The 97C04ST is a surface mount DIP switch from Grayhill's Series 97 featuring 4 positions with half-pitch spacing and a low-profile design that is half the size of standard DIP switches. It offers electrical ratings of 25 mA at 24 Vdc switching and 100 mA at 50 Vdc non-switching, with a maximum contact resistance of 100 mO and insulation resistance of 100 MO minimum at 100 Vdc. The switch operates over a temperature range of -40°C to +85°C, has a mechanical life of 1,000 cycles minimum, and withstands mechanical shock of 50G's per MIL-STD-202F. Its compact form factor and low mass make it ideal for applications where space is at a premium, such as notebook computers, hand-held radios, industrial control products, CD-ROM drives, and cellular base stations.
