The Model SS-3 Pull Cord Switch is a conveyor safety accessory designed to interlock with the conveyor shut down systems in the event of maintenance or an emergency. When force is applied to the cable on either side of the switch the actuator arm rotates and locks in the alarm position. This activates two (2) micro switches and the manual lock out. Once the maintenance is done or the emergency is cleared the switch can be reset by pressing down and releasing the manual reset lever. Model SS-3 Pull Cord Switches are typically mounted on the walkway side of the conveyor or in situations where the conveyor is accessible from the ground. The SS-3 Pull Cord Switch can be ordered in standard and CSA approved versions. The CSA approved version is also approved for Class II, Div. 1 & 2, Groups E, F & G.
