In the world of electrical control, precision and reliability are non-negotiable. When your application requires the simultaneous control of two separate circuits—either to turn two different components on at once or to ensure one circuit is disconnected while another is engaged—a Double Pole Single Throw (DPST) pushbutton switch is the essential component. Unlike simpler single-pole switches, a DPST configuration provides a higher level of safety and functional complexity by managing two independent paths through a single physical actuator. Whether you are designing industrial machinery, custom automotive interfaces, or high-end audio equipment, choosing the right DPST pushbutton requires a deep understanding of electrical ratings, mechanical durability, and environmental resilience.

A Guide to Selecting the Best DPST Pushbutton Switches
Understanding the DPST Configuration
The first step in your selection process is verifying that a DPST mechanism actually meets your logic requirements. A DPST switch operates two separate poles (circuits) using one single throw (on/off state). This is distinct from a DPDT (Double Pole Double Throw) switch, which allows for switching between two different paths. If your goal is simply to interrupt two lines of power simultaneously to ensure complete isolation, DPST is your standard. When shopping, ensure the switch is truly 'Double Pole'. Some budget options may appear to have multiple terminals but only actuate a single internal connection. Always map out your circuit diagram to ensure the two poles are truly independent and will perform the simultaneous break or make required for your safety protocols.
Electrical Ratings: Voltage and Amperage
The most common mistake in selecting pushbutton switches is ignoring the relationship between voltage and current. A switch rated for 10 Amps at 12 Volts DC will likely fail or arc dangerously if used in a 120 Volts AC application. You must evaluate your load type: inductive loads (like motors or solenoids) require significantly more robust switching capabilities than resistive loads (like LED indicators or heating elements) because motors create a momentary surge of current when activated. Look for a switch with a current rating that exceeds your maximum peak load by at least 20-30% to account for heat buildup and longevity. If you are working with high-voltage AC, ensure the switch is specifically rated for arc suppression to prevent the contacts from welding shut.
Mechanical Actuation and Feel
The 'user experience' of a pushbutton is defined by its actuation type: momentary versus maintained. A momentary switch (often called a 'normally open' or 'normally closed' momentary) only stays in the active state while your finger is pressing it. This is ideal for reset buttons, doorbells, or triggering a pulse. A maintained switch (latching) stays in position after being pressed, acting like a standard light switch. Beyond the logic, consider the tactile feedback. Industrial environments often benefit from 'heavy-duty' tactile feedback that confirms the switch has engaged, whereas precision instrumentation might require a smoother, more dampened press. Additionally, consider the 'travel distance'—how far the button must move to complete the circuit—as this affects the speed and ergonomics of your control panel.
Environmental and Physical Durability
Where will this switch live? If it is being mounted on a piece of heavy machinery in a factory, look for an IP (Ingress Protection) rating. An IP65 or higher rating ensures the switch is protected against dust and water splashes. For outdoor or marine applications, stainless steel or high-impact polymer housings are mandatory to prevent corrosion. Furthermore, consider the mounting diameter. Pushbuttons typically come in standard sizes like 12mm, 16mm, 19mm, or 22mm. Ensure your panel cutout matches the switch diameter to prevent wobbling or poor sealing. Finally, check the terminal type. Screw terminals are excellent for secure, high-torque connections in industrial settings, while solder lugs are better for compact, low-profile electronics where space is at a premium.

Quick answers about Dpst Pushbutton Switches before you buy.
DPST stands for Double Pole, Single Throw. This means the switch controls two separate electrical circuits simultaneously with one actuator, but it can only be in one of two states: ON or OFF.
Choose a momentary switch if you want the connection to break as soon as you release the button (like a doorbell). Choose a maintained switch if you want the button to stay in its new position after being pressed (like a light switch).
A DPST switch controls two circuits with one ON/OFF state. A DPDT (Double Pole, Double Throw) switch controls two circuits but allows you to toggle them between two different paths, effectively providing an ON-ON or ON-OFF-ON functionality.
It depends on the specific switch's electrical rating. Always check the voltage and amperage ratings printed on the housing or datasheet to ensure the switch can safely handle your load without arcing or overheating.
Contact rating refers to the maximum current and voltage the switch can safely interrupt. Using a switch rated for 5 amps on a 10-amp motor will cause the internal contacts to weld shut or melt, destroying the switch.
Yes. They are commonly available in panel-mount versions (requiring a hole in a chassis), PCB-mount versions (soldered directly to a circuit board), or through-hole styles for heavy-duty industrial applications.
For industrial environments, look for switches with metal bodies and high-quality contact materials like silver or gold-plated contacts to ensure reliable conductivity and resistance to corrosion.
