Switch debounce circuit uses only one gate
https://www.electronics-lab.com/switch-debounce-circuit-uses-only-one-gate/
The circuit in Figure 1 produces a single debounced pulse each time you press S1. Moreover, the circuit uses only logic power from the remote pull-up resistor, R2. You can use the circuit to detect when a key is pressed in a non-energized device, such as a device in a system that’s just coming up from […]

https://www.electronics-lab.com/texas-instruments-tmux6219-single-channel-21-spdt-switch/
Texas Instruments TMUX6219 Single Channel 2:1 (SPDT) Switch is a complementary metal-oxide semiconductor (CMOS) switch in a single channel, 2:1 (SPDT) configuration. The device works with single supply (4.5V to 36V), dual supplies (±4.5V to ±18V), or asymmetric supplies (such as VDD = 8V, VSS = –12V). The TMUX6219 supports bidirectional analog and digital signals […]
Elektor Project: Wi-Fi for LoRa Switch
https://www.electronics-lab.com/elektor-project-wi-fi-for-lora-switch/
Clemens Valens @ Elektor Labs writes: We published a remote-controlled switch in the March/April 2020 edition of Elektor magazine. It had state feedback and communicated using LoRa. Because it was housed in a waterproof IP66 enclosure, it was suitable for outdoor use. It was also a modular project with the relay and power circuitry on […]
