April 6, 2010 — C&K Components developed a 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 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.
Typical pricing for the KM Series subminiature detect switches ranges from $1.50 to $2.20 each in quantities of 2,500 pieces. Lead time is from 5 to 7 weeks.
