Heres the setup:
1. I have standard household current (110v, 15 amp, AC) entering into
a device.
2. A momentary pushbutton switch is pressed.
3. This feeds a current to a standard receptacle outlet, activating a
light.
4. The switch is released.
5. Power is cut off to the light.
Here is what I want to accomplish:
1. When the pushbutton switch is released, the current flow to
the receptacle continues for an adjustable amount of time (ex: 4
seconds to 10 minutes).
-------------------------
Motion sensors from any hardware store do this same thing. They have a
switch to select 4 seconds, 10 minutes, or 20 minute activation. They
are typically hooked up to a light socket or sold individually for a
little as $10. I have found "AC Relay timers" on industrial supply
sites, but they cost upwards of $50 and are very large units
themselves. I don't need motion of proximity sensor capability since
the device it switch activated. I simply need to keep current flowing
for a length of time after the momentary switch is released.
I guess, as a last resort, I could buy a motion sensor, disassemble
it, and somehow bridge the motion sensor part. However, I'm hoping to
accomplish this with premade unit of some kind, and for under $10
(since ill be making large quantities.)
So, does anyone have any ideas of suggestions?
Thanks
