12 Series switches are ideal for operation in harsh explosive environments where space is at a premium. A snap-action Belleville spring assembly is used to provide vibration resistance and prolonged switch life. A hermetically sealed switch and stainless steel enclosure provide ruggedness and protection from the environment. The 12 Series is approved for use in hazardous locations worldwide, from offshore oil rigs to process and energy applications, to protection of capital equipment.","Triple approval (UL, cUL and ATEX) means the 12 Series meets the demanding requirements of hazardous locations. It can be used in a wide variety of applications where space is at a premium. Ambient temperatures can be as low as -58°F (-50°C) or as high as 203°F (95°C). All metal wetted parts comply with NACE MR-0175. The stainless steel design and enclosure type 4X rating assure long-term performance in the toughest applications.
