SWITCH INTEGRATED CONTROLLER FOR ENERGIZING AN EXTERNAL ELECTRICAL DEVICE

摘要

A switch integrated controller capable of giving a wide variety of controllers at a reduced cost. The controller has a casing composed of a controller module and a terminal module which are separately formed from each other and detachably connected to each other. The controller module has an entry section for receiving a specific external condition and a signal generating section which generates a trigger signal when the specific condition is met by a predetermined reference. The terminal module includes at least one pair of terminals which are adapted to be connected through wires to the external electrical device and an associated external power source and further includes a relay switch which is connected between the terminals for selectively connecting and disconnecting the electric device to and from the electrical power source in response to the trigger signal. Thus, the terminal module including the relay switch can be made common to different kinds of the controller modules and can be assembled with the controller module into a single unit only at an expense of simple mechanical connection between enclosures of the respective modules and electrical connection between the switch relays and the signal generating section. With this result, a wide variety of controller units of different functions can be fabricated at a reduced cost.
