Series B A Rockers Distinctive Characteristics Toggles Process Sealed Subminiature Antistatic Toggles Pushbuttons Subminiature size saves space on PC boards. Specifically developed for logic-level applications. Programmable Illuminated PB Antistatic superstructure, consisting of the carbon impregnated bushing and the support bracket, prevents static discharge to the contacts. Static electricity from an operator’s touch travels from actuator through the bushing and bracket to the PC board.
