Application
Series 54 switches are designed to serve as pilot controls for magnetic reversing starters and contactors which in turn make and break full voltage between
line and load. Contacts in the switch are operated when the external shaft is rotated. For the switch to perform a pilot control function, the contact must be
wired in series with the coil circuit of a magnetic reversing starter or contactor.
The shaft may rotate in either direction. When tripped, if rotation direction is reversed, the contacts will reset in 1/4 to 1 1/2 turns, depending on shaft-to-cam
ratio. Switches with Long Dwell Cams are available. These cams provides for the contacts to be actuated for a longer period of time as might be required in
hoist or similar applications.
Fine adjustment cams are also available. This feature increases accuracy in setting the number of turns to cause the contact to operate.
