How to Place Actuators in Terraria
First off, you're gonna need to get your hands on some actuators. Swing by the Mechanic NPC and buy a bunch; she's usually found chilling in the Dungeon after you rescue her. Once you've stocked up, just slap those actuators directly onto the blocks you wanna make toggle-able. Remember, you control them with switches or levers, so don't forget to hook everything up with wires. The Mechanic sells those too, so grab some while you're at it.

Don't overthink it. Actuators go on blocks, wires connect them to switches. That's it.
Honestly, just buy a bunch, place them on the blocks, connect with wires, and enjoy the magic. It's like Lego but cooler because you get to hide and reveal stuff with a flick of a switch!
It's super simple! Just put the actuator on the block you want to move and then connect it to a power source like a switch or a lever with wire. Bam, you're an engineer!
