MicroSwitch MP500 Series
A Subminiature microswitch of standardized small dimensions. The MP500 series stands out from other products on the market in terms of its mechanical service life and the choice of materials, wich enable it to resist temperatures up to 105 °C (221°F).
For applications with light forces of actuations as in pressostat, the microswitch can be delivered with a modified spring. The dimensional, electrical and IP protection parameters remain unchanged.
A variant without a protective membrane is available for use when the need for environmental protection (moisture and dust) is not necessary.
