Both delay-on-make timers and delay-on-break timers are classified as time delay relay systems. In other words, these components are considered control relay devices with time delay functions built in. Though both mechanisms are not typically noticeable, we see them quite often in everyday life. When you step through a door and a fan overhead turns on, you’ve activated a delay-on-make. If you’ve adjusted a thermostat or air conditioning system, you have encountered a delay-on-break. Electronic parts manufacturers label both systems under the same umbrella because the processes of these electronic part types are essentially the same, but the results differ.
Delay on make and delay on break systems follow this basic formula:
The temporary activation of a door fan is best equipped with a delay on make because the fan requires the power of a motor to start. A delay on make is specifically designed to prevent a motor or mechanism, from short-cycling. It stays on for a predetermined amount of time after the door closes, just in case someone enters soon after. This capability is accomplished through the time delay relay function of the delay relay functions.
A delay on break within a thermostat works a bit differently, it often depends on the engagement of a switch or button. When you adjust the temperature, there is a basic system that programs how long to delay the temperature adjustment. A delay on break is the activator in the thermostat that gives it the ability to adjust temperature periodically. The delay on break plays an integral role in this process, as it allows you to reset the timer if the external or normally open switch (N.O.) is activated for a consecutive time.
Overall, these useful little components enable much of our convenient day to day devices. Time delay on make and time delay on break mechanics, in terms of making it or breaking it, certainly make it as electronic parts that have aided in the advancement of today’s electronic technology.
