Rees 2.25 Inch Mushroom Plunger with Spring Latch Switches comply with IEC/EN 60947-5-5 for Emergency Stop Applications, #11 NC-NC Positive Break Contacts

Features

The following NEMA 12/13, IP65 switches are hand operated, spring latchable, control circuit devices, rated ‘Heavy Duty’ normally for use with electromagnetic equipment. The body and some of the plunger heads are painted with a dry powder paint, and made from die-cast zinc. The plastic plungers are molded from DuPont Delrin 100ST Acetal for improved impact resistance and are solid colors throughout. Each captive terminal will accept (2) #14 AWG stranded wires and the contacts are gold plated to eliminate high resistance tarnishing. Each switch is supplied with mounting hardware and a solid neoprene rubber gasket which provides an oil tight seal upon installation. The mechanical life of these devices is 500,000 operations. These switches can be found in a variety of uses on industrial machines. Presses and press brakes use them as “STOP” buttons. The switches marked BY-PASS are designed with the normal operation of one NO and one NC, when the switch is “Locked Out” BOTH sets of contacts are closed producing an electrical by-pass condition. This switch is normally found on multiple operator presses. The red plunger “Positive Break” styles comply with all standards for ‘emergency stop’ applications. The plated steel latch plate has either a 0.29" dia. hole for insertion of a multi-padlock hasp or a .31" hole for insertion of a padlock. Five devices have had the padlock hole omitted, see the chart on following page.
