An electrical switch includes two fixed contacts and a moving contact supported for movement between an ON position in contact with the fixed contacts and an OFF position out of contact with the fixed contacts, and an operating mechanism for moving the moving contact. The lid is removably attachable to the housing. From the predetermined monitoring location, the predetermined information is provided to other network monitoring devices at one or more other network locations. This allows the front panel to act as an interactive touch display system. The current flowing to the first transistor is supplied to the nonlinear amplification circuit.
