The MPG306F is a three-pole double-throw (3PDT) Pushbutton Switch with single actuator and momentary operating function. The MPG series switch comes with silver clad contact base and silver clad with gold flash plated contact. The life expectancy depending on function (momentary) and number of poles from 40,000 up to 80,000 cycles at full load this is accomplished due to silver slugs in the contact area. In addition to the silver slugs all contact surfaces are gold flashed this inhibits oxidation and also offers a very low initial contact resistance. The design also includes over-moulded terminals which eliminate any voids which is possible with epoxy sealed terminals.
