Switches (Electronic)

Electronic switches designed for compact power control replace the bulk of traditional mechanical parts. Latching push‑button modules provide a single‑press on/off operation, keeping the circuit powered without a continuous physical contact. Slide‑actuated versions use an integrated MOSFET on the high side, delivering several amps across a wide voltage span while protecting against reverse polarity. Both formats mount directly onto a breadboard, making prototyping fast and tidy. Available in mini and larger footprints, they cater to projects that need different current capabilities, from a few amps for low‑power sensors to higher loads for motor drivers. Key considerations include the type of actuation, current‑voltage rating, reverse‑voltage protection and how easily the module fits into the existing wiring layout.
