristor BCR and power supply one end, be in series with coil L ₁, the other end is parallel with electric capacity and constitutes filter circuit.

This utility model compared with prior art has the following advantages: 1) be provided with the interlocking switch of 1-4 shelves different capacity, the user can select lighting brightness as required arbitrarily; 2) adopt trimmer potentiometer easy to adjust; 3) with this control switch control electric fan, easy and simple to handle, every grade of revolution of electric fan is also fine-tuning, and long service life, saves electric energy.

Be described further below in conjunction with accompanying drawing:

Fig. 1 fine motion regulating switch structural representation;

Fig. 2 fine motion regulating switch right view;

Fig. 3 electrical schematic diagram.

Among Fig. 1-2: panel (1), box body (2) adopt plastics or ceramic material to make, and panel (1) is provided with master switch (3), and it adopts and sticks up the formula K switch ₁, 1-4 shelves interlocking switch (4) is arranged, it adopts fine motion block push button VK ₁, VK ₂, VK ₃, VK ₄Indicator light (6) adopts two-way LED, two screw holes are arranged, be provided with a platform at panel (1) back side, prop up on the platform by the intrinsic circuit board of screw (5), box body (2) end, be provided with through wires hole, is provided with screw in the box body and props up platform, by screw (7) panel (1) and box body (2) is fixed together.

Among Fig. 3: power supply is 220 volts of alternating currents, as mains switch K ₁After the connection, by 1-4 shelves fine motion block push button VK ₁, VK ₂, VK ₃, VK ₄Control respectively, corresponding each fine motion block push button is connected in series with potentiometer W respectively ₁, W ₂, W ₃, W ₄And resistance R ₁, R ₂, R ₃, R ₄, with capacitor C ₁Form phase-shift trigger circuit (9); By master control bidirectional triode thyristor BCR be connected on the bidirectional trigger diode ST that SCR control extremely goes up and constitute control circuit (10), at master switch K ₁Two ends are connected in parallel to resistance R ₅With two-way LED, constitute switch indicating circuit (8), at bidirectional triode thyristor BCR and power supply one end, be connected in series with coil L ₁The other end is parallel with capacitor C ₂Constitute filter circuit (11); Load (12) is illuminating lamp or electric fan.As mains switch K ₁Connect with any fine motion block push button, at certain half cycle of alternating voltage, 220 volts of alternating currents through potentiometer and resistance to capacitor C ₁Charging, capacitor C ₁Both end voltage rises, and works as C ₁When both end voltage is elevated to greater than the blocking-up value of bidirectional trigger diode ST, just conducting in succession of ST and bidirectional triode thyristor BCR, regulator potentiometer just can change the trigger angle of controllable silicon BCR, thereby change the size of load current, promptly change the load both end voltage, play random light modulation effect, in like manner can arbitrarily control the electric fan revolution.
