The following switches are hand operated, control circuit devices, rated ‘Heavy Duty’ normally for use with electromagnetic equipment. The body is made from die-cast zinc. The zinc plated ring eye operator is also made from die-cast zinc. The mushroom ergonomic shaped plungers are molded from DuPont Delrin 100ST Acetal for improved impact resistance and are solid colors throughout. Each operator will accept up to three tiers of two contact blocks for a total of six separate blocks. 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 these units is 1,000,000 operations. These devices can be found on a variety of machinery, used to perform such operations as ‘start’, ‘stop’, ‘top stop’, ‘inch’, ‘jog’, ‘on’, ‘off’, ‘forward’, ‘reverse’, etc.
The 40102 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 in not dependant upon springs.
Recommended cable length for the 40050 series is 33 feet.

Designated switches have been certified as Emergency Stop Pushbuttons and are listed under UL/NISD File E357870, Sec. 1. These switches were evaluated for NISD mounted in a UL type 12/13 enclosure.
