Power Relays

The electrification of everything.

Replace your large, slow, unreliable EM relays with the Ideal Switch. Enable a new era of connected and better protected buildings (residential, commercial, hospitals, airports), transportation (eMobility, Rail, Marine), factories (Robots and Systems), and power distribution (solar, wind, grid, battery).

MM9200

Power Switch

The MM9200 is a high-power SPST micro-mechanical switch. The innovative Ideal Switch technology enables highly reliable micro-mechanical switches capable of carrying high voltage and high current in a small form factor. The MM9200 provides ultra-low on-state resistance and high off-state isolation, with greater than 1 billion switching cycles. Because of its long lifetime, extremely low current consumption, and small form factor, the MM9200 is an ideal solution for replacing electromechanical relays, as well as solid-state switches used for control applications where size, weight, power efficiency and thermal management are critical system-level design parameters.

MM9250

Smart Power Relay

The MM9250 is a highly-integrated, ultra-low resistance smart power relay using Ideal Switch technology. The relay reduces the size, weight and volume while integrating built-in monitoring, protection and controls into a low-profile surface mount package.

The MM9250 can handle AC or DC loads up to 300V and 10A and can be scaled to higher ratings.

High-power impact.

Switches do the heavy lifting to power our world, but current technology (transfer switches, contractors, and industrial circuit breakers, for example) are bulky, power-hungry and slow.

Reduced Size & Weight

Go from multiple bulky circuit breakers to small Ideal Switch boards. This means more than 85% reduction in size and weight for a higher density and smaller footprint.

Reduced Switching Speed

Go from 3-20ms to <10µs arc-free switching. 1,000x faster for safer, more efficient power management.

Reduced Power Consumption

Get rid of high power MOSFET switches. Go from 1.5W EMR, <60W SSR to <10W. That is 150x less power than EMRs, and 80% reduction from SSR for money saved.

Increased Power Rating

High-power handling of EMR in combination with the speed and reliability of SS. Works with all standard voltage ratings.

Increased Reliability

Go from <100K EMR cycles to 10B cycles for the lifetime of a solid-state switch.

Enabling Technology

Turn big things off when sensors signal they’re not needed, like street lights, production lines or building HVAC.

“The Ideal Switch is a tiny, efficient, reliable micro-mechanical switch with unmatched RF-performance and, counterintuitively, high-power handling of 1,000s of watts.”
