Comus International MH3

The MH3 is a mercury wetted switch designed for applications requiring reliable performance in high voltage and current scenarios. It has a maximum switching voltage of 1000 VDC or peak AC for resistive loads and can handle a maximum switching current of 2.0 A. The switch is rated for a maximum carry current of 3.0 A and a maximum contact rating of 50 W. The insulation resistance is specified at 10^10 to 10^14 Oc at 500 V and 25¬8C, ensuring robust electrical isolation. The switch operates effectively within a temperature range of -38¬8C to +125¬8C and can withstand storage temperatures from -40¬8C to +125¬8C. With a life expectancy of up to 1 million operations under specified conditions, the MH3 is suitable for applications that demand durability. It features a compact design with a glass length of 0.574 inches (14.6 mm) and a diameter of 0.106 inches (2.7 mm). The switch also exhibits good resistance to vibration and shock, making it a reliable choice for various engineering projects.
