The following switch is a hand operated, control circuit device, rated ‘Heavy Duty’ normally for use with electromagnetic equipment.  The body is made from die-cast zinc.  The red mushroom ergonomic shaped plunger is molded from DuPont Delrin 100ST Acetal for improved impact resistance and is solid color throughout.   


  • UL/NISD E357870*
  • Nema 12/13, IP 65


The operator will accept up to three tiers of two contact blocks for a total of six separate circuits.  Each operator is supplied with all mounting hardware and a solid neoprene rubber gasket which provides an oil tight seal upon installation.  The mechanical life of this unit is 1,000,000 operations. 


This device can be found on a variety of machinery, used to perform such operations as  ‘stop’, ‘top stop’, ‘inch’, ‘jog’, ‘off’, ‘forward’, ‘reverse’, etc.


This series satisfies the requirements of IEC 60947-5-5 – 3.9 direct opening action (positive opening action) (of a contact element); when fitted with one or more of any of our normally closed contact blocks.  This is commonly referred to as “Positive Break”, meaning the breaking of the normally closed contacts is not dependent upon springs.


*UL/NISD E357870 when fitted with; 50702, 50703, 50716 (shall not have any contact blocks stacked on top of it), 51703, or 52702.
