The 1PB43 is a momentary action, panel-sealed pushbutton switch featuring a single SPDT circuit and a red, round button. It is designed with a flexible leaf actuator for lower operating force and shorter button travel. Sealing is achieved via an elastomer seal between the actuating plunger and button collar, and an O-ring at the panel front. The switch is rated for 5 amps at 30 VDC (resistive) or 5 amps at 125/250 VAC. Its two-piece design allows the switch unit to be wired and then snapped into the separately mounted button assembly from behind the panel, simplifying installation.
