MPL 600 Series


MPL / Switches & Sensors 600 Series

The MPL 600 series provides robust and flexible SPDT snap action switching with custom set points ranging from 1.5 inH2O to 45 PSI. The SPDT micro switch adds a positive action with a mechanical differential from on to off. Miniature size and low cost make the MPL 600 Series ideal for OEM applications.


Ideal for heavier duty OEM applications, the 600 series provides higher current capacity / snap-action switching capability built on to the 500 series. Heavy current loads available from 3 amps to 25 amps in SPDT configuration.


Applications Include:

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