Abstract

PURPOSE:To use a reed switch in common when the voltage and constant differ by storing a reed element in a detecting main body section, connecting the reed element to an inserting terminal, storing an auxiliary circuit having an indicating lamp and a contact protecting element in an auxiliary section, and connecting the auxiliary circuit to an inserting hole. CONSTITUTION:A detecting main body section 2 is fitted to a fluid pressure cylinder, and an auxiliary section 3 is fitted or removed to or from the main body section 2 by insertion. A reed element 15 and a magnet 16 in case of the core proximity type are stored in the main body section 2. The element 15 can be used regardless of the external voltage and constant, the main body section 2 can be used as a common component in any case, and only one kind of it is sufficient for use. The auxiliary section 3 is inserted into the main body section 2 and electrically connected to the element 15. An indicating lamp and a contact protecting terminal are contained in the auxiliary section 3, thus it is affected by the voltage and constant. Multiple kinds of auxiliary sections 3 are prepared for the voltage and constant to be used. The element 15 is connected to an external circuit via the auxiliary section 3, when a piston approaches to the preset region, the reed element 15 is turned on, and the indicating lamp is lighted.

The reed element of a reed switch that detects the position of the piston of a fluid pressure cylinder is originally a passive contact or a no-voltage contact that can be used regardless of the voltage or constant of the external circuit. When auxiliary parts such as protection elements are built in, components related to voltage and constants are built in, so the entire device becomes an active contact that is limited to voltages and constants.
