The BIG MOSFET SLIDE SWITCH HP by Pololu is an ultra-low-resistance, co-planar, single-pole-double-throw (SPDT) switch. This switch has a wide range of uses and can control high current, from 5A to 35A and at up to 40V. It is great for use in robotics, test bed applications, and other high-current applications. The switch has a robust sliding handle to provide a precise on-off switching capability, and can also be easily modified to meet custom applications. The fully-assembled switch is polarized and individually tested, with a heat-shrinkable protective cover available to maintain long term use and prevent shorts. Depending on the application, this switch also has mounting brackets, guides, and eyelets available to better ensure that it stays in place.
