Description: This product is a power switch implemented as a pair of P-channel MOSFETs configured as a high-side switch with reverse voltage protection and controlled by a micro slide switch. Because the main current does not go through the controlling mechanical switch, a variety of switches can be used without concern for the current they can carry. For example, a small slide or toggle switch can be mounted conveniently on a control panel with thin wires running to it, while the main power path can be shorter and with thicker wires. Pushbutton or tactile switches can also be used for momentary switching applications.

  • Reverse Voltage Protection: Yes
Using the MOSFET Slide Switch: In the most basic application, power can be applied to the VIN and ground pins, with the on-board mini slide switch controlling power on the VOUT pins. To use an alternate SPST switch to control the MOSFETs, set the on-board slide switch to the off position and connect the alternate switch between ground and the switch control terminal, which is accessible both in the center of the board and along the side.



If the physical switch is in the “off” position, the switch state can also be controlled by a digital signal (e.g. from a microcontroller) via the “ON” control pin. Driving the “ON” pin low (or leaving it disconnected) will leave the switch off; driving the pin beyond approximately 1 V will turn the switch on. The maximum voltage for the “ON” pin is 30 V, independent of the switch voltage (VIN).

The MOSFET Slide Switch is compatible with solderless breadboards and perforated printed circuit boards with standard 0.1″ spacing. For such applications, the included male header pins can be soldered to the switch PCB. Alternatively, wires can be soldered directly to the switch PCB for non-breadboard applications. For high-current applications, make sure that the wires can safely carry the current. Two pads/pins are provided for each of the power nodes, and multiple pads should be used for applications drawing over 5 A.

Thermal and power dissipation considerations: Because MOSFETs in the on state are effectively resistive, the power heating the board is proportional to the square of the current flowing through it. The comparison table near the top of this page shows typical currents that heat the MOSFETs to 55°C, where the MOSFETs start being noticeably warm but are still generally safe to touch, and currents that heat the MOSFETs to 150°C, the absolute limit for the MOSFETs. With adequate cooling, or for brief periods if the MOSFETs are not hot to begin with, currents up to the listed maximums are attainable.
