The following statement is not applicable to Sealed Reed Relays or Mercury
Capsule Sealed Relays
"They spark when making or breaking contact and if some gas is near, it will
start combustion"
The statement is also not applicable to low level audio signals as an
example switched by a metallic contact.
DC current of 100ma or less can be switched with metallic relay contacts
without sparking. with the use of an RC Surge suppressor.
