Our MERS gives you ON/OFF control of any onboard device. You can use it for lights, glow plug drivers, motors, smoke pumps, rocket igniters, solenoids, relays, and whatever else you can think up. The MERS is not proportional, which means it is either fully-ON of fully-OFF. The MERS performs the operation equivalent to a servo moving a mechanical switch back and forth, but in a much smaller package, and with no moving parts!
With the MERS, you have the option of using a seperate power source for your receiver and your ON/OFF device. The MERS is best used on a gear or auxiliary channel that allows you to flip a 2-position switch on your transmitter to control the ON/OFF operation.
