Use at voltage indicated for light. Wired to NO circuit. Upper temperature limit for lighted units is 93°C [200°F];
2
Plug-in listings include base receptacle

** These cat whiskers have a 140 mm [5.5 in] long actuator. To specify a 190 mm [7.5 in] length actuator, substitute -8B for -8A.
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.
