While all starters are physically interchangeable, the wattage rating of the starter should be matched to the wattage rating of the fluorescent tubes for reliable operation and long life. The glow tube incorporates a switch which is normally open. When power is applied, a glow discharge takes place which heats a bimetal contact. A second or so later, the contacts close and provide current to the fluorescent filaments. Since the glow is extinguished, there is no longer any heating of the bimetal and the contacts open. The inductive kick generated at the instant of opening triggers the main discharge in the fluorescent tube. If the contacts open at a bad time, there isn't enough inductive kick and the process repeats. "The Daring Dufas" wrote in message ... Does anyone know where I can find or can you draw a wiring diagram for one of these Single push button starters for a 22w circline fluorescent bulb.

I took this lamp apart a LOOOONG time ago and finally found the right switch and know can't remember how to wire it up. The bulb socket has 2 blk wires and 2 white wires, the switch has 4 contacts.

Fluorescent starter-switch question
The combination on-off and starter switches have two sets of contacts. One set is just a regular on-off switch. The second set of contacts provides the momentary closing to heat the filaments of the tube. When the contacts open when the switch is released, the inductive kick from the ballast/transformer is usually high enough to strike an arc across the tube. The longer the tube, the higher the overall volatage across from one end to the other. The glow starter must not ionize at the voltage that is across the tube, hence the need for various starters to work with various fluorescent tube wattages/lengths.

Take it apart and draw a schematic yourself you can't why not? |
