A 3 Second Timer is a timer that activates connected devices automatically, with a three second cool down. To use it, connect it and the desired device with Wires, and right click the timer, activating it. The timer will then function as specified.
The 3 Second Timer will not override the cool down period of the connected device. For example, if you connect a 3 second timer to a Heart Statue, the statue will still activate only once every ten seconds. In these cases it is usually more efficient to use a lower tier timer, such as the 5 Second Timer.
The 3 Second Timer must be placed on top of another solid block.
The timer itself can be wired to a different switch, which can be used to activate the timer, which will activate the connected device. A timer can even be wired to another timer, which will cause the timers to automatically turn themselves on and off.
