The plastic and contact materials of the Series 44 range of 22-1/2-mm and 30-1/2-mm industrial control switches are free of potentially toxic cadmium based pigments, according to the company. In addition, the actuators, front/base adapters and switching elements are halogen free. The range is protected to IP65 from the front as standard, or alternatively for additional protection against extreme environmental conditions. The switches can be fitted with a protective silicon cap for a fast and simple upgrade to IP67, and are said to resist high levels of shock and vibration, making the switches well-suited to many applications in the machinery, process-control, panel building and lifting, and moving markets. The switches are rated at 500 V AC (10 A) and feature screw terminals with openings to guide a screwdriver, said to ensure safe handling of terminals. The switching elements feature high-quality, gold-plated silver, self-cleaning, double-breaking spring contacts, which are stackable. The series of switches include illuminated and non-illuminated pushbuttons and indicators, interlocking pushbuttons, emergency-stop safety switches, joysticks, potentiometers and rotary and keylock switches, available with a selection of accessories, including protective front rings, protective caps, blind plugs, enclosures, and legend plates.
