I have convinced myself that a 20 amp switch mean it can withstand 20 amps flow during the on-off cycle. Once contact is made can a 20 amp switch pass through more than 20 amps? What's driving this question is my desire to use a switch, without a relay, to power/de-power my avionics buss. The current is less than 20 amps when turning the switched ON, but once ON the the transponder and VHF radio may occasionally take the load above 20 amps during simultaneous transmissions. Will this be a problem as long as the load is less than 20 amps during the switching cycle?
Thank You
