Conveyor Belt Safety Pulls Switches are designed to provide a switching mechanism that is capable of isolating a power to the drive station of a conveyor belt in an emergency condition. The cable pull switches are actuated by lanyard cable that interconnects a series of pull switches. This arrangement provides a continuous emergency tripping mechanism that is available at any point along the length of the conveyor. In the event of a cable being pulled, the pull switch trips and latches the trip thereby de-energizing the conveyor start contact via an electrical interlock. The mechanical latch may only be released at the respective pull switch via a reset knob. Each switch is double ended and thus provides a tripping mechanism on both sides of the switch. Regulation requires that operators and personell in the vicinity be warned before a conveyor belt is started. The intelligent cable pull features two integrated pre-start sirens as well as two LED’s that provide audio and visual warnings. The LED also provides trip device indication.
