Switches, Buttons, And Relays

Switches, buttons and relays provide the fundamental control points for electronic and robotic systems. Momentary and latching types let you select or toggle power sources, trigger functions, or detect physical contact, making them ideal for power‑routing boards, tactile sensors and user‑interface panels. They differ in contact rating, actuation style and mounting method – from miniature snap‑action levers suited to whisker‑type bump sensors, to slide or push‑button units that fit neatly on PCBs or breadboards. Relays add electrical isolation and higher current capability, allowing safe switching of motors or loads while preventing reverse flow. Compatibility with standard connectors and footprints, reliable contact performance and straightforward integration are the key factors that determine which device best matches a given automation or embedded project.
