C&K Components, a leading international supplier of tact switches, toggle, rocker and pushbutton switches, and smart card interconnect devices, has developed a new series of through-hole subminiature detect switches. Available with pretravel and overtravel, the KM1202 features a highly reliable contact design with a minimum electrical life of 10,000 actuations at full load.
“The KM1202 switches feature a reliable SPDT contact design with overtravel making this switch perfect for enclosures,” said David Webber, director of product management for C&K Components. “The subminiature size along with the reliable contact design make the KM Series detects ideal for use in enclosures, server blades, alarm systems, computers, and other detector switch applications.”
The KM Series detect switches are available with gold- or silver-plated contacts. Maximum contact rating for the gold-plated switches is 0.4A @ 20V AC or DC, while the silver-plated devices feature a contact rating of 0.25A @125V AC or DC. Maximum contact resistance is 30mΩ @ 2 to 4V DC for both the silver- and gold-plated contacts, and minimum dielectric strength is 1,000Vrms. Operating temperature ranges from -30°C and +85°C. The RoHS compliant and compatible KM Series detect switches feature a pretravel measurement of 4.06mm. Total travel is 5.84mm.
