Rees 04966-200 Explosion Proof Switch with Actuating Arm & Broken Cable Detection, 2 (NO/NC) SPDT

Features:

This taut cable switch is equipped with a positive safety lock and broken cable option. Once actuated, it cannot be accidentally reset causing dangerous equipment to restart. The broken cable option feature ensures actuation even if the cable is broken or cut.

There is one electrical connection inside eliminating the double electrical connections typically required in two ended units employing a separate micro switch for cable in each direction. This style has extension springs (included with switch), attached to opposite ends of the pull cable, which maintain the cable under constant tension.

The switch is mounted so that it is centered between the end springs which minimizes any cable length changes caused by temperature changes. The operating handle is held in the center vertical position with the internal switch in a normally closed condition. If the cable is pulled or breaks, the handle rotates to release the switch lever. The alarm signal is generated for either condition. The operating handle must be manually reset back to the center position after the cause has been corrected.

The standard construction of these switches consists of the corrosion resistant aluminum housing complete with stainless steel hardware, red powder coated actuation handle and stainless steel actuation shaft.

• Recommended cable length is 100 feet maximum on each end
• Can be mounted in any position

The cable should be supported by eyebolts every 10 feet to ensure that the weight of the cable alone will not actuate the switch.
