Keypad switches are human interface modules with a button switch matrix for direct user input to a CPU, microcontroller or keypad controller and may include a display for user information and instruction. Keypads are selected by the column and row matrix, number of keys, legend, dimension and mounting type. Output types include CAN Bus, matrix, independent switch contact (parallel), onboard controller output, USB and Weigand.

Compare SPST and SPDT toggle switches, understand AC/DC ratings, and follow wiring examples. Check contact action, mounting and parts in the ChipApex catalog.
