The Bulgin Pushbutton Switches MC22LCBRG are single-pole, single-throw (SPST) switches with a normally closed (NC) contact configuration. They are designed for use in low-current applications, with a maximum current rating of 10mA at 12V. The switches feature a capacitive sensing technology, which allows them to detect a user's touch without the need for physical contact. This makes them ideal for use in applications where hygiene is a priority, such as medical and food processing equipment. The switches are also designed to be dust and water resistant, making them suitable for use in harsh environments.
