Abstract
The utility model relates to a switch with an indicating lamp. When the indicating lamp is bright, the switch with an indicating light is free from the influence of the change of a power supply voltage, and the usage is safe. When an illuminating lamp is switched off and the indicating lamp (a neon tube) is bright, the indicating lamp does not form a loop with a power supply. The neon tube has the characteristic of emitting light by induction. One end of the neon tube is connected with a live wire through a resistor, and the other end is connected with a section of conducting wire which is arranged in a wall and insulated from the wall. Through the induction of the wall, the indicating lamp can emit light. The switch position can be quickly found at night.
Description
The utility model is the utility model about the switch of tape light.The switch of existing tape light, after illuminating lamp was switched off, indicator light and power supply constituted the loop, are in luminance.Usually the indicator light fluorescent lifetime is much longer, luminous for a long time according to bright lamp, can influence the indicator light life-span.And when supply voltage raises, might burn out element, even cause danger.
The purpose of this utility model provides a kind of switch of improved tape light, does not constitute the loop with power supply when indicator light is bright.Can find the position of the switch rapidly at night.
The utility model is made up of a single-pole single-throw(SPST or single-pole double-throw switch (SPDT), a neon tube and a resistance, and neon tube is made indicator light.The utility model has utilized neon tube to be subjected to inducing luminous characteristic.Fig. 1 is the circuit diagram of the utility model when using separately.Control with single-pole double-throw switch (SPDT).Neon tube one terminating resistor, one section lead (lead is placed within the walls, is tied with adhesive plaster on the end of a thread) that insulate with wall of another termination.When illuminating lamp was bright, neon tube and live wire disconnect, and be not luminous; Turn off illuminating lamp, neon tube is by the resistance line of starting to exchange fire, and by the induction of wall, neon tube is luminous.
Fig. 2 is the circuit diagram that the utility model is used for desk lamp.With single-pole single-throw switch (SPST) control, to allow switch connecting to neutral line when connecing power supply.Neon tube one terminating resistor, the metal tube of another termination desk lamp.Close a switch, neon tube is by resistance connecting to neutral line, and is not luminous; Open switch, neon tube is by resistance and the bulb line of starting to exchange fire, and by the induction of metal tube, neon tube is luminous.
The influence that the utility model is not raise by supply voltage, safe in utilization.Owing to there is not electric current to pass through, the indicator light life-span prolongs.
Claims (1)
- The switch of the tape light of forming by a single-pole single-throw(SPST or single-pole double-throw switch (SPDT), neon tube and resistance, an end is by the resistance line of starting to exchange fire when it is characterized in that indicator light is bright, and one section of another termination is placed within the walls and with the lead of wall insulation or connect the metal tube of desk lamp.
