C&K has two new series of micro-mini, side-actuated detect switches. The FDSD and FDSE ranges are claimed to be one of the world’s smallest detect switches ideal for applications that need vertical side detection. The FDSD series of micro-mini side-actuated detect switches are provided in an extremely small package size of just 4.2mm x 3.6mm x 1.2mm, with optional flat or bent terminals that enable simple PCB mounting. The SPST-NO beryllium copper contacts have a resistance of less than 1Ohm and are rated for 10mA at 5VDC with a lifetime of 50,000 operations. The detect switch needs a maximum force of 40gf and can travel through an angle of 60-degrees or 3.05mm. The FDSE range adds an angled ability to the range. Housed in the same package size, the SPST-NC contacts are also beryllium copper and give a 50,000-operation lifetime. The contact resistance is less than 3Ohms and the electrical rating is 1mA at 5VDC. The angled detect switch needs a maximum force of 35gf and can travel through an angle of 60-degrees or 3.14mm. “We are constantly adding new solutions into C&K portfolio due to new market demands and needs of detect switches,” said Jeffrey Phan, global product manager, C&K. “The FDSD and FDSE switches provide a robust, reliable and price-competitive detect function in an incredibly small package.”
