Completely fluorocarbon sealed switches are preferred for use in temperatures above 93°C [200°F]
4
Gold-plated contacts
NOTE: Same polarity each pole.
To order a fluorocarbon sealed switch, insert the letters Y and C into the catalog listing as follows. The LSA1A limit switch is changed to a LSYAC1A limit switch.
To order a low temperature, fluorosilicone sealed switch, insert the letters Y and B into the catalog listing as follows. The LSA1A limit switch is changed to a LSYAB1A
limit switch.
