MPL 600 Series


MPL / Switches & Sensors 600 Series

The MPL 600 series provides options for robust and flexible SPDT snap action switching, with set points from 1.5 in/H2O to 45 PSI. The SPDT micro switch adds a positive action with a mechanical differential from on to off.


MPL 600 Series switches offer pressure or vacuum sensing which combines the features of the MPL 500 Series with snap action switching for higher current capacity, SPDT contact form and switch dead bands (also referred to as mechanical differential or hysteresis). Miniature size and low cost make the MPL 600 Series ideal for OEM applications.


Applications Include:

Pressure and vacuum sensing with snap-action switching for higher current capacity, SPDT contact form and switch dead bands.
