hi,
i found tihs circuit, but i dont think about resistors and capasitors values. how can i make this circuit. input voltage 220V- 240V
 

i draw this shema. but its not working. comment please
thanks
 

i think the gate voltage applied exceeds that of bt136 maximum.

(R5, D1 and R4)

other than that a suggestion is show in diagram N.C contact(S2) as closed normally.
 

first tanks for important comment. i see. you say that R4-R5 values must be up? and normally s2 switch closed on my circuit.
 
have you connected S1 as push-to-on switch ?
and S2 as push-to-off switch?
 
yes im sure about s1 and s2 switch... i think i have a problem about r4-r5
 

i assume that you have connected MT1 MT2 terminals properly.

now for a test change R3 330K to 330ohms .
there must be a load connected for proper operation.
