The 5637MAB27 is a single-pole momentary-off-momentary toggle switch from APEM's 5000 series, featuring a threaded bushing design with solder lug terminals. It is configured with a Ø 11.9 mm (15/32) threaded bushing (5600M series) and includes a standard lever actuator with keyway. The switch has an overall height of 17.50 mm (0.688 inches), a lever length of 11.00 mm (0.433 inches), and operates with momentary contact in both up and down positions, returning to center off when released. This configuration is ideal for applications requiring momentary switching action with reliable solder lug connections for permanent PCB mounting or panel integration, with optional K sealing available for enhanced environmental protection.
