Cable-Pull Safety Switches

Safety switch, cable-pull interlock operated

Cable-Pull (Grab-Wire) safety rope switches are designed to be mounted on machines and sections of conveyors which cannot be protected by guards.

In contrast to traditional mushroom head type emergency stop buttons, Cable-Pull Safety Rope Switches can initiate the emergency command from any point along the installed rope length and provide robust emergency stop rope pull protection for exposed conveyors or machines.

• All have a positive mechanical linkage between the switch contacts and the wire rope. The switches have rope breakage monitoring.
• On pulling the rope, anywhere along the length, the safety contacts are positively opened and the auxiliary contacts are closed.
• The switches are mechanically latched and can then only be returned to the operational condition by pressing the blue reset button.
• An optional 2 color LED indicator is available to enable switch status to be viewed from a distance.

These safety interlock and safety limit switches are developed and manufactured according to IEC and EN European standards and are UL listed for Type 4 machine safety/ OSHA machine guarding.
