SWITCHES
Standard Basic Switches
BZ/BA Series standard basic switches are used for simple or precision on/off
application needs. DT Series standard basic switches consist of two independent,
single-pole, double-throw circuits in one housing actuated by one actuator. The
terminals are separated by a non-conductive shield to reduce shorting.
Features
u
• Low operating force and differential travel
• Long mechanical life: up to 20 million cycles
at 95 percent survival
• Current rating ranges from 15A to 25A
• Momentary or maintained contact options
• Variety of actuating options and optional
sealed plungers
