PULL WIRE SWITCHES
The Pro-Line Safety Cable Pull Switch is used as an emergency shutdown device for conveyors or other equipment. They meet OSHA and MSHA requirements for safety shutdown devices. Safety pull cables are attached to the actuating arm of the switch. When force is applied to the pull cable it rotates the actuating arm and actuating shaft. At a 20° rotation the switch enters a tripped and locked position. The actuating shaft has two cams inside the housing. Each cam simultaneously actuates an independent SPDT micro-switch for shutdown and alarm signals.
The Safety Cable Pull Switch has one housing layout that may be used interchangeably in mid-run or end-run positions of the safety pull cables. Standard Safety Cable Pull Switches include a manual reset lever. This lever keeps the switch locked in an alarm condition until it is manually reset by an operator.
