Description
INDUSTRIES SYNDICATE’ make limit switch, lever operated spring return, continuously rated for 40Amps at 440V, 50 cycles, with four pairs of normally closed contacts. Moving crane pushes the lever at the limit of travel and opens two pairs of contacts in two phases thus disconnecting power supply require for motion in the same direction, but at the same time providingconnection for reverse motion. The switch is contained in a sheet metal encloser with cast iron top and bottom cover and suitable for plain cable entry. Over-travel trip is bi-directional with backing out.
Travel shunt limit switch, mill duty type, spring reset, rated for 10amps, at 440V, 50 cycles, (or 2.5 amp. D.C. non-inductive at 220-V.) 2pairs of silver-tripped contacts, 1 N.O. & 1 N.C., in dust-tight cast-iron enclosure, insulation level 660V.
Various lengths and shapes of lever roller arrangement are also available. Hoist Limit Switch, dead weight operated & counter weight reset, type H-50C, with 2 pairs of contacts rated for upto 50 amps, at 440V, 50 C/s, normally closed under counter-weight predon…over dead-weight but opening in the event of suspended counter-weight being pushed up, snap-action type in M.S. sheet metal enclosure, complete with counter-weight & rope. Insulation level 660-V.
Spindle type Hoist/Lower Limit Switch, type LH4S, with 4 pairs of contacts, normally closed, two pairs opening at the limit of travel in one direction, and the other two pairs opening at the limit of travel in the other direction, but providing circuit for reverse motion in each case, in cast iron enclosure, contacts rated for 20 amps, at 415 volts 50 cycles, maximum revolution of the spindle for directional trip from end to end in 40, adjustable to lower value.
