What is the Difference Between Momentary and Alternate Push Buttons?

Ever pressed a button and wondered why it only works while you’re holding it down, while others stay on even after you let go? 

That’s the quirky difference between momentary and alternate push buttons. These little switches are everywhere, from your doorbell to your car’s power windows, but understanding their unique behaviors can be a bit puzzling. 

So, if you’re curious about the mechanics behind these buttons and how they control different actions, you’re in for a treat. Let’s unravel the mysteries of momentary and alternate push buttons and discover how they shape our interactions with everyday devices.

Momentary Pushbutton Switches

Momentary pushbutton switches, often referred to as “spring return” switches, are designed to provide temporary action. Their internal spring mechanism ensures that the contacts return to their normally open state once the button is released. This makes them ideal for scenarios where a continuous signal is not required, such as:

• Doorbells and Alarms;
• Car Horns
• Remote Controls; and
• Industrial Controls

Latching Pushbutton Switches

Latching pushbutton switches, also known as “maintained” or “stay-put” switches, are designed to hold their position after being pressed. They toggle between open and closed states with each press, allowing for continuous circuit control. This makes them suitable for applications like:

• Power Switches
• Light Switches
• Selector Switches

Momentary vs. Latching

So, what’s the difference between momentary and alternate pushbuttons?

The difference between momentary and alternate pushbuttons is momentary pushbutton switches close the circuit only while the button is physically pressed. Latching pushbutton switches toggle between open and closed states with each press, maintaining the last selected state. 

This fundamental difference in operation leads to distinct applications and use cases for each type.
