The AND Switch is a logic gate component of the RUST Electricity System. Facepunch added electricity components in the Electric Anniversary update on the 7th of December, 2018.
The AND Switch has two inputs on the bottom and one output socket on top.
Power will only flow through the AND Switch when energy travels to both sockets on the underside of the switch.
If just one socket is powered, no electricity will pass through.
When both sockets are powered, electricity will pass through, but only from the bottom socket with the most power flowing in. It will not combine the electrical sources.
You can use this to send enough power to activate a device in one socket and use the secondary socket as a trigger to receive power from a sensor device, such as the HBHF Sensor or the Laser Detector.
The energy conservation the AND Switch provides makes it ideal for sets of triggers that engage several other electrical components.
