WebThe “normal” status for a switch is the status its electrical contacts are in during a condition of no physical stimulation. Another way to think of the “normal” status is to think in terms of the switch being at rest. For a momentary-contact pushbutton switch, this would be the status of the switch contact when it is not being pressed. The National Association of Relay Manufacturers and its successor, the Relay and Switch Industry Association define 23 distinct forms of electrical contact found in relays and switches. Of these contact forms, the following are particularly common: Form A contacts ("make contacts") are normally open contacts. The contacts … list of german bands
