How to use BT136 and BT139 Triac ?. 230volt ac load. Problem. Spkie

hello all,

i need help. developing home automation. have tried use triac bt136 , bt139.

while using triac got 100millisecond spikes when switch on nearest loads in home.
the cfl bulb on , off when switch on nearest loads in home.

(example: hardware , arduino live time switch on nearest loads uisng wall switch manually got small spike on cfl) cfl blink once.

i have connected triac cfl bulb. triac operated arduino using moc3041.
i tried many circuit possibilities cant

i tried snubber rc.
0.1uf , 2w 100 ohm resistor. no improvement.

please help.

and can use moc3041 optocoupler directly switch on loads ?.
i checked cfl bulb moc3041 once switched on , not off.

any 1 give me idea solve problem.

i have attached circuits withis post please find. got internet

have tried fitting mains rated contact suppressor across switch / device causing problem ?


have considered using ready made solid state relays, smaller 2, 3 or 4 amp modules can cheap building own, , lot safer.
however can still 'blink' component builds if have switching noise on power lines.
