Wed, 04/07/2010 - 6:54am
C&K Components has developed a new series of through-hole subminiature detect switches. Available with pretravel and overtravel, the KM1202 features a 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 0.4 A at 20 V AC or DC, while the silver-plated devices feature a contact rating of 0.25 A at 125 V AC or DC. Maximum contact resistance is 30 m-Ohms at 2 V to 4V DC for both the silver- and gold-plated contacts, and minimum dielectric strength is 1,000 Vrms. The operating temperature ranges from -30°C and +85°C. The RoHS compliant and compatible KM Series detect switches feature a pretravel measurement of 4.06 mm; total travel is 5.84 mm. Typical pricing ranges from $1.50 to $2.20 each.
