Limit switches
are designed to interlock the mechanical motion or
position with an electrical circuit. The limit switches are
highly suitable for hoists cranes lifting platforms and
other such machines. Though available with up to four pole
configurations, most common limit switches are single pole
contact block having one NO and NC set of contacts.
Limit switches also are available with time-delayed contact
transfer, which are highly useful in detecting jams. A wide
selection of models is available including greater OT models,
indicator-equipped models, low-temperature models,
heat-resistant models and corrosion proof models. Limit
switches feature a neutral-position or center-off type
transfers. |
