The 7105TZQE is a single-pole momentary-off-momentary (Mom-Off-Mom) miniature toggle switch from the C&K 7000 Series, designed for applications requiring momentary contact closure in both directions with a center-off position. The switch features gold-plated copper alloy contacts with a contact resistance below 10 mO typical at 2–4 V DC and 100 mA, ensuring reliable electrical performance. It operates over a temperature range of -30°C to 85°C with an insulation resistance of 10? O minimum and dielectric strength of 1000 Vrms minimum at sea level. The switch is rated for 40,000 electrical cycles at full load and includes an epoxy terminal seal compatible with bottom-wash PCB cleaning methods. Common applications include control panels, instrumentation, and consumer electronics where compact, reliable momentary switching is required.
