Dwyer Instruments 201-WT-7810-C1-60

Long life and reliable operation is inherent in the design of the 201 series. The use of an external magnet reduces the possibility of magnetic particle build up inside the armature tube and subsequent loss of operation as may occur with the internal magnet repulsion design. Electrical requirements are met by use of hermetically sealed snap action or mercury switches in a variety of actions including SPST, SPDT, DPDT and DPST arrangements. Optional circuits are available for low current/voltage DC, high current DC, or high temperature applications.
