For a glow plug timer, you probably want an 'on-delay' type then feed power through a normally closed contact on the timer (from the same controlled power as the coil).
Power turns ON, the timer starts timing and also gets fed through the NC contact to the load.
When the timer expires, the contact opens, shutting off the load after the defined time.
A latch relay may be what you are thinking of. They change with a 20ns pulse. Like a ballpoint pen. The coil "clicks" on and off with a pulse.Good idea, however it would be better if the relay did not have a coil that would be constantly engaged. Is there a terminology for a relay that will be on for a set period of time when the power turns on and then shuts off until the power is turned off and back on?
20 "nanosecond" pulse!...for an electro-mechanical relay. You got a link to the spec's?A latch relay may be what you are thinking of. They change with a 20ns pulse.
