The pushbutton we’ll be working with is a 19mm metal push button switch with self-locking functions and five pins. While latching switches, on the other hand, can remain depressed until you press the button again to release it. If you have a momentary switch, you’ll have to maintain the pressure you place on the control to take action. Once you press the button again, the internal spring will retract and return the push button connected to its former state.Īdditionally, you can choose between a pushbutton switch with regular “open contacts” or “closed contacts.” Moreover, the process of pressing the switch can either close or open your electrical circuit. Plus, this action touches the stable connections found at the bottom of the switch. Thus, once you place pressure on the actuator or button, it depresses the internal spring and contacts. Most pushbutton switches use the same working principle. The types of pushbutton switches include: Storage Temperature ranges between -20 to +70 ℃.Operating Temperature ranges between -20 to +70 ℃.It has a MAX 100mOhm contact resistance.It uses a tactile feedback mode of operation.

The insert-molded terminal prevents a flux rise in the switch circuit.Its dielectric can withstand up to 250v AC for one minute.Tactile feedback provides a crisp click.Here, we’ve listed a pushbutton switch’s key features and technical specs. Push Button Features and Technical Specifications Also, when you press a pushbutton switch, it stays in that depressed state until you press it again to release it. While switches have permanent on and off positions, pushbuttons only have temporary on and off functions. Also, manufacturers would usually build push buttons with solid and durable materials like plastic or metal–so it doesn’t wear out from continuous use.Īdditionally, the surface of a pushbutton switch can be either flat or a shape that you can quickly press or depress with your finger.įurthermore, try not to confuse push button switches with regular switches.
