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.

Standard basic switches

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
