What Are Momentary and Latching Push Button Switches
Momentary switches complete a circuit only while pressed, providing temporary control action. Latching switches, in contrast, maintain their state until pressed again, making them ideal for toggling operations without continuous force.
Key distinctions include:
- Momentary → Immediate circuit closure → Suitable for start/stop commands requiring operator presence.
- Latching → State retention → Ideal for pump on/off controls where continuous operation is needed without holding the button.
Building on actuation type, understanding contact configurations guides proper wiring of normally open and normally closed circuits.
How Do Normally Open (NO) and Normally Closed (NC) Contacts Work
“Normally Open” (NO) contacts remain open with no power, closing only when the button is pressed. “Normally Closed” (NC) contacts are closed at rest and open on actuation.
NO contacts prevent unintended activation, while NC contacts ensure fail-safe shutdowns. These contact principles lead directly into material choices like illuminated or plastic push buttons.
What Are the Differences Between Illuminated, Metal, and Plastic Push Buttons
Before wiring, you must select the appropriate switch body material and illumination feature.
Metal housings excel under harsh environments, while plastic variants offer chemical resistance and lighter weight. Selecting the right configuration prepares you for common panel configurations.
Which Push Button Switch Configurations Are Common in Control Panels
Control panels often deploy SPST, SPDT, DPST, and DPDT switches to manage diverse circuits.
- SPST: Single pole, single throw for simple on/off.
- SPDT: Single pole, double throw to toggle between two circuits.
- DPST: Double pole, single throw to simultaneously control two feeds.
- DPDT: Double pole, double throw for reversible motor control.
Understanding these configurations ensures compatibility with PLC inputs, safety relays, and indicator lights.
