Automatic activators

Overview
An automatic activator is a Contraption that automatically triggers a POW, P-Switch, key, or another contraption upon loading. Usually, it uses a triggerer to start the contraption, but it is not restricted to using one.

Automatic question block triggerer
An automatic question block trigger automatically triggers a question block upon loading. It is made of a triggerer next to a question block. When the contraption loads, the spiky shell inside the spring will activate, bumping into the question block. Then, the question block will activate. As with any contraption featuring a question block, it is recommended to put a vine in the question block to make sure that the question block can be reloaded.

Automatic P-Switch triggerer
The Automatic P-Switch triggerer is very simple. Upon loading, the muncher will fall on the P-Switch, activating it. Unlike the automatic question block triggerer or automatic POW triggerer, it uses a muncher activator instead of a spiny shell-spring triggerer.

Automatic POW triggerer
The Automatic POW triggerer triggers a POW block upon loading. When the contraption loads, the triggerer makes the shell bump into the POW block. Then, the POW block will be triggered.

Automatic On-Off Switch triggerer
The automatic On-Off Switch triggerer causes an on-off switch to go from on to off or off to on. When loaded, the triggerer pushes the shell into the on-off switch. Then the shell will be removed with the empty off block. The on-off switch will be in the opposite state.

Sister classes
Timers and Randomizers can be activated upon loading.
