Beschreibung
Zusammenfassung:	PURPOSE:To enable the solenoid operation by a sequence controller and make a supplementary relay circuit and the like unnecessary by a method wherein a driving part of a controller, which is operated by the electric signal from a pneumatic solenoid switching valve, a hydraulic solenoid switching valve and the like, is composed of a solenoid and a non-contact switch is fitted to the solenoid in a unitary body while being made freely removable. CONSTITUTION:A non-contact switch 7' is fitted to a solenoid B' in a unitary body but freely removable and signal input terminals 8' and AC output terminals 10' are drawn out of the switch 7'. Then the terminals 10' are connected to source input terminals 11', which compose the solenoid B', so that a solenoid D with a non-contact switch is composed. When the signal from a sequence controller is applied to the terminals 8' of the switch 7', one of the terminals 10' is connected to one of the terminals 11' through the solenoid B' and another terminal is connected to another one of the terminals 11' directly. In this composition, plug-in method is introduced for the connection of the terminals 10' in order to make replacement easy when any one of the components generates trouble.
