Foot Switches suited for heavy-duty application such as Machine tools, Rubber & Tyre making machine, SPMs, Welding machines.

Foot Switches are designed to open and close AC or DC pilot circuits. The contact mechanism has Single Pole Double Throw-twin break, silver contacts 1 NO + 1NC enclosed in moulded phenolic block.

BCH Foot Switches are designed to open and close either AC or DC pilot circuits. The contact mechanism has single pole double throw twin break, silver contacts 1NO+1NC and double pole double throw 2NO+2NC Contacts and is completely enclosed in moulded phenolic block. The contact block or blocks are mounted in a watertight and oil tight enclosure. Smartly styled and compact enclosures have silver-grey hammertone baked enameled finish inside and outside. Three point mounting bosses on the treadle operated switches assures stable mounting on uneven surfaces.

These heavy duty foot switches are two position, or three position spring return, front treadle operated. Pressure on the treadle closes the normally open contacts and release of the pressure returns the contact to original position. The lever assembly provides for adjustment of treadle travel to operate the contacts.When two contact blocks are supplied, adjustment of the lever assembly provides for simultaneous or differential tripping (second stage operation) of the contact blocks. The contact assembly(a precision limit switch) is fastened to the bottom of the case with the terminals up for easy wiring.

Treadle latches when supplied permit spring return or maintained contacts operations. The latch release pedal provides easy-on-the-job conversion from maintained contact to spring return. Conversion to spring returns requires only a push down and forward motion on the latch release pedal to make the treadle latch inoperative. The latch release pedal is normally located on the right hand side, it can be converted in the field to left hand extension.

The watertight and oiltight enclosure has a cast cover and treadle. Agasket between case and cover and a friction type seal on the treadle shaft assures watertight and oiltight performances.
