Why is a timer is used in an electrical circuit?
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.
How does an off delay timer work?
when off delay timer gets control signal, its NO(NORMALLY OPEN) contact become NC(NORMALLY CLOSED) for preset duration, and then become NO.
What is ON delay and OFF delay timer?
with an ON delay timer once the power has been appied to the timer unit, the timer contacts will change state-open/close after a preset time (for example A&B timers are adjustable anywhere from 0.05 seconds to 300 Hours) with a OFF delay these contacts change state after the power to the unit has been removed then the preset time will time out (this count dosen't start until the power is removed

How do you wire a timer switch to a 3 way light switch?
First you need to decide what you are trying to accomplish. You can wire the Timer switch in series with or parallel to the 3-way switches. If in series then the 3-way switch function would depend on the timer state. If the Timer switch was ON then the 3-way switch could turn the connected device ON or OFF from either location. If the Timer switch were OFF the device would be OFF no matter what you did with 3-way switches. To wire in this fashion put the timer between the supply and the input to the switches. If the Timer is in parallel then if the Timer is ON it doesn't matter what you do with the 3-way switch, the device will be ON as long as the Timer is ON. If the Timer is OFF then the 3-way switches will work in their normal fashion. To wire in parallel connect the supply to one side of the Timer and the device to the other.

Is there a separate relay or fuse for the intermittent delay for the wipers on a 97 jetta your hi and lo wipers work but not the delay?
the delay on jetta wipers is different. the delay is adjustable. if someone set the delay very long, you will think the delay is not working. here's how to shorten the delay. turn the wipers to delay (one click DOWN on the stalk). immediately turn it back off and now turn it back on. the delay is the length of time you had the wipers off between the two on's. for a 3 second delay, turn the wipers to delay, immediately turn them off, wait three seconds and turn them back on. for a 6 second delay, turn them on, immediately turn them off, wait 6 seconds and turn them back on.
