Introduction The MPL 2000 is a rugged, low-cost pushbutton switch, suitable for a wide variety of general purpose switching applications such as indicating a door opening, detecting a device limit, or switching off power when an appliance panel is removed.   Incorporating a robust, snap-action mechanism, MPL 2000 is capable of switching loads up to 21A. Fine silver contacts ensure high reliability and long life.   MPL 2000 is self-mounting. Locking tabs hold the switch in place in a 0.55" x 1.125" panel cutout.   At rest, the standard pushbutton extends 0.875" from the mounting surface. Custom configurations are also available in OEM quantities.
