This breadboard-compatible module is an alternative to bulky power switches. It uses a small integrated slide switch to control a high-side power MOSFET that can deliver continuous currents up to around 16 A at 4.5 V to 40 V. The board features reverse-voltage protection and also makes it easy to control the MOSFET with an external switch or the digital output of a microcontroller. More product details

Product Description

Overview

The Pololu Pushbutton Power Switch is a compact, solid-state power switch that features built-in reverse-voltage protection and is controlled by a momentary pushbutton: one push turns on power and another push turns it off. This is a patented design initially created for use in our own products as an alternative to bulky mechanical switches. Because the switched current does not flow through the mechanical switch, a large variety of small, low-power switches can be used to control a substantial amount of power. The use of momentary switches also allows multiple switches to be used in parallel to control the power to one load.

The board has a small pushbutton already installed and offers convenient points for connecting external pushbutton or tactile switches in parallel. It also offers several alternate pushbutton connection options that result in push-on-only or push-off-only operation, and additional inputs enable further power control options like allowing the load to turn off its own power, which can be beneficial when used with battery chemistries sensitive to over-discharging.

Warning: Do not use this switch as an emergency cutoff or similar safety disconnect in applications where failure to cut power could lead to injury or property damage.

The switch and control inputs control the state of a latching circuit that in turn controls a pair of power MOSFETs through which the main current flows. Four versions of the Pololu Pushbutton Power Switches are available:

Mini Pushbutton Power Switch LV
Mini Pushbutton Power Switch SV
Big Pushbutton Power Switch MP
Big Pushbutton Power Switch HP

The two Mini Pushbutton Power Switches are smaller, lower-current versions that are useful for applications with tight size constraints or lower power requirements. Also, the the Mini LV is the only one of the four that works below 4.5 V; since it can operate down to 2.2 V, this version can be used with a single lithium cell battery.

The pinout of the Big version is the same as the pinout of the Mini version with several additional redundant connection points for convenience, including main power connections that are compatible with 5 mm terminal blocks.

Spezifikation

The Pololu Pushbutton Power Switch works well in its intended application as a DC power switch for small robots, but because it is fundamentally different from a mechanical power switch, the benefits and drawbacks of the components must be fully considered.

Benefits over mechanical switches:

Compact size
Reverse-voltage protection
Allows multiple (parallel) switches for improved user interface
Better turn-on characteristics than a bouncing mechanical switch
Limited LC spikes for low-resistance loads
Allows self-shutoff (OFF input)
Allows external digital device to control the power state (ON and CTRL inputs)
Breadboard and perfboard compatible (0.1?-pitch)

Drawbacks compared to mechanical switches:

Switch is one-directional (power applied to VOUT cannot be switched to VIN)
Limited operating voltage range
Switch can lose its state when power is disconnected (the switch typically defaults to being off when power is first applied, but it can default to being on near the upper end of the operating range)
Switches DC only (does not maintain state through power disruptions or excessive noise)
No complete isolation in off state
