Series Limit Switches

Limit switches in seriesSometimes referred to as "overtravel limit switches" these devices are designed to carry the main power supply to the machine. They can be arranged to firstly slow the machine as it nears the limit of travel, and then to stop the machine when it reaches the limit; here the main supply is broken by the switch contacts, thus causing a complete stoppage.

These switches are ideal for ensuring the safe operation of heavy mechanical handling equipment, such as cranes etc.

Schneider Electric Series Limit Switches

Ultimate Limit Switches

Ultimate limit switches are positioned to provide a backup safety system whereby, in the event of the first limit switch failing, they serve to break the power supply to the machine, bringing it to a complete stop. Once the ultimate limit switch is tripped, the machine cannot be driven until the system has been reset and confirmed safe for use.
