A method and apparatus for an electrical switch assembly generally comprising a snap-action electrical switch disposed in a module frame assembly and connected to electrical contact pins for mating with a contact pin connector. A switch module assembly is connected to the module frame assembly and includes a switch actuator assembly for actuating the snap-action electrical switch. The switch actuator includes a latch spring guide that may be configured for either 'alternate' or 'momentary' actuation of the snap-action electrical switch and emits audio and tactile switch status indicators perceptible to an operator. The module frame assembly and switch module assembly are releasably connectable to and form an integral unit with a cap base assembly having a cap module with a low power LED illuminatable display visible under extreme ambient lighting conditions for indicating switch status. The integral unit is interlockably receivable in a switch connector module that may include an electrical contact pin socket and is mountable in a bracket.
