Hard to know what you are meaning?
A timer is a device in a circuit that switches on then off at given times. There may be many on/off operations not just the one.
Think of some lights, say street lights that come on at a certain time then off at a later time. If they are electric that would fit you question.
Although the lights are more likely controlled by darkness at dusk and first light in a morning.

What would happened if you wired a 240v ballast and a 120 v ballast into a heavy duty timer?
The timer has to be multi-pole. The ballast must be connected to the load contacts of the timer. If the timer is a 120 Volt timer, the timer has to run on a 120V. circuit. Loads are loads, and as long as you have a multi-load timer you can hook up whatever you want. If the timer only works on a shared power source (load shares the timer supply) you will need to use a contactor on the load side or the timer.
What is the Electrical supply IN THE UK?
Home electrical service in the UK is 230 volts at 50 hertz.
What are the three factors that effect the electrical parameters of a op-amp?
Supply voltage , temperature , frequency are factors that effect the electrical parameters of opamp
What point in an electrical circuit that is connected to the negative side of a power supply is called what?
battery
Who do you contact to have mains electric cable laid to your property?
The electrical supply authority for your area
Where should a timer be installed - at the electrical outlet or the end of a power cord?
The outlet would be the more often recommended place for it.An electrical timer can be placed anywhere within the circuit. Usually the timer would be placed at the front end of the circuit.
Can an electrical timer be used to control on and off power to self ballast lamps?
Yes, an electrical timer can be used to control the on and off operation of the power to self ballast lamps.
Where can one buy an electrical supply box?
Electrical supply boxes can be found from a local electrical warehouse or else try a good electrical supply store online, before you buy it should consult with a registered electrician.
What is the function of electrical socket?
Its function is to supply electrical power via a plug that is plugged into it to supply an appliance.
Which electrical test requires the supply to be energized?
Testing of an electrical circuit for voltage requires the supply to be energized.
What type of resistance would exist for electrical timers?
none the resistance is in the wire not the timer

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 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.
On a WC macerator installation the electrical supply to the unit should be wired from?
On a WC macerator installation the electrical supply to the unit should be wired from a switch.
Can a 12 volt light be run on a 120 vac timer switch?
No and yes. A 120-volt plug-in timer connects the line voltage to the timer and to the switch that is operated by the timer, so you can't use it directly for a 12-volt light.However, if you use the timer to supply power to a step-down transformer, you can run a 12-volt light off the transformer (that's how most low-voltage landscape lighting timers work). If you don't need much current, you could even plug a 12-volt AC adapter "wall wart" into the timer. Otherwise, you would have to open the timer and modify it so that the micro switch is completely isolated from the 120-volt supply and bring it out to connectors for a 12-volt supply. Make sure you know what you're doing and also don't exceed the current capacity of the switch.
Do electrical wires affect the voltage?
electrical wires are selected to satisfy with the desired conditions and supply.
