Alright, so living with 4 other guys in a 2 bathroom house can be harrowing. Especially on an evening where beans were on the menu. We make liberal use of the ventilation fans in our bathrooms, but many a time I’ve woken up to find that the last user of a bathroom left the fan on after they left, and then it ended up staying on all night.
So here it is. Here’s how I’m going to be rich and famous. All I need is a very simple circuit with a timer.
If your bathroom light is on, and the fan is on, it remains on indefinitely. However if the fan is switched on and the light is turned off, the timer triggers and it runs for 5 minutes before turning the circuit off and flipping the switch back to the off position.
Get it? You see it? This is world changing. This is a Home Depot must! I’ll be in Lowes! I’ll be in Home Depot! I’ll be Wal Mart!
It’s not exactly the same thing, but they do make a timer switch that would turn the fan off after a certain amount of time. You don’t flick the switch. Rather you turn the dial and it can be a time anywhere from 5 minutes to an hour. The electricity flows for that amount of time then it turns off. It’s kind of like the timer on your clothes dryer.
