Hello I was wondering if anybody had any rule of thumbs or ideas on how to size either a capacitor or diode or both for protection on a relay contact. At work we have a lift machine, roughly 15 feet vertical and the contactor circuit for the dc brake on the motor sometimes sticks so therefore the lift slams to the ground very randomly nearly killing operaters. I'm looking to prevent this by shunting a capactive, diode circuit across the contacts. The voltage is 120ac. Thx for any info.
