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.
