DA123-F: Flush mounting setting switch push-button
These are a range of highly water-resistant final exit setting buttons, which use a magnetically-operated, sealed, dry-reed switch. The push-button diaphragm is a flexible moulding, and there is no metal spring to corrode or break. The push-button has a momentary operation and is available as flush or surface-mounting.
Connections are via an integral one-meter-long four-core, white fly lead. The flush mount version fits into a 30mm deep hole that is 19mm in diameter, supplied with a neoprene gasket and hardened steel zinc-plated fixing screws.
Available either "normally open" going closed or "closed-circuit" going open.
