Switches

Switches are electromechanical components that control current flow through manual or physical actuation. This category includes tactile switches, pushbutton switches, toggle switches, rocker switches, slide switches, DIP switches, rotary switches, keylock switches, reed switches, snap-action/micro switches, and emergency stop (E-stop) switches. Key parameters: contact configuration (SPST, SPDT, DPDT, 3PDT), current/voltage rating, actuator type and force, mounting style (through-hole, SMD, panel mount), IP rating (for sealed/dustproof/waterproof), and electrical life (number of cycles). Illuminated switches integrate LEDs for status indication. Automotive-grade switches meet AEC-Q200 reliability standards. Popular manufacturers: C&K, NKK Switches, Omron, TE Connectivity (ALCOSWITCH), E-Switch, Apem, Grayhill, and Carling Technologies.
