Series 194/195 DIP

Side actuated,

through hole

DIP switches

Features

Optimized Mechanical Features

• SPST switching functions

• Enclosed actuators shield contacts from

foreign particles throughout life of switch

• Reliable tape top seal optional/bottom epoxy seal

standard

• Standard 2.54mm (.100") x 7.62mm (.300") DIP centers
