Data Sheet

The Pololu RC Switch with Medium Low-Side MOSFET [https://www.pololu.com/

product/2803] has an integrated low-side MOSFET that allows it to drive moderate loads

(up to around 15 A) and a voltage regulator that allows more options for powering the

board. The included screw terminal block makes it easy to connect the load and load

supply wires directly to the board. This RC switch ships with a 1×4 terminal block and

male header pins included but not soldered in.

The Pololu RC Switch with Relay [https://www.pololu.com/product/2804] features a single-

pole, double-throw (SPDT) relay, allowing it to drive large, electrically isolated loads.

This board also has an integrated voltage regulator. It is available fully assembled

[https://www.pololu.com/product/2804] or as a partial kit [https://www.pololu.com/product/2805].

Please note that relays make a clicking sound when they are turned on or off, so the

RC Switch with Relay might not be suitable for applications requiring quiet operation.

The Pololu 4-Channel RC Servo Multiplexer [https://www.pololu.com/product/2806] is

an RC switch with an integrated quad 2-input multiplexer and a voltage regulator. It

allows easy switching of servo control between two independent sources. It is ideal

for applications in which you have two possible control sources and want to be able

to switch between them on the fly. The RC multiplexer is available fully assembled

[https://www.pololu.com/product/2806] or as a partial kit [https://www.pololu.com/product/2807].

In this guide, we use the term “RC switch” to refer to all members of the Pololu RC Switch family,

including the RC multiplexer.
