Re: are silicon bilateral switches be used as diacs?
The heating element is a Kapton wire wound kiln heater. I cut a 220V one into two and want to run it on 110V. The element temp is a function of the length of the element( actually the resistance) and the voltage. Since the length is fixed I need to be able to control the voltage. When I melt aluminu...

Re: triac problems..
Hey Dac: You are trying to use Neon lights with a triac type dimmer pack? Two things to consider: Use a relay type controller like the American DJ SC8FC system which is a hard wired remote contoller with 8 relay channels and a 25 foot control cable.(about $135). Or as a homebrew fix, control the neo...

are silicon bilateral switches be used as diacs?
I had a circuit that worked with a 5 amp triac (using a diac for a trigger in the gate)and when I used a 40 amp triac, it doesn't dim smoothly. It snaps on at about 3/4 of the turn of the pot. I have some silicon bilateral switches and wonder if they are an equiv. substitute for a diac? Anybody have...

Re: triac problems..
Switching the primary of a transformer on and off is hard on equipment. The inrush current is very high the power is applied and the kickback is bad when the primary is de-energized. I would switch to 120V lights and forget the transformer lights. I sell these for a living and have had many bad expe...
