The Electro-Mech Series 5100 provides momentary switching in a compact, 1.375″ behind the panel housing, saving up to 25% of usually required space needed by other popular models. These small switches are ideal for keyboard matrix assemblies and with their new recessed lens they offer even greater compactness and beauty.

Positive action, reliable circuitry, and proven low-bounce characteristics are offered in this fully enclosed aluminum housing design, ideal for tight packaging requirements and keyboard assemblies. Standard models are supplied with slide-action silver contact circuitry usually found in larger units. Gold plated contacts can be supplied for dry circuit applications.
