Panel Mounted section – Terminology Momentary switch – describes a single operation with a push to engage and an automatic release Latching switch – describes an alternate action with a push to engage and a further push to release Panel cut-out – the location point in the panel to mount the switch Lens – the colored actuator Contacts – the electrical switching element NO – normally open contact which is open in the non actuated position and closes a circuit on actuation NC – normally closed contact which is closed in the non actuated position and opens a circuit on actuation Enclosure types Europe IEC specifications 144 & 529 define the degree of protection provided electrical enclosures to safeguard personnel against electric shock and equipment within the enclosure from environmental contamination such as entry of water. This is expressed by the letters IP followed by two numerals. Definition Protection against solid objects greater than 2 mm Protection against solid objects greater than 2.5 mm Protection against solid objects greater than 2 mm and dripping water Protection against solid objects greater than 2.5 mm and dripping water Protection against solid objects greater than 2 mm and dripping water Protection against solid objects greater than 2.5 mm and dripping water Protection to IEC 44/855420 IP 20 NEMA (ventilated) www.ermec.com Bi-functional selection – feature to describe all latching pushbutton switches in the TP2 and TP5 series incorporating a simple selector mechanism to redertermine the function of the switch Exposed bezel – where the pushbutton lens fits inside the switch bezel Concealed bezel – where the pushbutton lens fits over the switch bezel Flush housing – for mounting switches with the minimum protrusion above the panel surface Raised housing – for mounting switches with the bezel prominent above the panel surface Snap-in mounting – for mounting switches into a panel from the front without the need of access to the rear of the panel, or without the use locknuts In the USA, NEMA and UL have established a rating system for enclosures which provides for different levels of protection. A direct comparison between IEC and NEMA is not possible but the following table gives an approximate guide. Protection to NEMA enclosure type NEMA Definition general purpose IP 30 NEMA general purpose IP 2 NEMA 2 (ventilated) drip proof IP 3 NEMA 2 drip proof IP 24 NEMA 3R (ventilated) rain proof, sleet (ice) resistant outdoor use IP 34 NEMA 3R rain proof, sleet (ice) resistant outdoor use Protection against dust and splashing liquids IP 54 – – Dustight and protected against water jets IP 5 NEMA 2 industrial use dustight & driptight Dustight and protected against heavy seas IP NEMA 35 dustight, driptight Dustight and protected against heavy seas IP NEMA 4 dustight, watertight Dustight and protected against water entry at one meter immersion Dustight and protected against heavy submersion IP 7 NEMA 4X dustight, watertight corrosion resistant IP 8 NEMA submersible watertight, dustight sleet (ice) resistant indoor & outdoor Protection against sleet (ice) not specified by IEC NEMA 3 oiltight & dustight 8 TH-Contact Products info@th-contact.com www.th-contact.com
