it happenssThat will be the last resort.
Anyways theres also a weird problem with this ckt.
I switch a relay and theres a incandescent lamp in the contacts.When I switch this on/off it does it well.But when I try an Inductive load,the MCU jumps to a routine simulating a key press,which is an active high switch,when used.
Is this also relating to the current issue?...or something else...???
Anyways Thanks so much for taking interest in my woes...
you need to put an MOV across the contact . say , if you are using it for 230V, then MOV could be 250V . otherwise and R-C series network acoss the contact would act like spark quench.with R at 1K 1 watt and C at 0.047/600V
