a one timer is when u have one boyfriend at one time okii stupid

it depends on if you mean a camera timer or an overall timer..

if an overall timer then yes.

if a camera timer then no, none of the blackberry's have a timer for your camera.

but if you go on app world and type in "nux shoot" you will get one, it is completely free and great.

Timer relays are used in control circuitry. There are two main types, an (off delay) and an (on delay).

If you want one device to turn off before the timer controlled device then you would use an off delay timer.

If you want one device to turn on before the timer controlled device then you would use an on delay timer.

When the timer is energized this starts the timer circuit in the relay to time out.

You can use the 555 timer to make a one minute solid state timer.

A one shot timer can be a great variety of many things. You could be referring to alcohol for example.
