Electrical Characteristics of Tactile Membrane Switches
Voltage Rating: 35V (DC), 100mA, 1W;
Contact Resistance: 10Ω-500Ω (varies with different lead wires and materials used), typically <200Ω;
Insulation Resistance: ≥100MΩ at 100V;
Dielectric Strength: 250V RMS (50-60Hz, 1min), where dielectric strength refers to the maximum voltage a substance can withstand for one minute without breakdown. Exceeding this voltage may cause the material to break down.
Contact Bounce Time: ≤5ms.
Client Profile:
