Hi, I’ve been using a reed-relay in a circuit, wired as a vibrator. I chose the reed-type relay for the small size & cheaper price. I’ve been looking for a "solid-state" replacement for the relay with the same small size & price that will put out a pulse (on/off) signal of 1 amp or less with a 12 volt battery. The pulse signal is being used to constantly turn on & off a transformer. This isn’t that critical but maybe about .005 sec between pulses.
Ideally I’m looking for something the size & looks of a resistor, with 2 leads, an in & out; a single unit that will work constantly like an on/off switch to whatever it is hooked to.
I’ve been all over in my searches, there’s so much out there & I’m not really sure what name or key words to search for?
555 Oscillator? - looks more complicated than what I need, lots of parts to order & assemble to make it work.
Pulse width modulator?
IGBT?
Mosfets?
I’ve pretty limited in electronics but am learning. Thanks for your time & replies are appreciated.
