The Etronix power switch is a tiny MCU controlled on/off switch perfect for your r/c car. A simple push button operates the switch eliminating the problems associated with an ordinary mechanical switch and intermittent contact. The sealed unit is plastic and can easily be mounted to the transponder mount of your model or anywhere else you can mount it using double side tape.The switch also features a LiPo mode and by turning this on the switch unit will auto detect low LiPo voltage and cut off power to protect your LiPo from over dis-charging. This of course can be turned off if you have other safeguards in place or using Life/NiMH/NiCad battery. The switch can also indicate the remaining capacity within your battery via LED indicators.
